High Pressure Filters

High Pressure Filters

HD 069 (High Performance)

Description
Application
In the high pressure circuits of hydraulic systems.
Performance features
Protection against wear:
By means of fi lter elements that even in full-fl ow fi ltration meet
the highest demands regarding cleanliness classes.
Protection against malfunction:
Through installation near to the control valves or other expensive
components. The specifi c determined fl ow rate guarantees a
closed by-pass valve even at ≤ 200 mm2
/s / 927 SUS (cold start
condition).
Filter elements
Flow direction from outside to center.
The star-shaped pleating of the fi lter material results in:
› large fi lter surfaces
› low pressure drop
› high dirt-holding capacities
› long service life
Filter maintenance
By using a clogging indicator the correct moment for maintenance is stated and guarantees the optimum utilization of the
fi lter life.

Accessories
Electrical and / or optical clogging indicators are available on
request. Dimensions and technical data see catalog sheet 60.40.

Nominal flow rate
Up to 105 l/min / 27.7 gpm (see Selection Chart, column 2)
The nominal flow rates indicated by ARGO-HYTOS are based on
the following features:
› closed by-pass valve at ν ≤ 200 mm2
/s / 927 SUS
› element service life > 1000 operating hours at an average
fluid contamination of 0.07 g per l/min / 0.27 g per gpm
flow volume
› flow velocity in the connection lines:
up to 250 bar ≤ 8 m/s / up to 3626 ≤ 26.3 ft/s
> 250 bar ≤ 12 m/s / > 3626 ≤ 39.4 ft/s
