It combines high-technology features with a service-friendly design for strong filtration value in both new pool and aftermarket installations. A durable glass-reinforced co-polymer tank handles demanding applications, including in-floor cleaning systems, and a heavy-duty tamper-proof one-piece flange clamp with self-aligning top and bottom gives quick access to internal components without disturbing piping. High-impact grid elements are designed for up-flow filtration and top-down backwashing for maximum efficiency, while integral lift handles and a uniform low-profile base make removing the grid nest fast and simple. An inlet diffuser elbow distributes unfiltered water evenly across all elements for even DE distribution, and 2-inch full-flow internal piping keeps flow resistance low. A quick quarter-turn air relief valve bleeds air fast.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVertical-grid DE design for superior clarity and large cleaning capacity\u003c\/li\u003e\n\u003cli\u003eGlass-reinforced co-polymer tank handles demanding applications, including in-floor cleaning systems\u003c\/li\u003e\n\u003cli\u003eHeavy-duty tamper-proof one-piece flange clamp with self-aligning top and bottom\u003c\/li\u003e\n\u003cli\u003eHigh-impact grid elements for up-flow filtration and top-down backwashing\u003c\/li\u003e\n\u003cli\u003eIntegral lift handles and low-profile base for fast grid-nest removal\u003c\/li\u003e\n\u003cli\u003eInlet diffuser elbow for even flow and DE distribution across all elements\u003c\/li\u003e\n\u003cli\u003e2 inch full-flow internal piping for low flow resistance\u003c\/li\u003e\n\u003cli\u003eRapid-release quarter-turn manual air relief valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: W3DE3620\u003c\/li\u003e\n\u003cli\u003eType: Vertical-grid DE (diatomaceous earth) pool filter\u003c\/li\u003e\n\u003cli\u003eEffective Filtration Area: 36 sq ft\u003c\/li\u003e\n\u003cli\u003eNumber of Grid Elements: 10\u003c\/li\u003e\n\u003cli\u003eDE Capacity: 4.5 lb\u003c\/li\u003e\n\u003cli\u003eDesign Flow Rate: 90 GPM residential, 72 GPM public\u003c\/li\u003e\n\u003cli\u003eApplication: In-ground\u003c\/li\u003e\n\u003cli\u003eTank: Glass-reinforced co-polymer (GFR), corrosion free\u003c\/li\u003e\n\u003cli\u003eInternal Piping: 2 inch full flow\u003c\/li\u003e\n\u003cli\u003eValve: Not included\u003c\/li\u003e\n\u003cli\u003eDimensions: 34.5 in H x 24 in x 24 in\u003c\/li\u003e\n\u003cli\u003eShipping Weight: 66 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":50006360064277,"sku":"W3DE3620-BSD","price":1389.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/9452\/6229\/files\/hayward-progrid-36-sq-ft-vertical-grid-de-pool-filter-w3de3620-padded.jpg?v=1784751572","url":"https:\/\/nationalpoolsupply.com\/products\/hayward-progrid-36-sq-ft-vertical-grid-de-pool-filter-w3de3620","provider":"National Pool Supply","version":"1.0","type":"link"}
