Return Filters
Description
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 clean 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.
› Extension pipe:
A correct extension pipe length ensures oil outlet below
minimum oil level and prevents foaming.
Filter elements
Flow direction from outside to centre. The star-shaped pleating
of the filter material results in:
› large filter surfaces
› low pressure drop
› high dirt-holding capacities
› long service life
Ventilating Filter
Ventilation of the reservoir by an integral star-shape pleated filter
element:
› removable (replace annually!)
› splash-proof
› fineness 2 µm
Filter maintenance
By using a clogging indicator the correct moment for main-
tenance is stated and guarantees the optimum utilization of the
filter life.

viscosity) as follows: Find the 70 % ∆p of the cracking
pressure of the by-pass valve on the vertical axis. Draw a
horizontal line so that it intersects the ∆p curve at a point.
Read this point on the horizontal axis for the viscosity.

The functions of the complete filters as well as the outstanding
features of the filter elements assured by ARGO-HYTOS can only
be guaranteed if original ARGO-HYTOS spare parts are used.
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.
Illustrations may sometimes differ from the original. ARGO-HYTOS is not responsible for any unintentional mistake in this specification sheet.
