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. HDFF
lters (on request) are suitable for ow
in both directions.
Standard equipment:
port in L-conguration
without bypass valve
connection for a clogging indicator in
lter head
1.2 FILTER ELEMENTS
HYDAC lter elements are validated
and their quality is constantly
monitored according to the following
standards:
ISO 2941
ISO 2942
ISO 2943
ISO 3724

3. FILTER CALCULATION /
SIZING
The total pressure drop of a lter at a
certain ow rate Q is the sum of the
housing ∆p and the element ∆p and is
calculated as follows:

3.1 ∆p-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.

3.2 GRADIENT COEFFICIENTS (SK) FOR FILTER ELEMENTS
The gradient coefcients in mbar/(l/min) apply to mineral oils with a kinematic
viscosity of 30 mm²/s. The pressure drop changes proportionally to the change in
viscosity.
