The Pentair 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 microns. That's the same size as a human red blood cell.

The 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 barrel nut securely fastens each half tightly together. To remove the 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.

Common Questions:

What are the dimensions of the tank?
  • Tank Dimensions: (DxH) 21.5" x 55"
  • Weight: 84 lbs.
How much DE do I add?
  • The FNS Plus uses 6 lbs of DE.
What is the max GPM flow rate?
  • The max GPM flow rate is 150 GPM.
What does FNS Plus come with?
  • The FNS Plus comes with the tank, steel clamp, air relief valve, and threaded bulk heads.
Does the FNS Plus come with a backwash valve?
  • No. The FNS Plus does not come with a backwash valve. For a multi-port valve option, we suggest item number 261152 for 2" plumbing and 261177 for 1.5" installations. For a side-mount push-pull valve, we suggest item number 263064.
What is the warranty for the FNS Plus?
  • One year parts only warranty from the date of purchase. Please see the Pentair Warranty Card for more details.

Energy Efficient
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!
Low Maintenance
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.
Diatomaceous Earth (D.E.)
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.
