Suction filters

Fcl in-line suction filters, with paper cartridge

Fcl in-line suction filters, with paper cartridge

These small in-line filters retain impurities and very fine dust, interfering with the capacity in a negligible manner. Thanks to their reduced size, they can be directly installed onto vacuum piping, close to the services (vacuum cups, vacuum clamping systems etc.) for a fractionated filtration and a better visual control of all the plant suction points. They are composed of a cylindrical transparent plexiglass body closed by two anodised aluminium flanges kept in place by seeger rings, where all the threaded male or female connections and seals are located. Inside there is a filtering cartridge with a filtering degree equal to 7 μ, which is made with a special treated paper that is pleated to increase the filtering surface. The filters can be inspected by simply removing one of the flanges. Due to the paper filtering element, these filters are not recommended in presence of water or oil vapours or condensations. Technical features:
Working pressure: from 0.5 to 3000 mbar abs.
Fluid temperature: from -20 to +60 °C
Filtering degree: 7 μ.

Fb suction filter with metal cartridge

Fb suction filter with metal cartridge

Preventing impurities from reaching the vacuum pump is fundamental to guarantee the correct operation and long duration. This range of filters, to be placed on the vacuum pump suction inlet or on the plant pipeline, has been designed for this purpose. Their simple and rational structure features threaded connections for the installation and a lid, very easy to open, to allow easily cleaning the filtering cartridge. The lids are made with die-cast aluminium, as are the containers, except for the models FB 5, FB 10 e FB 20 which are in transparent plastic material (cellulose acetate), particularly resistant to shocks. The standard filtering cartridges are in profiled stainless steel mesh, with a filtering degree equal to 44 μ. Upon request, they can be supplied with a filtering degree equal to 100 or 300 μ. The capacity of these filters ranges from 5 to 300 cum/h. Technical features:
Working pressure: from 0.5 to 3000 mbar abs.
Fluid temperature: from -20 to +90 °C for filters with aluminium container, from -20 to +50 °C for filters with containers in transparent plastic material
Filtering degree: 44 μ

Fc suction filters with paper cartridge

Fc suction filters with paper cartridge

These filters have been designed to allow vacuum pumps to operate even in very dusty environments. Installed onto the pump suction inlet, they are able to retain fine and impalpable dust interfering with the capacity in a negligible manner. The filtering cartridge is made with a special treated paper with a filtering degree equal to 5 ÷ 7 μ, which is pleated to increase its surface and is contained in a double perforated sheet steel enclosure. The filtering cartridge container, as well as the lid, is made with sheet steel and varnished with a special anti-oxidation paint. A seal located between the lid and the container guarantees a perfect vacuum seal between the two elements. The release clamps applied onto the container allow a quick opening of the lid for the filtering cartridge inspection or replacement. Due to their paper filtering element, these filters are not recommended in case of water or oil vapours and condensation. Technical features:
Working pressure: from 0.5 to 2000 mbar abs.
Fluid temperature: from -20 to +60 °C
Filtering degree: 5 ÷ 7 μ

Fo oil-bath suction filters

Fo oil-bath suction filters

In presence of a considerable amount of fine or impalpable dust, the traditional suction filter would require a cartridge with a filtering degree so high that, along with reducing its operation autonomy, it would also reduce the vacuum pump suction capacity. Oil-bath suction filters have been studied in order to overcome this problem. The main feature of these filters is the ability to retain the smallest and most impalpable dust particles, without reducing the vacuum pump suction capacity. Oil-bath filters are composed of a sheet steel head and container coupled with an interposed seal and clamped by release clamps. Inside, besides the oil bowl, there are two steel wool filtering cartridges, one of which is detachable and washable, while the other is fixed. The release clamps guarantee easy access for cleaning operations. They can be used with any kind of oil, even drain oil, as long as it has a minimum viscosity degree. The ideal oil is the same one used for the pump. Oil-bath suction filters are not recommended for dry vacuum pumps. They are currently available for capacities up to 300 cum/h. Technical features:
Working pressure: from 0.5 to 2000 mbar abs.
Fluid temperature: from -20 to +90 °C
Filtering degree: ≤1 μ.

Fs syphon suction filters

Fs syphon suction filters

These filters retain impurities and liquids extracted through vacuum cups or vacuum clamping systems, preventing them from entering into the vacuum pumps. They are composed of:
- A transparent Plexiglas cylindrical container with an extractable lid to allow inspection and cleaning.
- A check valve located on the suction inlet for preventing the air from returning in the filter when the pump is idle.
- A stainless steel mesh filtering cartridge with a filtering degree equal to 44 μ, also located on the suction inlet to retain dust and solid impurities.
- A 2-way manual valve for service vacuum interception.
- A 2-way manual valve for restoring the atmospheric pressure inside the filter.
- A radial vacuum gauge the direct reading of the vacuum level.
- A magnetic level switch that stops the pump when the sucked liquid exceeds the safety level.
- A rigid pipe connected to the service to convey the air flow and the sucked liquid to the bottom of the container.
- A check valve at the bottom of the filter to automatically drain the sucked liquid and impurities every time the atmospheric pressure is restored inside the filter.
- A cock applied on the aforementioned check valve for manual liquid drainage.
- A sturdy metal bracket for fixing the filter to the wall.
Technical features:
Working pressure: from 0.5 to 2000 mbar abs.
Fluid temperature: from -5 to +50 °C
Filtering degree: 44 μ

Syphon filter system with automatic by-pass fs 50 bp

Syphon filter system with automatic by-pass fs 50 bp

This system is composed of two syphon filters. It starts working with suction through filter 1 while filter 2 is excluded. When the sucked liquid reaches the level switch floater via the 1” 1/2 3-way vacuum interception solenoid valves, the suction is automatically commuted to filter 2. The inlet of atmospheric air in filter 1, via the 1/2” 3-way solenoid valve installed on its lid allows automatically draining the liquid through the check valve with cock located at the bottom of the filter. Once the liquid has been drained after a set time (this operation can be timed), the solenoid valve returns to its initial position, thus allowing the recreation of vacuum inside the filter, through a small flexible pipe connected to the main vacuum piping. Thanks to this solution, there is no reduction of the vacuum level at the service when the suction exchange between the two filters occurs. This exchange occurs when the liquid reaches the level switch floater in filter 2 and from that moment on, the operations described above will be repeated. The filter system is composed of:
- 2 Plexiglas syphon filters with aluminium lids and with accessories, with a capacity of 38 litres each.
- 2 1” 1/2 gas servo-controlled 3-way vacuum solenoid valves art. 07 06 11.
- 2 1/2” gas servo-controlled 3-way solenoid valves art. 07 03 11.
- 4 1” 1/2 gas 2-way manual valves for vacuum interception art. 13 07 10.
- 2 1/2” gas 2-way manual valves for the inlet of atmospheric air art. 13 03 10.
- 1 switchgear enclosed in a watertight metal casing for Volt 230/ 50 Hz single-phase electric voltage.
- 1 frame in varnished steel profiles for the assembly of all the components described above.
The syphon filtre system with automatic by-pass is recommended when there is a considerable presence of liquid in the sucked fluid and the machines cannot be stopped for draining the sucked liquid with traditional syphon filtres. Technical features:
Working pressure: from 0.5 to 2000 mbar abs.
Fluid temperature: from -5 to +50 °C
Filtering degree: 44 μ.
