SPECIFICATIONS
1.1 FILTER HOUSING
Construction
The lters consist of a spin-on lter
can which screws onto a connection
tube which is tted to the oil tank.
The connection can either be a
anged or weld version.

3. FILTER CALCULATION /
SIZING
3.1 SINGLE PASS FILTRATION
PERFORMANCE DATA FOR AIR
FILTER ELEMENTS
The following separation values were
established under real-life simulated
conditions.
This means that the selected velocity
of the ow against the lter mesh-pack
was 20 cm/s and the contamination
added was 40 mg/m³ of ISO MTD test
dust.
Filtration Retention For particle Filter
rating value d... size material
10 µm d 80 0.25 µm
d 100 0.84 µm
BN
20 µm d 80 0.36 µm
d 100 1.21 µm
10 µm d 80 1.49 µm
P
d 100 9.56 µm
The d 80 value refers to the particle
size which is ltered out at a rate
of 80% during the retention test.
The particle size determined by this
method is called the nominal ltration
rating of the air lter. The d 100
value therefore refers to the particle
size which is ltered out at a rate of
100% during the single pass test.
The particle size determined by this
method is called the absolute ltration
rating of the air lter.

3.4 AIR FLOW RATE
3.3 SIZING GUIDELINES
The rate at which contamination enters
a hydraulic system can be considerably
reduced by using efcient tank breather
ltration.
CAUTION:
Incorrectly sized tank breather lters
can place additional strain on the
system and reduce the service life of
hydraulic lter elements.
For optimum sizing the following
should therefore be observed:
Filtration rating of breather lter ≤
ltration rating of hydraulic lter
Only use breather lters with an
absolute retention rate (d100≤ x µm;
x = given ltration rating)
Max. permitted initial pressure drop:
0.01 bar (with a clean lter element
and at calculated air ow)
