Perflex EC 40 DE Filter

Achieve the absolute highest standard of water clarity with the Hayward Perflex EC40 Extended-Cycle D.E. Filter Tank. Diatomaceous Earth (D.E.) is widely recognized as the most effective pool filtration medium available, trapping microscopic dust, pollen, and debris down to 1 micron—well beyond the capabilities of standard sand or cartridge filter systems. Designed as a high-performance replacement tank for above-ground and small inground pools, this unit delivers sparkling, polished pool water with minimal operational effort.

Patented Flex-Tube™ Extended-Cycle System

The core of the EC40 filter is engineered around Hayward's exclusive performance-matched design. By utilizing a series of specialized internal flex-tubes, it creates a highly uniform screening surface that reuses the D.E. powder and dirt mixture efficiently. This unique design produces less backpressure and flow resistance than conventional units, allowing your existing pool pump to circulate more water with less horsepower.

Exclusive Bump Handle Regeneration

Say goodbye to traditional multi-port valve backwashing and heavy water waste. The EC40 features an integrated, easy-to-use bump mechanism at the top of the tank. When the pressure gauge indicates dirt accumulation, a simple manual activation of the bump handle instantly cleans the flex-tubes and repositions the D.E. cake, extending your filtration cycles without expelling treated water down the drain.
