The Pentair 180006 FNS Plus 24 sq. ft. Fiberglass D.E. Pool Filter provides the highest level of filtration. The FNS Plus is capable of filtering out particulate as small as 5 microns. That's the same size as a human red blood cell. The 180006 FNS plus uses a set or grids coated in pool grade diatomaceous earth. The set of grids consists of 7 full grids 12" in length and 1 partial grid 12" in length. The FNS Plus tank is made with fiberglass-reinforced polypropylene that enhances durability and product life. It uses a hi-flow 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 steel tension control clamp rests securely around the tank, a brass barrel nut securely fastens each half tightly together. To remove the 180006 FNS Plus requires a minimum of 48" vertical clearance. Before removing the dome lid, it is suggested to backwash the filter to discharge the contaminated DE powder.

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.
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.
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!
