1.1 FILTER HOUSING
Construction
The filter housings are designed
in accordance with international
regulations. The two sections of the
filter housing with screw-on cover
plates are connected by means of a
ball change-over valve.
Standard equipment:
connections for venting and draining z
connection for a clogging indicator z
from size DN 80 the filters are fitted z
with a pressure equalisation line and
a ball shut-off valve
with bypass valve z
1.2 FILTER ELEMENTS

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

(*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.
