Hayward Flow Controller for Perflex DE Filters, ECX1055

The Hayward ECX1055 is the flow controller used inside Perflex and ReGenX DE filters. It is the genuine Hayward part and is made in metal.

Fitment, and a caution

The description Hayward carries for this item names the Perflex EC40 and EC50 filters and the ReGenX RG450. The parts drawings the controller appears on are broader, covering the Perflex EC30 and EC40, the EC50, EC50C, EC50A and EC50AC, and the ReGenX. The two lists do not match exactly, so identify your filter model and check it against the Hayward drawing rather than ordering on the short description alone.

What to expect

Hayward notes that the color of the supplied part may vary from the photograph. That is a cosmetic difference only. Because the controller is an internal component, plan the job around opening the filter: shut down and depressurize the system, relieve the air, and have any seals you disturb on hand before you start.
