The Hayward W3DE3620 Pro-Grid 36 sq. ft. D.E. Pool Filter provides the highest level of filtration. The Hayward Pro-Grid is capable of filtering out particulate as small as 5 microns. That's the same size as a human red blood cell.

The Hayward Pro-Grid W3DE3620 uses a set of grids coated in pool-grade diatomaceous earth. The set of grids consists of 7 full grids 18" in length and 1 partial grid 18" in length. The Pro-Grid tank is made with glass-reinforced thermoplastic that enhances durability and product life. It uses a manual air relief valve that eliminates air buildup in the tank rather than having it force back thru the system.

A 1-1/2" drain is used for quick drainage, and a one-piece flange clamp rests securely around the tank, securely fastening each half tightly together. To remove the W3DE3620 requires a minimum of 50.1" vertical clearance. Before removing the top lid, it is suggested to backwash the filter to discharge the contaminated DE powder.

  • Filter tanks are made from the most durable materials to meet the demands of the toughest applications and environmental conditions
  • High capacity, rapid release manual air relief valve bleeds air with a quick quarter turn of the lever
  • Heavy-duty, tamper-proof, one-piece flange clamp securely fastens tank top and bottom and allows quick access to all internal components
  • Please Note: Valve is sold separately
  • Compatible with valves: SP0740DE (Selecta-Flo 2" SKT), SP0710XR50 (Vari-Flo 1 1/2" NPT), SP0715XR50 (Vari-Flo 2" NPT - Optional), SP0410X5025 (Slide Valve 2" SKT - Optional)
