Hayward EC75A Perflex® Extended Cycle D.E. Filter!
The Perflex Model EC75A is a high performance swimming pool filter with a filtration rating of 4,800 gallons per hour.
The EC75A filter uses diatomite filter powder (commonly called D.E.). D.E. is the most efficient dirt remover known. It is normally fed into the system through the skimmer when the filter is initially started; then drained from the filter when its dirt holding capacity has been reached. Through Perflexs exclusive BUMP action, the D.E. is periodically regenerated and the filter cycle extended without changing the powder. When the filter powder is totally used, the BUMP action makes it possible to drain the used diatomite without backwashing or dismantling the filter.
Perflex Extended-Cycle D.E. filters clean 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.
