Pro-Grid™ vertical grid D.E. filters provide superior water clarity, efficient flow and large cleaning capacity for pools and spas of all types and sizes. Constructed with high-strength reinforced thermoplastic, Pro-Grid combines high-technology features and "service-ease" design for an unparalleled filtration value for both new pool and aftermarket installations.
High-rate sand filters use a special filter sand, normally .45 to .55 mm (also known as pool grade #20 silica sand), because it has sharp edges that separate particles, allowing filtration to take place. They operate on the basis of "depth" filtration where dirt is driven through the sand bed and trapped in the spaces between the sand particles. Initially, a clean sand bed removes larger particles, and then, as the bed starts to load up with debris, the filter removes finer particles. The sand can be cleaned by backwashing which involves reversing water flow through the filter to the "waste" line. Sand Filters trap debris as small as 20 to 40 microns

The crystal clarity of D.E. with cartridge convenience
Quad D.E.® Filters provide the highest water clarity of D.E. with the convenience and easy-cleaning features of a cartridge filter. Four easily accessible and removable D.E. cartridges greatly increases the filter's cleaning capacity. And, cleaning couldn't be easier. In fact, you have three options: backwash and recharge like a traditional D.E. filter, remove and rinse off the cartridges, or simply remove the lid, leave the cartridges in place, open the drain plug, and rinse.
An Eco Select™ Choice: Water flows very efficiently through Quad D.E.® Filters allowing the use of smaller pumps or lower pump speeds to minimize energy use. And when consumers rinse cartridges rather than backwash, they can significantly reduce water use, too.
The SuperFlo® Pumps are a product of nearly 50 years of innovative hydraulic engineering. The result is an ability to move more water more efficiently for lower operating cost and super-quiet operation. Plus, by performing with less effort, there's simply less wear and tear – and that means longer life for a higher return on your pump investment.
