HYDRAULIC AND LUBE OIL FILTERS RFM Series Low Pressure In-Tank Return Line Filters psi up to gpm Technical Details Mounting Method 7/9///8 mounting holes - filter housing Features The compact and lightweight design make RFM filters especially suitable for mobile applications. RFM filters are constructed of polyamide plastic housing and lid. RFM 9///7 drop in replacement for Tank Topper filters. s 7-8 aluminum alloy is water tolerant - anodization is not required for water based fluids (HWBF). The filter bowl on models - 7 also serves as a contamination basket - removed to change element. Models,,, and 8 have filter elements equipped with separate, reusable contamination baskets. Cavities for clogging indicators are standard. s 7/9///8 available with - or -bolt tank flange. s 97 & added for increased flow capacities they also utilize separate bypass assemblies Applications Hydraulic Symbol RFM s 97 & coming in Agricultural Automotive Construction A T T A T /7/9///8//7/ ///8/97/ Port Connections 9/ 7//8 /7 / /8 97/ Direction of Flow Inlet / Outlet mounting holes - filter housing SAE-8 /.9 SAE- / SAE- /.
