RFD Series
In-Tank / Inline Duplex Filters
360 PSI • Up to 400 GPMFeatures
- RFD 60 – 330 filters are constructed of aluminum.
- Aluminum alloy is water tolerant – anodization is not required for water based fluids (HWBF).
- RFD 660 – 1300 filters are constructed of ductile iron.
- Non-welded housing design reduces stress concentrations and prevents fatigue failure.
- Inlet/outlet port options include NPT (RFD 61-241 inlet only), SAE straight thread O-ring boss, and SAE 4-bolt flange to allow easy installation without costly adapters.
- Bolt-on lid requires minimal clearance for removal.
- O-ring seals are used to provide positive, reliable sealing. Choice of O-ring materials (Nitrile, Fluoroelastomer, EPDM) provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water base fluids.
- Reusable contamination basket prevents loss of retained contaminants into the reservoir during element replacement.
- All RFD duplex filters have a ball-type selector valve to provide continuous filtration without system shut-down to change clogged elements.
