Description
Filter elements are used to protect hydraulic elements against contaminations. They are installed e.g. in front of valves and intensifiers and avoid penetration of swarf and contamination. Thereby the safety of functioning as well as the life are considerably increased.
Up to their complete clogging all filters are pressure stable up to the max. operating pressure and due to their stainless steel version they can be used also for water and other liquids as e.g. cooling lubricants (except 3887-030).

High-pressure filter with rectifier function (figure 1 and 2)
This new high-pressure filter with rectifier function has been designed to protect high-quality hydraulic components. With the unique rectifier function this filter is perfect for all systems where operating stroke and
return stroke are effected through one line (e.g. clamping and unclamping line in a hydraulic fixture).
The filter element is flown through always in one direction during the operating stroke as well as during the return stroke. This implies safe removal of contaminations and thereby optimum protection of high-quality components.

These very long-life filter elements can be cleaned. There are no high follow-up costs.
Due to its compact design, this filter can be mounted in nearly every system and is also perfectly suitable for retrofitting.
The filter can be integrated in the hydraulic circuit via fittings and pipes or drilled channels and O-ring connection.
The filter insert can be taken out at the side and be cleaned without opening the hydraulic circuit.
