Cleans without backwashing
Corrosion-free construction. Molded of attractive, high strength Duralon.
One Size for all pools. Easy to Install. Ideal for new or existing pools.
The Perflex filters use diatomaceous earth powder (commonly called D.E.). D.E. will remove particles as small as one micron and is the most efficient dirt remover known. It will remove microscopic dust and pollen.
Unfiltered water enters thru the bottom connection in the filter tank, flows upward thru the Flex-tubes and returns to the pool via the outlet in the filter head. When the filter is initially started. D.E. powder is is fed into the filtration system, usually thru the skimmer. This is called pre-coating. As the water passes thru the flex-tubes the filter powder is automatically coated on the outside of the filter-tubes, forming the working surface. As pool water passes thru the filter, the D.E. coating traps the contaminants, causing the filter pressure to rise. Normal filters would require backwashing to reduce the pressure. The Perflex only requires bumping. Backwash is only necessary, when bumping does not restore the normal flow.
