1.1 FILTER HOUSING
Construction
The lter housings are designed
in accordance with international
regulations. They consist of a lter head
and a screw-in lter bowl. DFF lters
are suitable for ow in both directions.
The Dp optimized lters DFFX are also
suitable for ow in both directions and
the lter ports are in L conguration.
Standard equipment:
connection for a clogging indicator in
lter head
without bypass valve
drain screw with pressure relief
(for size DF/DFF/DFFX 330 and above)
1 or 2-piece lter bowl available as an
option for DF/DFF 280-660, DFFX 330-
660 and DF 2000
2-piece lter bowl standard for size

The total pressure drop of a lter at a
certain ow rate Q is the sum of the
housing Dp and the element Dp and is
calculated as follows:

3.1 Dp-Q HOUSING CURVES BASED
ON ISO 3968
The housing curves apply to mineral oil
with a density of 0.86 kg/dm³ and
a kinematic viscosity of 30 mm²/s.
In this case, the differential pressure
changes proportionally to the density.
