Hayward EC65A Perflex Extended-Cycle DE Filter; 27 sq-ft, 67 gpm

Perflex extended-cycle diatomaceous earth (DE) filters provide superior water clarity and extended filter cleaning cycles without requiring backwashing.

Pool Filter Feature

  • Bump handle activates the mechanism causing the Flex-Tubes to instantly and uniformly clean themselves of dirt and DE filter media
  • The proven patented filter elements that efficiently reuse the DE filter media and dirt mixture forming a fresh filtering surface
  • Heavy duty filter tank is injection-molded of high strength polymer for dependable, corrosion-free performance
  • Self venting - as filtered water is returned to the pool, Perflex filters automatically expel any air that may be present in the system
  • Combination pressure gauge and threaded inspection/service port are easy to read and remove when filter needs cleaning
  • Mixing chamber engineered to produce a uniform, high velocity mixing of the DE filter media and dirt that is removed from the Flex-Tubes by "Bumping"
  • Integral check valve automatically prevents system backflow whenever the pump is off
  • Clean pools fast, removing particles as small as two microns the first time through.
  • Patented Flex-Tube design gives longer cycles between cleaning because the same D.E. filter powder is used over and over
  • Unique bump mechanism allows DE flex tubes to instantly and uniformly clean themselves of dirt and DE filter media
