Description
Characteristics
Ventilating Filter
Ventilation of the reservoir by an integral star-shape pleated filter element:
• removable (replace annually!)
• splash-proof
• neness 2 µm
Filter maintenance
By using a clogging indicator the correct moment for maintenance is stated
and guarantees the optimum utilization of the filter life.
Materials
Screw-on cap: Polyester, GF reinforced
Housing: Polyamide, CF reinforced, electrically conducting
Seals: NBR (FKM on request)
Filter media: EXAPOR
®
MAX 2 - inorganic multi-layer microbre web
Paper - cellulose web, impregnated with resin
Accessories
Electrical and optical clogging indicators are available on request.
Dimensions and technical data see catalog sheet 60.20.
Recommended hose clamps according to DIN 3017 Part 2 or equivalent for
hose OD 0.91 inch or 1.02 inch. For orders use ARGO-HYTOS Part No. 332
70 03 or 332 70 04.
Extension pipes on the bowl outlet are available in several lengths on request.
A self-assembly system for installation of extension pipes can be ordered.
For detailled information please see catalog sheet 20.390.
Application
In the return line circuits of hydraulic systems.
Performance features
Protection
against wear: By means of lter elements that, in full-ow ltration,
meet even the highest demands regarding cleanliness
classes.
Protection against
malfunction: By means of full-ow ltration 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
Connection: Hose nipple
By-pass valve: The location close to the inlet port prevents dirt particles
retained by the lter element from entering into the clean
oil side.
Removable bowl: In case of maintenance the lter bowl is removed
together with the lter element - therefore dirt particles
are not ushed back into the tank.
Oil separator: Prevents oil splashing through the breather on mobile
application.
Extension pipe: A correct extension pipe length ensures oil outlet below
minimum oil level and prevents foaming.
Filter elements
Flow direction from outside to center. The star-shaped pleating of the lter
material results in:
• large lter surfaces
• low pressure drop
• high dirt-holding capacities
• long service life
Hydraulic fluids
Mineral oil and biodegradable uids
(HEES and HETG, see info-sheet 00.20).
With high lling conditions we recommend
an electrical conductivity >_ 500 pS/m at 68 °F.
Temperature range
- 22 °F ... + 176 °F (short intervals to + 212 °F)
Viscosity at nominal flow rate
• at operating temperature: ν < 280 SUS
• as starting viscosity: ν
max
= 5560 SUS
• at initial operation: 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 inter-
sects the ∆p curve at a point. Read this point
on the horizontal axis for the viscosity.
Operating pressure
Max. 87 psi
Mounting position
Preferably vertical, outlet downwards
Nominal flow rate
Up to 18.5 gpm (see Selection Chart, column 2)
The nominal ow rates indicated by ARGO-HYTOS are based on the
following features:
• closed by-pass valve at ν ≤ 930 SUS
• element service life > 1,000 operating hours at an average
uid contamination of 0.27 g per gpm ow volume
• ow velocity in the connection lines ≤ 14.8 ft/s
Connection
Hose nipple for hose up to ID ¾ inch.

Selection Chart
As clogging indicators either manometers or electrical pressure switches can be used. Optional extension pipes adapt the lter length to various tank
depths. For ordering of accessories please use the below mentioned codes.
Order example: The filter FR 072-276 has to be supplied with an extension pipefor a mounting depth of 500 mm (resp. 19.69 inch).
Order description: FR 072-276 / EV 500

The functions of the complete lters as well as the outstanding features
of the lter elements assured by ARGO-HYTOS can only be guaranteed if
original ARGO-HYTOS spare parts are used.
Quality management according to DIN EN ISO 9001
To ensure constant quality in production and operation, ARGO-HYTOS
lter elements undergo strict controls and tests according to the following
ISO standards:
ISO 2941 Verication of collapse/burst pressure rating
ISO 2942 Verication of fabrication integrity (Bubble Point Test)
ISO 2943 Verication of material compatibility with uids
ISO 3968 Evaluation of pressure drop versus ow characteristics
ISO 16889 Multi-Pass-Test (evaluation of lter neness and
dirt-holding capacity)
ISO 23181 Determination of resistance to ow fatigue using high
viscosity uid
Various quality controls during the production process guarantee the
leakfree function and solidity of our lters.
Our engineers will be glad to advise you in questions concerning lter application, selection as well as the cleanliness class of the ltered medium attainable
under practical operating conditions.
