The Pentair 180009 FNS Plus Fiberglass D.E. Pool Filter provides the highest level of filtration. The FNS Plus is capable of filtering out particulate as small as 5 micros. Thats the same size as a human red blood cell. The 180009 FNS plus uses a set or grids coated in pool grade diatomaceous earth. The set of grids consists of 7 full grids 30" in length and 1 partial grid 30" 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 barrell nut securly fastens each half tightly together. To remove the 180009 FNS Plus requires a minimum of 86" vertical clearance. Before removing the dome lid, it is suggested to backwash the filter to discharge the contaminated DE powder.

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!
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. 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, pollen, dust, and even some bacteria, making your swimming pool a healthier environment.
