Hydraulic return filter
max. 10 bar | RF 210-320 INTERNORMEN Technology

Return-line filters RF 210-320 are designed for connection in return pipes. The feed pressure at „IN“ connections can be pressurized to 10 bar. The return pipes at the „OUT“ connection must be < 1m long. The pressure in the return pipe is added to the differential pressure over the filter element and must be considered when consulting the contamination indicator.
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 microns 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-Filter elements are known as elements with a high intrinsic stability and an excellent filtration capability, a high dirtretaining capacity and a long service life.
INTERNORMEN-Filter can be used with mineral oils, bio-oils, emulsions and most synthetic hydraulic fluids and lubricating oils.
During changing of the filter element care should be taken to ensure that the contaminated side of the filter is emtied before the filter is removed, to ensure that no contaminated liquid enters the discharge pipes. After depressurizing the filter or emptying the contaminated side of the filter and removing the filter cover, the element should be removed by the wire strap and a new element fitted.
Disposal of the contaminated fluid removed from the filter must be carried out in accordance with national regulations.
