Sta-Rite System 3 D.E. Filter S7D75

The Sta-Rite System 3 D.E. filter incorporates the world’s finest filtration technology, which produces the ultimate in water quality. Diatomaceous earth (D.E.), a natural substance, is so fine it traps dirt and debris as small as five microns (1/10 the width of a human hair). That means body oils, suntan lotions, pollens, dust and even some bacteria are trapped in the filter, leaving behind sparkling clear, healthier water. That’s why this filtration process is recommended by professionals for hotels, resorts and health clubs.

The System 3 D.E. filter removes dirt particles up to 10 times smaller than the particles removed by sand and cartridge filters. The internal multi-grid assembly captures virtually every kind of particle contaminant typically found in pool water. No other D.E. filter does a better job! Compared to some other D.E. filters, the System 3 is less complicated to service. If you’re the do-it-yourself type, you save time. If you leave the maintenance to a pool service, saving time means saving money!

Less maintenance . . .YES! The balanced-flow tank design directs water through both sides of each filter grid, which increases dirt loading without clogging. And that means a longer time between cleanings.

Easy, two-way cleaning - For quick and easy cleaning, simply move the valve selector to the backwash position - that’s it! In seconds, your System 3 is at work, keeping your water crystal clear.
