Description:

Return-line filters in the TEF series are suitable for a working pressure up to 10 bar.
Pressure peaks will be absorbed by a sufficient margin of safety.
The TEF-filters are directly mounted to the reservoir and connected to the return-line.
The filter element consists of a star-shaped, pleated filter material which is supported on the inside by a perforated core tube and is bonded 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. 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.
