These extremely compact vacuum switches give or remove a pneumatic signal, depending on the model, when a certain adjustable level of vacuum is reached.
The pressure differential existing between the set maximum value and that of the signal recovery at rest is not adjustable.
They are particularly suited for controlling vacuum generators and for activating pneumatic valves.

Vacuum regulators with pneumatic adjustment differ from the previous ones for the way they adjust the level of vacuum; in fact, instead of acting manually on the adjustment screw, it is necessary to act on the pneumatic cylinder compressed air supply: the higher the pressure, and the higher the level of vacuum and vice-versa.
Vacuum regulators are used to adjust the pre-set level of vacuum and keep it constant (secondary vacuum), regardless of the pump vacuum level or the vacuum level (primary vacuum).
Unlike the vacuum adjusting valves, regulators do not introduce atmospheric air into the circuit, thus producing more gripping points with different vacuum values, from only one vacuum source.
Their operating principle is based on the contrasting action between a pneumatic cylinder with short stroke and a fluctuating piston driven by the pressure differential existing between the secondary vacuum and the atmospheric pressure.

Multi-function modules with built-in vacuum solenoid valves
The needs of technical designers in the packaging sector and in the automation sector in general to have more vacuum combined with different functions in the smallest possible space has led us to design and implement this new series of multi-function modules.
Each module has two internal solenoid valves built inside it. Their ducts house the seats for the flow control valves, which can be operated externally by means of special knobs. Various connections made at different points allow for connection of the module to instruments for reading and checking the level of vacuum, such as vacuum gauges, vacuum switches, transducers, etc.
There are three modules currently available:
- Module A: the basic module with two integrated 1”1/2 and 1” solenoid valves, two flow regulators and several additional connections.
- Module B: with two integrated 1/2 "and 1" solenoid valves and two flow regulators. Can be combined with modules A and C.
- Module C: module with two integrated 1/2” solenoid valves, a flow regulator and an additional connection.
Can be combined with module A or B.
The combination of modules A, B and C, feasible using special stainless steel tie-rods, allows for the application of various functions from a single source of vacuum, as well as allowing for the elimination of numerous pipes and fittings, often causing leaks. The multi-function modules are supplied already tested to a guaranteed final level of vacuum of 0.5 mbar and perfectly sealed.
The technical characteristics are those of the pneumatically actuated three-way vacuum solenoid valves:
- Servo-control pressure: 6-7 bar; 4-6 bar for version LP, with non-lubricated compressed air, 5 micron filtration, according to standard ISO 8573-1 class 4
- Operating pressure: from 0.5 to 3000 absolute mbar
- Electric coils: fully plastic-coated in synthetic resin, watertight, insulation class F (up to 155°C) as per standard VDE, with 3 mm two-terminal electrical connections for connectors in compliance with EN 175301-803
- Protection degree IP 54; IP 65 with connector inserted.
- Tolerance permitted on the nominal voltage value: ± 10%
- Electrical power of the coils: from 1 to 2 W, depending on the electrical voltage
- Temperature of suctioned fluid: from – 5 to + 60°C
The ideal use of these multi-function modules is on vacuum thermoformers and vacuum thermo-welders, but they are also widely used on packaging and filling machines in the packaging sector and in all those cases where it is necessary to manage the vacuum at different points and times. Upon request, the modules can be customised and implemented with solenoid valves up to 3” gas. Contact our technical department for further information.
These valves have the same features of the previously described check valves, but they are made with anodised aluminium, which makes them particularly light. The seal is guaranteed by an EPDM membrane instead of the metal shutter with NBR seal.
Thanks to these features and their modern design, they are recommended for pneumatic vacuum generators and, of course, on vacuum pumps.

Servo-controlled 3-way vacuum solenoid valves with two electric coils
These solenoid valves have the same function and the same structure as the previously described three-way valves.
Even their structure is the same, but their distinctive features are the two coils that with a simple electric impulse exchange the shutter positions and keep them in this position till the next impulse even in absence of compressed air at the servo control and of electric current.
This is the reason why their use is especially recommended in all those cases requiring maximum connection security at the vacuum source, even in the absence of electrical and pneumatic power supply.

Single-stage vacuum generators with ejector FVG 8 and FVG 12
Specifically designed for very high frequency gripping and release applications, these single-stage vacuum generators are based on the Venturi principle and are equipped with a pneumatic ejector, which can be implemented on request through the M7 connection on the lid, to allow maximum speed in restoring the atmospheric pressure of use.
The key features are its considerably reduced weight, supply compressed air pressure of less than 4 bar, low energy consumption, simplicity of installation and low noise level during use, thanks to the high sound dampening silencer installed as standard on the generators.
The pneumatic ejector can be deactivated simply by means of a membrane integrated onto the generators.
These generators, like the previous ones, are also fully made with anodised aluminium.
Product codes: FVG8 FVG12
Single-stage vacuum generator operation is based on the Venturi principle.
Supplying the generator with compressed air in P, vacuum will be generated at connection U, while both the supply and the sucked air will be released through R.
By interrupting the air supply in P, the vacuum effect in U will also stop. The optimal air supply pressure is normally 6 bar, but for generators with the letters LP in their item, a pressure lower than 4 bar is sufficient to obtain the best performance. Upon request, the vacuum generators can be supplied with a high sound suppression silencer installed on the R exhaust connection.
The single-stage vacuum generators are generally used to control vacuum cups, for gripping and handling non-porous objects and equipment with low flow rate requirements.
They are fully made with anodised aluminium, with brass or aluminium ejectors, depending on the items.
Product codes: 150110 150110LP 150115LP
This series of single-stage vacuum generators, also based on the Venturi principle, can be supplied for optimal supply pressures of 4 or 6 bars. Thanks to their shape, they can be installed directly on the user device and used at the most suitable supply pressure, depending on the desired level of vacuum.
They have different capacities and can be used in all gripping systems with vacuum cups, for gripping and handling objects that are not very porous and on equipment with limited capacities. They are available upon request with an SSX 3/8" R high sound suppression silencer, installed on air exhaust R.
They are fully made with anodised aluminium, with brass or aluminium ejectors, depending on the items.
Product codes: VG03 VG03LP VG05LP
Single-stage vacuum generators with ejector 15 02 10, 15 02 10 LP and 15 02 15 LP
This single-stage vacuum generator operation is based on the Venturi principle. When the generator is supplied with compressed air in P, the vacuum will be generated at connection U and the supply air with the suctioned air will be discharged in R. During the operating cycle, a chamber inside the generator body will be supplied and, when supply stops in P, the compressed air accumulated in it will be discharged through the U connection, quickly the restoring atmospheric pressure of use.
If when using U, for example, it is connected to a vacuum cup, it will disconnect much faster with this ejector system with respect to the previously described vacuum generators. The optimal air supply pressure is normally 6 bar, but for generators with the letters LP in their item, a pressure lower than 4 bar is sufficient to obtain the best performance. They are fully made with anodised aluminium, with brass or aluminium ejectors, depending on the items.
Product codes: 150210 150210LP 150215LP
Single-stage vacuum generator with ejector 15 06 08 SX and 15 06 10 SX
These have the same technical features as 15 05 08 SX and 15 05 10 SX, with the addition of the pneumatic ejector. For the ejection system, air accumulated in a special chamber inside the generator body during the operating cycle is automatically discharged in connection to use U, once supply in P is completed and suitably dosed by means of a screw-type flow regulator, for quick restoration of the atmospheric pressure. Optimal supply pressure is less than 4 bar. A high acoustic dampening silencer, set on exhaust air discharge R, reduces noise to a minimum and is an integral part of the generator. These generators, like the previous ones, are also fully made with anodised aluminium.
Product codes: 150608SX 150610SX
This new range of vacuum generators also makes use of the Venturi principle.
Their distinctive feature compared with traditional vacuum generators are the two air and vacuum supply connections located in-line on the same axis, while the exhaust connection of the sucked and exhaust air is orthogonal to them and is located on the generator circumference. These vacuum generators are easy to disassemble, thus allowing visibility and access to all the components. The advantages of these generators include reduced overall dimensions, easy maintenance and easy assembly to the vacuum cup supports or to the vacuum cup holders.
As a standard, they are equipped with pressed stainless steel suction filter and a special microfibre silencer, which is wrapped around the exhaust connection, making them particularly silent. They are fully made with anodised aluminium.
Product code: PVP1
These vacuum generators also operate based on the Venturi principle.
The feature that distinguishes them from classic vacuum generators are the two air supply and the vacuum connections, located on the same axis, while the connection relative to the intake-air discharge and exhaust air connections are set orthogonally to them.
The advantages of this configuration are less bulky dimensions, easy assembly, and ease of maintenance. These vacuum generators can be assembled directly onto the vacuum cup supports or on cup holders.
They are fully made with anodised aluminium, except the exhaust nozzle which is made with brass.
Product codes: GV1 GV2 GV3
This particular sleeve valve has been constructed to ensure a faster restoration of the atmospheric pressure inside the vacuum cups when the load is disconnected.
When it is pneumatically operated at the end of the cycle, it closes the generator discharge connection, conveying the supply air in the connection of use. In this way, the vacuum cups are immediately detached. It is suitable for generators with capacities not exceeding 15 mc/h and designed especially for series MSVE.
It is made of anodised aluminium, with an integrated silicone sleeve membrane.
Product code: 070290
Single-stage vacuum generator PVP 2 M, PVP 2 MM1, PVP 2 MM2 and PVP 2 MM3
The vacuum generators on this page are based on the same Venturi principle of those previously described and provide the same technical performance. They however differ in their structure.
The vacuum connection U is in fact threaded to allow for assembly of a vacuum cup with male or female support while, on the same axis but on the opposite side, a hole with metric threading allows for the generator to be installed directly on the machine or on the cup holders equipped with springing.
They are fully made with anodised aluminium, with brass ejectors. Equipped with a vacuum cup, these are they are truly self-contained gripping units. They are suited for vacuum cup operated loaders or handlers, for gripping sheet steel, glass slabs, plastic panels and other similar products.
Upon request, they can be supplied with a high sound suppression silencer installed on the R exhaust connection.

COAXIAL SHUTTER SERVO-CONTROLLED PNEUMATIC VALVES
These coaxial shutter valves, pneumatically driven by a vacuum switch or an alternative source, are able to intercept the compressed air supply to the vacuum generators, with pressures between 1.5 and 7 bar. They must be chosen based on the generator power supply connection and the required air quantity.
Product codes: 070071 070171 070271
COAXIAL SHUTTER SERVO-CONTROLLED PNEUMATIC SOLENOID VALVES
The function of these solenoid valves is to intercept the compressed air supply to the vacuum generators. Interception through an original coaxial shutter allows the supply of large quantities of air, thus ensuring greater gripping speed of the vacuum cups.
They are composed of an anodised aluminium body with an integrated coaxial shutter, pneumatically operated by a micro solenoid valve with low absorption electric coil, capable of managing operating pressures between 1.5 and 7 bar.
They can be controlled via vacuum switches or simple electrical switches.
Thanks to their compactness, it is also possible to install them directly on the vacuum generators, thus eliminating unnecessary pipes and negative volumes.

Vacuum generators PVP ... SX/SXLP, operate making use of the previously described Venturi principle.
A special new generation silencer installed on them makes them very silent and, thanks to its shape, prevents them from becoming clogged, also allowing the suction of saturated fluids of water condensates or oils, mixed with fine or impalpable powders.
They are supplied as standard with a vacuum gauge for reading the level of vacuum. An additional connection on the body of the generator allows the installation of a vacuum switch for signalling the level of vacuum, or of a pneumatic solenoid valve for a quick restoration of the atmospheric pressure of use. They are fully made with anodised aluminium, with stainless steel ejectors and screws.
These vacuum generators can be used for connecting one or more vacuum cups or equipment with flow rate requirements within the shown values and can operate in particularly dusty or damp environments. Available with suction rates between 8.3 and 18 m3/h and supply pressure 4-6 bar, for items SX and 1-3 bar for items SXLP.

Multi-stage vacuum generators - General description
Our multi-stage vacuum generators produce a maximum vacuum of 90%, equal to a final vacuum level of 100 mbar abs., with different suction capacities. They operate by use of compressed air from 1 to 6 bar. Working principle
Each ejector is based on the Venturi principle: the supply fluid (compressed air) is led high speed by a convergent pipe into the fluid to be extracted (volume of the air to be sucked). This mixture is then led into two or three divergent pipes, where its kinetic energy is transformed into pressure energy for it to enter in the environment at a higher pressure (atmospheric pressure at the exhaust). Technical features
The main asset of multi-stage vacuum generators is its ability to exploit the kinetic energy of the supply compressed air via several specially dimensioned in-line ejectors, before releasing it in the atmosphere. This system allows, given the same capacity, a reduced compressed air consumption compared to the single-stage vacuum generators.
The suction flow rate is indirectly proportional to the differential between the pressure of the fluid to be sucked and the external (atmospheric) pressure.
The reduced size and weight make multi-stage vacuum generators compact in relation to their great suction capacity.
The absence of moving parts make them particularly silent and allow them to be used continuously, without developing heat. Being supplied exclusively by compressed air, these vacuum generators are explosion-proof and can be used in work environments with temperatures ranging from -20 to +80 °C.
They are fully made with stainless materials.
Thanks to all these features, a good filtration of the supply and sucked compressed air is sufficient to make these generators are fully maintenance-free.
These new design vacuum generators feature multiple state of the art ejectors assembled onto small modules. One of their distinctive features is their great suction flow rate compared to their reduced size.
With a compressed air supply of 4 - 5 bar, they can produce a maximum vacuum equal to 85% and a suction flow rate of 3.6 - 18 m3/h, according to the number of modules.
The silencer is built-in.
They are fully made with slightly anodised alloys and can be installed in any position. The multi-stage vacuum generators in this range are suited for interconnecting vacuum cup gripping systems and, in particular, in the industrial robotics sector, which requires equipment with excellent working performance, but with weight and size reduced to the minimum.
Product codes: M3 M7
VACUMANAGER VM series units are integrated electro-pneumatic circuits designed to supply and manage single-stage and multi-stage vacuum generators. VM units house the following in an anodised body/distributor machined from billet aluminium:
_ Digital vacuum switch with display (standard), also available on request in a version with IO-Link communication;
_ Compressed air supply valve;
_ Blow off valve;
_ Flow regulator for the blow off valve.
A compact electro-pneumatic control circuit that incorporates all components for the management of vacuum and blow off generation in a handling system equipped with vacuum cups and powered by pneumatic vacuum generators (single-stage or multi-stage).
In combination with the Vuototecnica Energy Saving cables, these represent the best solution in terms of energy efficiency, as they limit the consumption of the compressed air supplying the pneumatic vacuum generators to the time strictly necessary to empty the vacuum cups.
This energy-saving solution is even more valued and appreciated in all vacuum cup handling operations for products with excellent sealing or with micro-porosity (metal sheets, glass, wood or plastic veneered panels, etc.).
Vuototecnica also recommends VM units for handling all Octopus gripping systems equipped with pneumatic vacuum generators and shut-off valves.

These vacuum generators share the same technical features as the others of the M series described above. Their distinctive feature is their silent operation.
In fact, along with the built-in silencer, they also have an external SSX silencer for a further noise reduction.
These generators are particularly recommended in work environments where the noise level must be kept within very low values.
Product codes: M3SSX M7SSX
Single-stage and multi-function vacuum generators series MSVE - General description
The vacuum generators of this new series can fully drive a negative pressure gripping system. By means of coaxial shutters, the original compressed air supply system feeds large quantities of air to both the ejectors and the ejection system, thereby ensuring faster gripping and release of the load.
These vacuum generators are equipped with single-stage ejectors, are powered by low pressure (max. 4 bar), and feature an extremely high emptying speed in relation to their suction flow rate. All this allows for increasingly faster high-performance work cycles.
Two micro solenoid valves manage the compressed air supply to the vacuum ejector and adjustable discharge blow off. The intensity and duration of the latter are managed through a screw-type flow regulator. The check valve built into the suction connector maintains the vacuum in the event of a power outage.
A digital vacuum switch, equipped with a display and commutation LED, manages the compressed air supply and provides a signal to start a cycle under safety conditions. An anodised aluminium distributor with vacuum connectors has an integrated suction filter that can be easily inspected.
By activating the compressed air power micro solenoid valve, the generator creates vacuum for use. As soon as the set maximum value is reached, the digital vacuum switch acts on the electric coil of the micro solenoid valve and stops the air supply, reactivating it when the vacuum falls below the minimum level.
Besides maintaining the vacuum level within set safety values (hysteresis), this modulation allows for considerable compressed air savings. A second signal from the vacuum switch (also adjustable and independent with respect to the first) can be used to start the cycle when the vacuum level reached is suitable for use. Once the work cycle is completed, the micro solenoid valve that supplies compressed air to the generator is deactivated while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure upon use.
The MSVE vacuum generators can be installed in any position and are suitable for suction gripping systems, handling metal sheets, glass, marble, ceramics, plastic, cardboard, wood, etc. and, in particular, for the industrial robotics sector, where equipment with excellent performance and limited weight and bulk are increasingly required.
Multi-stage and multi-function vacuum generators series MVG - General description

They are composed of a mono-block anodised aluminium structure onto which are assembled:
- A modular and silenced multi-stage vacuum generator.
- A micro solenoid valve for supplying compressed air to the generator.
- A micro solenoid valve for blowing the exhaust compressed air.
- An adjustable flow regulator for dosing the exhaust air.
- A unidirectional check valve, located on the suction inlet, for maintaining the vacuum in case of electricity failure.
- A digital vacuum switch provided with display and commutation LEDs, for managing the compressed air supply and for signalling the safety cycle start-up.
- An anodised aluminium manifold provided with vacuum connections and a built-in filter easy to inspect.
By activating the compressed air power micro solenoid valve, the generator creates vacuum for use. As soon as the preset maximum value is reached, the digital vacuum switch acts on the electric coil of the micro solenoid valve and stops the air supply, reactivating it when the vacuum falls below the minimum level.
Besides maintaining the level of vacuum within set safety values (hysteresis), this modulation allows for considerable compressed air savings.
A second signal from the vacuum switch (also adjustable and independent with respect to the first) can be used to start the cycle when the level of vacuum reached is suitable for use. Once the work cycle is completed, the micro solenoid valve that supplies air to the generator is deactivated while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure upon use.

Multi-stage, multi-function and modular vacuum generators, series GVMM – General description
Modular multi-function vacuum generators are true independent vacuum units that offer an entire vacuum control system.
They feature a reduced thickness and weight compared to their suction flow rate and they have been designed to be assembled with screws to one or more intermediate modules MI. The original internal connection system for the compressed air supply allows communication with no need for external manifolds.
This modular system allows increasing the number of independent vacuum units according to the requirements. In fact, you can order a multi-function vacuum generator and the intermediate modules with the desired capacities, already assembled, or you can assemble one or more intermediate modules to the GVMM generator that has already been installed on the machine, without having to make particular modifications. GVMM vacuum generators are composed of an anodised aluminium mono-block with lid, inside of which the silenced multiple ejectors are installed and the vacuum chamber and the compressed air supply connection are contained.
The following are instead installed on the outside:
- A micro solenoid valve for supplying compressed air to the generator.
- A micro solenoid valve for blowing the exhaust compressed air.
- An adjustable flow regulator for dosing the exhaust air.
- A digital vacuum switch provided with display and commutation LEDs, for managing the compressed air supply and for signalling the safety cycle start-up.
- An anodised aluminium or transparent Plexiglass manifold provided with vacuum connections with built-in suction filter, easy to inspect, and a check valve for maintaining the vacuum in case of electricity or compressed air failure.
By activating the compressed air power micro solenoid valve, the generator creates vacuum for use. As soon as the preset maximum value is reached, the digital vacuum switch acts on the electric coil of the micro solenoid valve and stops the air supply, reactivating it when the vacuum falls below the minimum level.Besides maintaining the level of vacuum within set safety values (hysteresis), this modulation allows for considerable compressed air savings.
A second signal from the vacuum switch (also adjustable and independent with respect to the first) can be used to start the cycle when the level of vacuum reached is suitable for use. Once the work cycle is completed, the micro solenoid valve that supplies air to the generator is deactivated while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure upon use.
GVMM multi-function vacuum generators can be installed in any position and are suited for interconnecting vacuum gripping systems for handling sheet steel, glass, marble, ceramic, plastic, cardboard, wood, etc., and, in particular, for the industrial robotics sector which requires equipment with excellent performance and several independent vacuum units for controlling several applications but with reduced size and weight.
Multi-stage, multi-function and modular intermediate vacuum modules series MI - General description
Intermediate modules are non-independent multi-stage and multi-function vacuum generators to be assembled to the generators of the GVMM range.
Their thickness and weight are reduced to the maximum compared to their suction flow rate and they have been designed to be enclosed between the lid and the base of the GVMM vacuum generator and fixed with screws. The internal connections for the compressed air supply allow communication between them and the basic generator, with no need for external manifolds.
This way, each module becomes an independent vacuum unit that can control an entire vacuum system.
They can be ordered in the desired amount and flow rate, either already assembled onto the GVMM multi-function vacuum generator, or separately, to be assembled to the GVMM generator previously installed onto the machine. In this case, we suggest ordering a screw kit suitable for the number of modules to be assembled.
MI intermediate vacuum modules are made up of the same elements that compose GVMM generators, except for the lid. They operate and they are used as the GVMM multi-function vacuum generator onto which they are assembled.
GVMM multi-function vacuum generators can be assembled with one or more intermediate modules, thus forming a modular vacuum system, featuring a compact shape and reduced size and weight.
As a standard, up to 6 vacuum units can be assembled, but using threaded bars instead allows assembling even more.

Single-stage and multi-function vacuum generators series AVG – General information
These generators are independent vacuum units capable of driving a vacuum gripping system They have been specially designed for the AUTOMOTIVE sector and they are equipped with single ejectors that, given the same flow rate as the multi-ejector generators, allow for a quicker grip.
They are provided as standard with a built-in pneumatic energy-saving device.
They are composed of an anodised aluminium mono-block structure, inside of which are installed the ejectors, the servo-controlled slide valve for the compressed air supply and are contained the vacuum chambers as well as the various connections.
The following are instead installed on the outside:
- A bistable impulse solenoid valve for controlling the slide valve.
- A solenoid valve for blowing the ejected compressed air.
- A flow regulator for dosing the ejected compressed air.
- Two silencers for removing noise from the ejected air.
- An aluminium manifold provided with vacuum connections with built-in:
• A pneumatic vacuum switch for managing the compressed air supply according to the set level of vacuum (energy saving).
• A check valve for maintaining the vacuum in case of electricity or compressed air failure.
• A suction filter, easy to inspect through the transparent polycarbonate lid.
OPERATION
By providing an electric impulse to the two-position solenoid valve, the compressed air supply slide valve will be activated and vacuum will be created at the application. Once the preset maximum value has been reached, the pneumatic vacuum switch acts on the servo-controlled valve and interrupts the compressed air supply, restoring it when the value returns below the minimum value.
Besides maintaining the level of vacuum within preset safety values, this modulation also allows a considerable saving of compressed air and occurs even in the absence of electricity. Once the work cycle is completed, the power supply solenoid valve is deactivated by means of an electrical pulse while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure of use.
AVG vacuum generators are fitted for the installation of a digital vacuum switch. Also these vacuum generators can be installed in any position.

Working principle
The compressed air supply blown into a ring chamber concentric to the device, flows at a very high speed towards the centre of the main pipe, thus forming a cyclonic effect. The latter creates a vacuum inside the device and leads a great volume of air towards its outlet.
Therefore, a variation of the air supply pressure will modify the level of vacuum and the amount of sucked air.
Features
The special shape of the flow generators and their straight-flow working principle allow for the suctioning and handling of various nature products without interference. Vacuum Jets are in fact suitable for the handling of powders, granulated products, sawdust, corn, metal chips, liquid or dry food products, etc., or for extracting fumes, coolant mists, water or oil condensation, etc.
The absence of moving parts allows them to be used continuously, without developing heat.
They do not require electricity; therefore, they can be used in work environments with hazardous environments where an ignition source would be dangerous.
Available in anodised aluminium and stainless steel.
Thanks to all these features, a good filtration of the compressed air supply will be sufficient to make these devices fully maintenance-free.
Also the construction of this cartridge vacuum generator was necessary in order to meet the demand for ever smaller and more performing devices in the packaging sector.
The compressed air supply pressure is between 1 and 3 bar, while the maximum level of vacuum is -52 KPa, with a flow rate of 2.6 m3/h.
Also the shape of these generators, like the previous ones described, allows for the suction of dust and small processing waste without clogging problems.
They are made of brass as standard, but upon request they can also be supplied in different metals.

Conveyor adjustable vacuum generators - General description
Working principle
These vacuum generators operate based on the Venturi principle.
Unlike those previously described, the ejectors with which they are supplied are adjustable, in addition to having a considerably higher flow diameter.
This detail lets them vary the flow rate and level of vacuum of the device, without altering the level of vacuum of the supply air.
The compressed air consumption is also related to the actual performance of the vacuum generator.
Features
The special shape of these adjustable vacuum generators, as well as their straight-flow working principle allow sucking and transferring products of various nature with no interference, just like flow generators, only, unlike these, they allow overcoming much higher level differences.
They are suited for transferring powders, granulated products, sawdust, metal chips, dry or liquid food products, etc. They are also recommended for controlling vacuum cups in presence of large amounts of dust or liquids, as well as for sucking fumes, cooling mists, water and oil condensation, etc. The absence of moving parts allows for a continuous use without developing heat.
The noise level, which is quite high for this kind of equipment, can be considerably reduced with a silencer screwed on the exhaust connection.
They do not require electricity, therefore, they can even be used in work environments with hazardous environments where an ignition source would be dangerous.
Available in anodised aluminium and stainless steel.
Thanks to all these features, a good filtration of the compressed air supply will be sufficient to make these devices fully maintenance-free.

A reference entity, ranging from engineering to services, that offers innovative and advantageous technical solutions under every point of view: performance, reliability, duration and operational economy. A significant demonstration of the Graphic Division specialisation is represented by the new range of products among which:
PNEUMATIC SUCTION AND BLOWING PUMPS
This new generation of highly versatile multiple-ejector pumps (multi-stage) are able to suction or blow as needed and represent a real evolution compared to conventional rotary vane pumps. Characterised by their new generation of ejectors, these pumps boast an excellent ratio between the quantity of air consumed and that suctioned (or generated), benefiting operational consumption. Their level of vacuum (or pressure level) and flow rate can be adjusted based simply on the air supply pressure. The state of the art hi-tech materials have considerably reduced the weight allowing them to be installed directly on the machine. The Vuototecnica research centre has focused its attention on noise reduction, with solutions that provide for full soundproofing and no moving parts, thus prolonging duration and eliminating any vibrations. Furthermore, these pumps are based on the Venturi principle which exploits the compressed air kinetic energy via in-line ejectors and, therefore, do not develop heat. The excellent filtration of the compressed air supply and intake air allows the intake of air free from oil, water condensates and impurities from between the sheets of paper to be separated in the working environment, with no pollution. Other assets of this safe and competitive technology include a minimal maintenance, limited to a regular filter cleaning operation, and reliability with no comparison. The pneumatic suction and blowing pumps are described in the following pages.
VACUUM CYLINDERS

Advantages include: high speed operation, automatic compensation of the height of the objects to be lifted, non-rotating stems and extremely easy fixing. These vacuum cylinders are illustrated and described on the following pages.
VACUUM CUPS
These come in a large variety of shapes and sizes, to guarantee a quick and safe grip and they can be provided in anti-abrasion natural para rubber, nitrile or oil-resistant rubber, silicone, FKM, polyurethane and other compounds, according to the requirements.Vacuum cups are described in detail in Chapter 1.

Suction units with syphon filter GA FS 5 and GA FS 10
These suction units with syphon filter allow sucking fluids saturated with condensation or mixed with water and liquids. They share all the best technical features of syphon filters and vacuum generators. In fact, they keep liquids and solid impurities, while the vacuum generator can suck fluids saturated with vapours or liquid condensation without compromising its performance.
These devices are composed of:
- A standard syphon filter described in Chapter 5.
- A compressed air-fed multi-stage vacuum generator.
- A pneumatic vacuum switch for adjusting the level of vacuum
- A vacuum gauge for a direct reading of the level of vacuum in the container.
- A pneumatic valve for supplying the vacuum generator operated by the vacuum switch
- A sleeve valve for compressed air interception.
The level of vacuum, preset with the vacuum switch, is automatically maintained in the Plexiglass container. These suction units with syphon filter are suited for vacuum cup clamping systems for gripping glass, marble, granite, light alloys and in all those cases with a considerable presence of refrigerating liquids.
They are also recommended for suctioning creamy or muddy substances which can be difficult to handle with traditional pumps.
These suction assemblies are fed by compressed air at a pressure of 4-6 bar only. Available in other versions upon request. Technical features
Operating pressure: from 0.5 to 1000 absolute mbar
Fluid temperature: from -5 to +50°C
