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
housing
= (see point 3.1)
∆p
element
=Q• SK* •viscosity

(*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 coefficients in mbar/(l/min) apply to mineral oils with a kinematic
viscosity of 30 mm

viscosity.
