The FNS plus uses a set or grids coated in pool grade diatomaceous earth. The set of grids consists of 7 full grids 18" in length and 1 partial grid 18" 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 through 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 62" vertical clearance. Before removing the dome lid, it is suggested to backwash the filter to discharge the contaminated DE powder.
