Description:

Return-line filters in the TEFB series are suitable for a working pressure up to145 PSI.
Pressure peaks will be absorbed by a sufficient margin of safety. TheT EFB-filters are directly mounted to the reservoir and connected to the return-line. No connection is needed for the build-in air filter. The air filter has a 10 μm throw-away element.
The filter element consists of a star-shaped, pleated filter material which is supported on the inside by a perforated core tube and isbonded to the end caps with a high-quality adhesive. The flow is from outside to inside. Filters finer than 40 μm should use throwaway elements made of paper or Interpor fleece (glass fiber). Filter elements as fine as 5 μm(c) are available; finer filter elements on request.
INTERNORMEN-Filters can be used for petroleum-based fluids, HW emulsions, water glycols, most synthetic fluids and lubrication fluids. Consult factory for specific fluid applications.
INTERNORMEN-Filters elements are known as stable elements which have excellent filtration capabilities and a high dirt retaining capacity, therefore having a long service life. Due to its practical design, the return-line filter is easy to service.
When changing the filter element a detachable connection between the filter head and the filter bowl prevents a flow back of dirty oil into the tank.
