RFM Series
In-Tank Return Line Filters
145 PSI • Up to 224 GPM
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 90/150/210/270 drop replacement for “Tank Topper” filters.
- Aluminum alloy is water tolerant – anodization is not required for water based fluids (HWBF).
- The filter bowl on models 75 – 270 also serves as a contamination basket – removed to change element.
- Models 30, 330, 500, 661, and 851 have filter elements equipped with separate, reusable contamination baskets.
- Cavities for clogging indicators are standard.
