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 flow rate in a negligible manner. Thanks to their reduced size, they can be directly installed onto vacuum piping, close to the utilities (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 two flanges. Due to the paper filtering element, these filters are not recommended in presence of water or oil vapours or condensations.
Technical features
Operating pressure: from 0.5 to 3000 absolute mbar
Fluid temperature: from -20 to +60°C
Level of filtration: 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 flow rate.
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 flow rate.
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 m3/h.
Technical features
Operating pressure: from 0.5 to 2000 absolute mbar
Fluid temperature: from -20 to +90 °C
Level of filtration: ≤1 μ

FO long operation autonomy oil-bath suction filters

FO long operation autonomy oil-bath suction filters

In presence 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 flow rate.
Oil-bath suction filters have been studied in order to overcome this problem.
The main feature of these filters, in addition to their high autonomy, is their ability to retain the finest suctioned impalpable dusts without reducing the suction flow rate of the pump.
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.
Two visual indicators allow monitoring of the oil level and the degree of clogging.
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 200 and 300 m3/h capacities.

Syphon filter systems with automatic by-pass FS 50 BP and FS 60 BP

Syphon filter systems with automatic by-pass FS 50 BP and FS 60 BP

The system, composed of two siphon filters, operates initially with suction through filter 1 and with filter 2 excluded. When the suctioned liquid reaches the float on the level switch, automatically by means of the 1” 1/2 three-way vacuum interception solenoid valve for item FS 50 BP and 2” for item FS 60 BP, an exchange is made and suction passes through filter 2.
The input of atmospheric air into filter 1 via the ½” three-way solenoid valve installed on its lid, accumulated liquid is allowed to discharge automatically through the check valve with tap on the bottom of the filter. Once liquid has been discharged, after a pre-set time (this operation can be timed), the solenoid valve returns to its initial position, thus allowing recreation of a vacuum inside the filter through a small flexible hose connected to the main vacuum piping.
With this arrangement, there will not be any decrease in the level of vacuum for use when the suction exchange will be carried out between the two filters. This exchange will take place when the liquid reaches the level switch float on filter 2 and, from that moment, the operations described above will be repeated.
The filter system is composed of:
- 2 Plexiglas siphon filters with aluminium lids and complete with accessories, with a flow rate of 38 L each
- 2 1” 1/2 gas three-way servo-operated vacuum solenoid valves, item 07 06 13 for item FS 50 BP and 2” gas servo-operated vacuum solenoid valves, item 07 08 13 for item FS 60 BP
- 2 ½” gas three-way servo-operated vacuum solenoid valves, item 07 03 13.
- 4 1” 1/2 gas two-way manual valves for vacuum interception, item 13 07 10 for item FS 50 BP and 2” gas for vacuum interception, item 13 08 10 for item FS 60 BP
- 2 Manual ½” gas two-way valves, for atmospheric air input, item 13 03 10
- 1 Switchgear enclosed in a special watertight metal box, for single phase electrical voltage Volt 230/ 50 Hz
- 1 Coated profile steel frame to mount all above-described components
The siphon filter system with automatic by-pass is recommended in all those cases in which there is a strong presence of liquid in suction fluids and where machine shut-down for the discharge of liquids suctioned by traditional siphon filters is not allowed.
