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 proteced 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.
› Filling filter/By-pass protection strainer:
The filling filter is integrated in the filter element and prevents
coarse particles from entering during filling or re-filling due to
maintenance or repair reasons. Filling can be carried out at the
filter. Therefore the cover must be removed. In operation, the
filling filter functions as a by-pass protection strainer and
prevents dirt from entering into the tank when the by-pass
valve is open.
› Port for ventilating filter:
The ventilating filter thread connection M42 x 2 allows
assembly of a ventilating filter, which assumes ventilation of
the tank. The ventilating filter has to be ordered separately.
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
Filter maintenance
By using a clogging indicator the correct moment for main-
tenance is stated and guarantees the optimum utilization of the
filter life.

› Extension pipe: A correct extension pipe length ensures oil
outlet below minimum oil level and prevents foaming.
Characteristics
Nominal flow rate
Return filter:
Up to 220 l/min (see Selection Chart, column 2). The nominal
flow rates indicated by ARGO-HYTOS are based on the following

› element service life > 1000 operating hours at an average
fluid contamination of 0,07 g per l/min flow volume

Filling filter:
up to 20 l/min (see Selection Chart, column 3)
Connection
Threaded ports according to ISO 228 or DIN 13.

The recommended starting viscosity can be read from the
diagram D (pressure drop as a function of the kinematic
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.
