CLOGGING INDICATOR
A visual or visual-electrical diffe-
rential indicator is available as an
option and allows monitoring of
the element conditions, giving an
exact indication of the right time to
replace the element.
FILTER HOUSING
The head by high performance cast
iron and the bowl by extruded steel
ensure the best fatigue resistance
to the working pressures.
EASY ASSEMBLING
The manifold mounting is com-
pact and leak free.
SEAL GUARANTEED
A perfect O-ring seal is always
ensured as it is not dependent
on the tightening torque applied to
the bowl.
FILTER ELEMENT
The filter element is manufactured
with filter medias selected in the
UFI laboratory and mechanically
supported to maintain the highest
performances even at high diffe-
rential pressures.
For further technical informations
and other options see page 182-183.
