RFM filters are constructed of polyamide plastic housing and lid. RFM 9///7 drop replacement for Tank Topper filters. alloy is water tolerant - anodization is not required for water based fluids (HWBF). The filter bowl on models 7-7 also serves as a contamination basket - removed to change element. Models,, 66, and 8 have filter elements equipped with separate, reusable contamination baskets. Cavities for clogging indicators are standard. NEW! s 7/9//6/8 available with - or -bolt tank flange.
