Return Line Filter

Return Line Filters - Type RTF1025
STAUFF RTF1025 Return Line Filters are designed as tank top filters with a maximum operating pressure of 3,4 bar 49 PSI.
Return Line Filters - Type RTF20
STAUFF RTF20 Return Line Filters are designed as tank top filters with a maximum operating pressure of 10 bar 145 PSI and flow rates up to 115 lmin 30 US GPM. The filter bowl is designed to return the oil beneath the surface thus preventing entrainment of air. RTF20 series compact design and integral breather make them ideal for mobile hydraulic applications.
Return Line Filters - Type RTF40
STAUFF RTF40 Return Line Filters are designed as tank top filters with a maximum operating pressure of 6,9 bar 100 PSI. The filter bowl is designed to return the oil beneath the surface thus preventing entrainment of air. The Filter Elements RTE-48 interchange with the popular “K” series and Filter Elements RTE-49 interchange with the“RE-409” series elements.
Return Line Filters - Type RTF50
STAUFF RTF50 Return Line Filters are designed for tank top applications with a maximum pressure of 6,9 bar 100 PSI. The fi lter bowl is designed to return the oil beneath the surface thus preventing entrainment of air. The Filter Elements RTE-58 interchange with the popular “K” series and Filter Elements RTE-59 interchange with the“RE-409” series elements.
