Description:

Duplex filters of the series DNR 1001-8201 are suitable for a working pressure up to 16 bar.
Pressure peaks can be absorbed with a sufficient margin of safety.
Four mechanically connected change-over flaps enabling the change-over without service-interruption from the clean to the dirty filter-side.
The filters can be installed as suction filter, pressure filter or return-line filter.
The filter element consist of 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 direction is from outside to the inside. Filter finer than 40 μm should use throuw-away elements made of Interpor fleece (glass fibre). Filter elements as fine as 5 μm (c) are available; finer filter elements on request.
INTERNORMEN-Filter elements are known as elements with a high intrinsic stability and an excellent filtration capability, a high dirt-retaining capacity and a long service life.
INTERNORMEN-Filter are suitable for all petroleum based fluids, HW-emulsions, most synthetic hydraulic fluids and lubrication oils.
