EATON AFR Series Tubular Backwashing Filters

EATON AFR Series tubular backwashing filters features a unique, expandable circular design for increased capacity in a compact one-square-meter footprint. The Eaton AFR Series uses Ronningen-Petter technology for ideal for high volume, low viscosity applications with retentions as low as 2 microns.

EATON AFR High Performance & High Volume

Increased capacity and space saving:

  • Solids removal from 1 to 1,700 microns
  • Flow rates up to 2,000 gpm (454 m3/hr)
  • Broad selection of filter media materials and retentions suitable for a wide range of applications
  • Numerous automated backwash options for operator-free service and minimal backwash effluent (<2% of system volume)
  • Smooth pipe and nozzle connection transitions to avoid dead spots in the fluid stream and minimize pressure drop
  • Isolated top-to-bottom backwash flow for complete and efficient media cleaning while continuing to deliver filtered product downstream
  • Available ACCUFLUX™ media dramatically increases filter surface area in the same footprint
  • Configured with an array of up to eight – 4″ (101.8mm) or 6″; (152.4 mm) body tubes surrounding a central cleaning valve


  • Media-cleaning diffusers for more effective cleaning with low operating pressures or volumes
  • Drain header trap
  • Isolation butterfly valves for individual body tube removal while filter is in operation
  • Hinge-lock quick couplings
  • 304 stainless steel frame material

Cost reduction:

  • A single AFR Series filter can replace a 13- station multiplexed system.
  • For even higher flow rates, AFR Series filters can be easily combined.
