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.
