In-Tank Return Line Filters PSI up to GPM Hydraulic Symbol: INLET INLET Bypass Valve Pop-up Breather Bypass Valve Pop-up TANK OUTLET TANK OUTLET TANK OUTLET 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 replacement for Tank Topper filters. Aluminum 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. Applications: Agricultural Industrial Pulp & Paper Automotive Offshore Railways Construction Commercial Municipal Shipbuilding Gearboxes Power Generation Steel / Heavy Industry Technical Details: Mounting Method 7/9//6/8 mounting holes - filter housing /7///66/8 mounting holes - filter housing Port Connections Inlet Outlet / NPT.7 Smooth Port 9/ SAE- Hose Barb 7/6/8 SAE-6.6 Smooth Port /7 SAE- Open Bottom / SAE- NPT / SAE Flange, Code 6 NPT 66/8 / SAE Flange, Code 6 G / BSPP Direction of Flow Side inlet and bottom outlet.
