RF Series
In-Tank / Inline Filters
360 PSI • Up to 400 GPM
Features:
- RF 60 – 330 filters constructed of aluminum material. Aluminum alloy is water tolerant – anodization is not required for high water based fluids (HWBF).
- RF 660 – 1300 filters constructed of ductile iron.
- Non-welded housing design reduces stress concentrations prevents fatigue failure.
- Inlet/outlet port options include NPT, 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.
- Clogging indicators can be serviced without interruption of the hydraulic system.
- Single piece casting provides rigidity for inline or in-tank mounting.
