1.1 FILTER HOUSING
Construction
The filter housings are designed
in accordance with international
regulations. The two sections of the
filter housing (with screw-on cover
plates) are connected by means of a
ball change-over valve with negative
overlap and single lever operation
(ball, segment ) or hand-wheel
(butterfly).
Standard equipment:
connections for venting and draining z
connection for a clogging indicator z
pressure equalisation line z
with bypass valve z
1.2 FILTER ELEMENTS
Hydac filter elements are validated

3. FILTER CALCULATION /
SIZING
The total pressure drop of a filter at a
certain flow rate Q is the sum of the
housing ∆p and element ∆p and is
calculated as follows:
∆p
total
= ∆p
housing
+ ∆p
element
∆p

= (see point 3.1)

Sizing Program is available on request
free of charge.

3.1 ∆p-Q HOUSING GRAPHS BASED
ON ISO 3968
The housing graphs apply to mineral
oil with a density of 0.86 kg/dm
3
and a
kinematic viscosity of 30 mm
2
/s. In
this case, the differential pressure
changes proportionally to the density.
