Filter in line assembly - medium pressure, FPM delivery filters are designed for assembly in line with 1/2 "or 3/4" threaded attacks, suitable for systems with operating pressure up to 315 bar. The replacement of the filter cartridge is simple and rapid: the end of the container is shaped to facilitate the unscrew through a hexagonal key. The filter cartridges are available in standard (S) or long -lasting version (L), both with collapse differential pressure of 21 bars. The FPM filters are equipped as standard with integrated by-pass valve, while the differential clog indicator, available in visual or electric-visual version, is to be ordered separately.
