In-line, FCL, FPL and FIL filters

These large in-line filters retain impurities and very fine dust, interfering with the flow rate in a negligible manner.
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.
The filtering cartridges illustrated and described on this page, installed in their own container, are produced with different materials that can be identified with the following abbreviations:

- Series SP. Pleated paper filtering cartridge with compression sealing.
- Series SS. Pleated polypropylene mesh filtering cartridge with compression sealing.
- Series SA. AISI 304 stainless steel mesh filtering cartridge with compression sealing.
- Series RP. Pleated paper quick coupling filtering cartridge with double O-ring.
- Series RS. Pleated polypropylene mesh quick coupling filtering cartridge with double O-ring.
- Series RA. AISI 304 stainless steel mesh quick coupling filtering cartridge with double O-ring.

Given the paper filter element, it is not recommended to use these filters in the presence of water and oil vapours or condensation.
The filters can be inspected by simply removing one of the two flanges.
