A high performance, totally corrosion-proof filter series that combine superior filtration and features with ease of operation. Designed with the pool owner in mind, the S210T S210S S244T and S244S filter series is the ultimate in high-rate sand filtration.

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.

Applications

• In-ground pools of all types and sizes
