3. FILTER CALCULATION /
SIZING
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.
