EATON F Series Tubular Backwashing Filters

Eaton F Series Tubular Backwash Filters features a modular design that enables future capacity and configuration flexibility. It also uses cleanable media that reduces life cycle costs and maximizes productivity.

Features of the Eaton F Series Tubular Backwash Filters

  • For liquid filtering applications that require unattended operation, maximum uptime, and solids removal from 1 to 1,700 microns, the F-Series family of filter systems delivers unbeatable performance.
  • Versatility with a modular design that enables future capacity and configuration flexibility.
  • Single system flow rates up to 3,000 gpm (681 m3/hr).
  • Smooth pipe and nozzle connection transitions to avoid dead spots in the fluid stream and minimize pressure drop.
  • A broad selection of filter media materials and retentions suitable for a wide range of applications.
  • Proprietary 3-way, full-ported valves allow fast, frequent sequencing and maximum cleaning force during backwashing.
  • Isolated top-to-bottom backwash flow ensures complete and efficient media cleaning while continuing to deliver filtered product downstream.
  • Numerous automated backwash options for operator-free service and minimal backwash effluent (<2% of system volume).
  • Available ACCUFLUX® media dramatically increases filter surface area in the same footprint.




3-Way Ball Valves
To ensure positive sealing and maximum flow, our F-Series filters feature the industry’s best 3-way ball valves. These important components— designed and manufactured by Eaton exclusively for Eaton systems—were developed specifically for the demands of industrial filtration. Their full-ported design reduces pressure drop and requires no additional linkages for actuation.



  • Internal or external backwashing
  • Media-cleaning diffusers for more effective cleaning at low operating pressures or volumes
  • Drain header trap
  • Quick coupler valve connectors for ease of body tube removal
  • 304 stainless steel frame material
  • ASME code vessels

How the EATON F Series Works

When cleaning is required, triggered by time or pressure differential, a single valve removes the tube to be backwashed from the incoming flow stream. The resulting pressure drop redirects a portion of the clean process flow downward, flushing the contaminants to the drain manifold. When process liquids are very valuable or hazardous, an external back-wash configuration, which uses a small amount of cleaning liquid introduced through a separate manifold, is recommended. External backwashing is also recommended when operating pressures are expected to be less than 45 psi (3.1 bar).
