When using electrical clogging
indicators, the electrical power supply
to the system must be switched off
before removing the clogging indicator
connector.

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 the element ∆p and is
calculated as follows:
∆p

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 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 coefcients 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.
