Product details

The Pentair FNS Plus FNSP36 is a 36 square foot vertical grid DE filter for inground pools, Pentair part number EC-180007. DE filtration gives the finest water polish of the three filter types, and the FNS Plus design is built around getting the most filter area out of a compact tank.

Curved grids, more capacity

The grids inside are curved rather than flat, which fits more filtration surface into the same diameter. More surface holds more dirt, so the filter runs longer between backwashes and cleanings. The internal flow path is refined to minimise restriction, so the pump needs less power to push the required flow, and that shows up as lower running costs.

Built to last on the pad

The tank is chemical resistant polypropylene reinforced with fiberglass for strength. The grid pack is removable as one assembly, so when it is time for a full clean you lift it out, hose it down and drop it back in rather than fighting with individual grids.

Before you order

This is the 36 sq. ft. size in the FNS Plus range. Match filter area to your pump flow and pool volume; if you are replacing an existing FNSP36, this is the direct like for like unit.

Questions and answers

What people ask about this product, answered by our pool techs.

What does 36 sq. ft. mean?
It is the total surface area of the DE grids inside the tank. More area means more dirt holding capacity and longer runs between cleanings for a given pool.
Why curved grids instead of flat ones?
Curving the vertical grids packs more filter surface into the same tank diameter. That is what gives the FNS Plus its capacity without a larger footprint.
How is it cleaned?
Backwash to flush the DE and dirt, then recharge with fresh DE. For a deep clean, the grid pack comes out as a single removable assembly so you can hose the grids off.
Is the tank plastic?
It is fiberglass reinforced polypropylene, chosen for chemical resistance and strength rather than a plain molded plastic.
