Features

N/A

  • RF 30 filters are constructed of polyamide plastic.
  • RF 60 - 330 filters are constructed of aluminum material. Aluminum alloy is water tolerant - anodization is not required for high water based fluids (HWBF).
  • RF 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, SAE straight thread O-ring boss, and SAE 4-bolt flange to allow easy installation without costly adapters.
  • O-ring seals are used to provide positive, reliable sealing. Choice of O-ring materials (nitrile rubber, fluorocarbon elastomer, ethylene propylene rubber) provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water base fluids.
  • Bolt-on lid requires minimal clearance for removal.
  • Reusable contamination basket prevents loss of retained contaminants into the reservoir during element replacement.
  • Single piece casting provides rigidity for inline or in-tank mounting.

Application

N/A

  • Agricultural
  • Automotive
  • Construction
  • Gearboxes
  • Industrial
  • Steel/Heavy Industry

Note

N/A This filter is configured with an ..... R .... type (return/low pressure) element, so if the filter requires a bypass, the bypass is located in the closed end cap of the cartridge element.
