1. TECHNICAL
SPECIFICATIONS
1.1 FILTER HOUSING
Construction
The lters consist of a spin-on can
which screws onto a connection tube
which is tted to the oil tank.
The connection can either be a ange,
weld or threaded version.
1.2 FILTER CARTRIDGES
The lter cartridges comply with all
relevant ISO test criteria.
1.3 SEALS
Cardboard for ange model.
1.4 SPECIAL MODELS AND
ACCESSORIES

1.8 COMPATIBILITY WITH
HYDRAULIC FLUIDS ISO 2943
The tank breather lter/dehumidier
BLT is suitable for use with all
standard mineral and lubrication oils.
1.9 CHANGING INTERVALS
The lter elements or lters must be
replaced as frequently as the uid
lters, but at least every 6 months.

3. FILTER CALCULATION /
SIZING
Differential pressure across breather
lter
The differential pressure in the clean
condition is shown in the graph below.
3.1 SIZING GUIDELINES
The rate at which contamination and
humidity 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)
