Type "R" return line filter elements to fit return line filter series NF, NFD, RF, RFD, RFL, RFLD, RFM. Installed in the return line, on top of or within the oil tank they filter the hydraulic oil before it flows back into the reservoir. This ensures that contamination arising in the components does not get into the tank.
HYDAC Return Line Filter elements maintain the targeted purity class like pressure filters. However, because of their arrangement, they do not fulfil the additional function of a protection filter. In contrast to a pressure filter, it only has to withstand low pressure levels
The 3 stage structure of the betamicron filter element ensures maximum contamination retention and filtration performance. An additional drainage layer directs the fluid flow with optimal efficiency, achieving particularly favourable Δp/Q characteristics. An innovative bonding process used for the longitudinal seam guarantees that the cut ends of the mesh pack remain completely sealed even under high load variations. This eliminates the possibility of particles crossing from the contaminated to the clean side. The metal tube which forms a stable core inside the element isconstructed as a spiral lock seam tube. This provides consistent stability and a significant reduction in element weight.
