Description
Characteristics
Filter maintenance
By using a clogging indicator the correct moment for maintenance is stated and
guarantees the optimum utilization of the filter life.
Materials
Filter head cover: Aluminium alloy
Filter head: Aluminium alloy
Filter bowl: Steel
Seals: NBR (FPM on request)
Filter media: EXAPOR
®
MAX 2 - inorganic multi-layer microfibre web
Paper - cellulose web, impregnated with resin
Stainless steel wire mesh (1.4301)
Accessories
Extension pipes and diffusers are available on the bowl outlet.
Extension pipe: A correct extension pipe length ensures oil outlet below
minimum oil level and prevents foaming.
Diffuser: Diffusers reduce oil velocity and direct the oil to 90°
outlet flow. This function prevents also oil foaming and
whirling up of solid particles settled at the tank bottom.
The mesh screen element filters the oil in case of an open
by-pass valve.
Electrical and optical clogging indicators are available on request.
Dimensions and technical data see catalogue sheet 60.20.
Application
In the return line circuits of hydraulic systems.
Performance features
Protection
against wear: By means of filter elements that, in full-flow filtration,
meet even the highest demands regarding cleanliness
classes.
Protection against
malfunction: By means of full-flow filtration in the system return,
the pumps above all are protected from dirt particles
remaining in the system after assembly, repairs, or which
are generated by wear or enter the system from outside.
Special features
By-pass valve: The location close to the inlet port prevents dirt
particles retained by the filter element from entering
into the clear oil side.
Removable bowl: In case of maintenance the filter bowl is removed
together with the filter element - therefore dirt particles
are not flushed back into the tank.
Filter elements
Flow direction from outside to centre. The star-shaped pleating of the filter
material results in:
• largeltersurfaces
• lowpressuredrop
• highdirt-holdingcapacities
• longservicelife
In filters with a magnetic system, the ferromagnetic particles in the fluid
pass first through a strong magnetic field and are separated.

Spare Parts
Quality Assurance
Quality management according to DIN EN ISO 9001
To ensure constant quality in production and operation, ARGO-HYTOS
filter elements undergo strict controls and tests according to the following
ISO standards:
ISO 2941 Verification of collapse/burst pressure rating
ISO 2942 Verification of fabrication integrity (Bubble Point Test)
ISO 2943 Verification of material compatibility with fluids
ISO 3968 Evaluation of pressure drop versus flow characteristics
ISO 16889 Multi-Pass-Test (evaluation of filter fineness and
dirt-holding capacity)
ISO 23181 Determination of resistance to flow fatigue using high
viscosity fluid
Various quality controls during the production process guarantee the
leakfree function and solidity of our filters.
Our engineers will be glad to advice you in questions concerning filter application, selection as well as the cleanliness class of the filtered medium attainable
under practical operating conditions.
