Single-stage vacuum generator 15 01 10, 15 01 10 LP and 15 01 15 LP
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.

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.

In-line single-stage vacuum generators GV 1, GV 2 and GV 3
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.

Accessories for single-stage vacuum generators - Pneumatic sleeve valve
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.

Accessories for single-stage vacuum generators - Pneumatic coaxial shutter 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.

Single-stage vacuum generators PVP 7 SX / SXLP, PVP 14 SX / SXLP and PVP 18 SX / SXLP
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.

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.
