FNS Plus Filters are designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. The internal design has been refined to minimize flow restrictions and, therefore, requires minimal pumping power to achieve a needed flow rate. This vertical-grid, D.E. filter is made of fiberglass-reinforced polypropylene for superior strength and reliability.
*Integrated Continuous High Flow Internal Air Relief is operational only when there is unobstructed flow in the circulating system.
Note: Operating limits—Maximum continual operating pressure of 50 psi. Pool/spa (bather) applications, maximum operating water temperature (internal filter) 104° F (40° C).
