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 or 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.
