FNS
Fiberglass D.E. Filter
Micro-filtration for macro-clarity
Filtering with diatomaceous earth (D.E.) gives you water that really sparkles. Thats because D.E. filters remove the tiniest of contaminantsparticles as small as 5 microns. (An average grain of sand is 1000 microns!) Even though these particles cant be seen individually, collectively they greatly affect water clarity. Heres why diatomaceous earth filters work so well. Water passes through a series of D.E. coated grids. Under a microscope, D.E. looks like a collection of tiny sponges. And just like a sponge, water can pass through, but microscopic impurities like dirt, algae, and some forms of bacteria cant. FNS
● Corrosion-resistant fiberglass tank for long life.
● Top-to-bottom backwashing for optimum cleaning efficiency and sustained filter performance.
● Stainless steel tank clamp for secure closure of tank halves.
D.E. filters have been designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. Our exclusive internal design has been refined to minimize ow restrictions, and therefore requires minimal pumping power to achieve a needed ow rate. That means lower utility costs.
In addition to providing the clearest water possible, FNS was also designed for easy maintenance and long-term reliability. So you can count on it to keep your pool water clean and crystal clear for years to come.
How a D.E. Filter Works
When diatomaceous earth (D.E.) is introduced into the filter system, it coats the filter cloth. As water passes over the filter grids, the D.E. particles capture even the smallest suspended dirt particles. When cleaning is needed, the water ow is simply reversed.
