  Features

Features/Benefits

  • Solids removal from 1 to 1,700 microns.
  • Single system flow rates up to 3,000 gpm (681 m3/hr).
  • Broad selection of filter media materials and retentions suitable for a wide range of applications.
  • Smooth pipe and nozzle connection transitions to avoid dead spots in the the fluid stream and minimize pressure drop.
  • Numerous automated backwash option for operator-free service and minimal backwash effluent (<2% of system volume).
  • Available ACCUFLUX™ media dramatically increases filter surface area in the same footprint.
  • Proprietary 3-way, full-ported valves on AFC-1100 Multiplex Filters allow fast, frequent sequencing and maximum cleaning force during backwashing.
  • Isolated top-to-bottom backwash flow on AFC-1100 and AFC-3300 Multiplex Filters ensures complete and efficient media cleaning while continuing to deliver filtered product downstream.
  • Quick coupler valve connectors for ease of body tube removal.

The simple design and quick-element access of the AFC-Series Tubular Backwash Filter can significantly reduce the time and effort required to maintain, change elements and reconnect the unit’s valves.
