The exclusive Perflex Extended-Cycle gives you long filter cycles between cleaning – up to eight weeks depending on pool size and use. Because the same D.E. filter media is used over and over again, Perflex is a real work saver. And, it only takes minutes to extend the cycle.
Hayward Perflex Extended-Cycle Swimming Pool D.E. Filters clean swimming pools fast, removing particles as small as one micron the first time through. Its patented Flex-Tube design gives longer cycles between cleaning because the same D.E. filter powder is used over and over. Plus, Perflex cleans without backwashing, saving hundreds of gallons of treated pool water. An exceptional value as a replacement filter or for new pool installations. For sparkling, clean pools, step up to Perflex.

| Product Features

|
- Bump Handle – An exclusive Perflex feature. It activates the mechanism causing the Flex-Tubes to instantly and uniformly clean themselves of dirt and D.E. filter media.
-
- Flex-Tubes – The proven patented filter elements that efficiently reuse the D.E. filter media and dirt mixture forming a fresh filtering surface.
-
- Self Venting – As filtered water is returned to the pool, Perflex filters automatically expel any air that may be present in the system.
-
- Heavy Duty Filter Tank – Injection-molded of highstrength Polymer for dependable, corrosion-free performance.
-
- Combination Pressure Gauge and Threaded Inspection Service Port – Easy to read and remove when filter needs cleaning.
-
- Mixing Chamber – Engineered to produce a uniform, high velocity mixing of the D.E. filter media and dirt that is removed from the Flex-Tubes by Bumping .
-
- Check Valve – This integral valve automatically prevents system backflow whenever the pump is off.
-
- No Backwash – When conventional filters need backwashing, Perflex only needs Bumping . Bumping repositions the dirt within the filter so the flow of water is not impeded. This is called Regeneration, because flow and pressure are restored, extending the filter cycle. When the dirt-holding capacity of the Perflex filter is reached, cleaning is simple. Just Bump and drain.
