The Hayward W3DE4820 Pro-Grid 48 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 W3DE4820 uses a set or grids coated in pool grade diatomaceous earth. The set of grids consists of 7 full grids 24" in length and 1 partial grid 24" 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 W3DE4820 requires a minimum of 58.1" vertical clearance. Before removing the top lid, it is suggested to backwash the filter to discharge the contaminated DE powder.

Diatomaceous Earth (D.E.)
D.E. is a natural substance that captures dust, dirt and debris as small as 5 microns. A D.E. filter system removes body oils, suntan lotions, pollens, dust, and even some bacteria, making your swimming pool a healthier environment.
Energy Efficient
D.E. Filter systems cut energy costs by using lower pump pressure and speeds. If properly taken care of and rinsed regularly, they can significantly reduce water use. In addition to cost savings, lower pump pressure can help prolong the life of your pool pump!
Low Maintenance
A D.E. Filter maximizes the useful filtration area. A larger filtration area means longer periods between each cleaning, saving you time on pool maintenance and giving you more time to relax and enjoy your pool.
