1.1 FILTER HOUSING
Construction
The lter housings are designed
in accordance with international
regulations. They consist of one-piece
housings with bolt-on cover plates.
The two housings are connected by a
ball change-over valve with negative
overlap and single-lever operation.
Standard equipment:
with bypass valve z
connection for a clogging indicator z
(1 clogging indicator per lter side)
1.2 FILTER ELEMENTS

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 element ∆p and is
calculated as follows:
∆p
total
= ∆p
housing
+ ∆p
element
∆p
housing
= (see point 3.1)
∆p
element
= Q • SK* • viscosity
1000 30
(*see point 3.2)
For ease of calculation, our Filter
Sizing Program is available on request
free of charge.
NEW: Sizing online at www.hydac.com
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.
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 mm
2
/s. The pressure drop changes proportionally to the change in
viscosity.
