The FPM filters are designed to be line-mounted with BSP threaded ports for
hydraulic connections. Threaded holes are machined on the head for possible
filter bracket fixing .
— The replacement of the filter element can be easily carried out by using a
normal hexagon spanner to unscrew the bowl of the filter, which has a suitably
— FPM filters are designed to be installed on medium pressure lines up to 210
bar; the filter elements are made of high efficiency filtering materials and are
available with three different filtration degrees:
F05 = 5 µm absolute (β
>100 – ISO 4401:1999 class 17/15/12)
F10 = 10 µm absolute (β
>100 – ISO 4401:1999 class 18/16/13)
F25 = 25 µm absolute (β
>100 – ISO 4401:1999 class 19/17/14)
— The filters are always supplied with a by-pass valve.
— The filter elements are available in the standard version (S) or in the longlasting version (L) is able to hold high quantities of contamination material. For
all filter elements the collapsing differential pressure is 20 bar.
— All the FPM filters are designed to incorporate a visual-differential or a visualelectric clogging indicator to be ordered separately (see paragraph 5).
