Hayward W3EC40AC Perflex® D.E Filter w/ Clamp 4 lb.

Hayward W3EC40AC PerFlex® D.E. Filter with Clamp – 4 lb Capacity

The Hayward PerFlex® W3EC40AC is an extended-cycle D.E. filter designed to deliver high-efficiency filtration for residential swimming pools. Built with Hayward’s patented Flex-Tube technology, this filter captures extremely small debris particles while maintaining strong water flow throughout the system.

Unlike traditional filters that require backwashing, the PerFlex system uses a bump handle mechanism to purge accumulated debris from the Flex-Tube elements. This helps extend filtration cycles while conserving pool water and reducing maintenance time.

Compact High-Efficiency Pool Filtration

The PerFlex clamp-style design allows easy access for servicing and cleaning. Its durable thermoplastic tank construction and efficient filtration design make it a dependable option for maintaining clear pool water in both above-ground and smaller in-ground pool systems.
