It uses diatomaceous earth, the most effective filter media available, to remove even the smallest particles on the first pass. Its patented Flex-Tube design reuses the DE and dirt mixture to continuously form fresh cleaning surfaces, giving extended filter cycles with no backwashing required. An exclusive bump handle activates the Flex-Tubes so they instantly purge themselves of dirt and powder, and a combination diffuser and lower mixing chamber produces a uniform DE coating on the tubes. The system is also designed to expel any trapped air back through the filtered water returning to the pool, and an easy-access clamp assembly makes service simple.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLargest capacity in the Perflex line\u003c\/li\u003e\n\u003cli\u003eUses DE, the most effective filter media, for superior water clarity\u003c\/li\u003e\n\u003cli\u003eRemoves even the smallest particles on the first pass\u003c\/li\u003e\n\u003cli\u003ePatented Flex-Tube system reuses DE to form fresh cleaning surfaces\u003c\/li\u003e\n\u003cli\u003eExclusive bump handle instantly purges the tubes of dirt and powder\u003c\/li\u003e\n\u003cli\u003eExtended filter cycles with no backwashing required\u003c\/li\u003e\n\u003cli\u003eCombination diffuser and mixing chamber for a uniform DE coating\u003c\/li\u003e\n\u003cli\u003eExpels trapped air back through the filtered water return\u003c\/li\u003e\n\u003cli\u003eEasy-access clamp assembly for simple service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: W3EC75A\u003c\/li\u003e\n\u003cli\u003eType: Extended-cycle DE (diatomaceous earth) pool filter\u003c\/li\u003e\n\u003cli\u003eEffective Filtration Area: 40 sq ft\u003c\/li\u003e\n\u003cli\u003eNumber of Elements: 1 (Flex-Tube nest)\u003c\/li\u003e\n\u003cli\u003eDE Capacity: 7 lb\u003c\/li\u003e\n\u003cli\u003eDesign Flow Rate: 100 GPM residential, 80 GPM public\u003c\/li\u003e\n\u003cli\u003eApplication: In-ground\u003c\/li\u003e\n\u003cli\u003eDimensions: 31 in H x 21 in x 21 in\u003c\/li\u003e\n\u003cli\u003eShipping Weight: 45 lb\u003c\/li\u003e\n\u003cli\u003eWarranty: 1 year parts\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":50006362226965,"sku":"W3EC75A-BSD","price":1239.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/9452\/6229\/files\/Basic_Modular_Filter_W3EC75A_LEFT_2477_Large_a3359fa3-39dd-47bd-befa-5a80e69f44ed.png?v=1783360375","url":"https:\/\/nationalpoolsupply.com\/products\/hayward-perflex-extended-cycle-40-sq-ft-de-pool-filter-w3ec75a","provider":"National Pool Supply","version":"1.0","type":"link"}
