4. Description:
Return-line filters in the TEFB series are suitable for a working pressure up to 10 bar.
Pressure peaks will be absorbed by a sufficient margin of safety. The TEFB-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 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 throw-away elements made of
paper or Interpor fleece (glass fibre). 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. Con-
sult 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.

4. 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 mar-
gin 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 bon-
ded to the end caps with a high-quality adhesive. The flow is from outside to inside. Filters finer than 40 µm should use throw-away ele-
ments made of paper or Interpor fleece (glass fibre). 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 ca-
pacity, 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.

Return-line filters change-over in the DTEF series are suitable for a working pressure up to 10 bar. Pressure peaks will be absorbed by a sufficient
margin of safety. The DTEF-filters are directly mounted to the reservoir and connected to the return-line.

3. Description:
Return-line filters change-over in the DTEF series are suitable for a working pressure up to 10 bar. Pressure peaks will be absorbed by a sufficient
margin of safety. The DTEF-filters are directly mounted to the reservoir and connected to the return-line.
A three-way-change-over valve which is integrated in the middle of the housing makes it possible to switch from the dirty filter-side to the clean
filter-side without interrupting operat ion.
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 throuw-away elements made of
paper or Interpor fleece (glass fibre). 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.

4. Description:
Return-line filters change-over in the DTEF series are suitable for a working pressure up to 10 bar. Pressure peaks will be absorbed by a sufficient
margin of safety. The DTEF-filters are directly mounted to the reservoir and connected to the return-line.
A rotary slide valve which is integrated in the middle of the housing makes it possible to switch from the dirty filter-side to the clean filter-side
without interrupting operat ion.
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 throuw-away elements made of paper
or Interpor fleece (glass fibre). 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.
