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

Options:

• 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.
