Pentair may have redefined the industry with its smart solutions for pool and spas with dependable performance and easy maintenance, but its FNS PLUS DE FILTERS are still a major breakthrough of the brand for leveling up the filtration systems that other brands offer.

What people can expect from the PENTAIR FNS PLUS DE FILTER' technology include: more surface area for better pool filtration and less maintenance; curved grids design to maximize filtration area, as more filter area means better performance and longer periods between cleanings; and inclusion of an internal design that has been refined to minimize flow restrictions and, therefore, requires minimal pumping power to achieve a needed flow rate.

Regardless of the promises offered by Pentair, standard wear and tear issues may soon render these filters unusable. You can prevent that by considering the repair parts you can find in this category as the genuine replacements you will need to get them right back up running again.

The first component in this category you may soon need replacing is the: V38-140 VAL-PAK HEAVY DUTY TOP MANIFOLD AMERICAN, FNS PLUS. With this component, your filter's fiberglass-reinforced polypropylene will be able to offer superior strength and reliability.

The next item you may need to replace is the 190141 Pentair FNS Plus Filters Bulkhead (2 in. with Oring 2). The promise of the filter to offer the Service-Ease™ Grid Pack feature with Integrated Continuous High Flow™ Internal Air Relief is dependent on this bulkhead.

The 192165 PENTAIR BREATHER TUBE FNS Breather Tube is available in this category, too. We placed this here because this is a key component for your the FNS Plus to maximize its High Flow Manual Air Relief Valve feature that offers Top-to-bottom backwash.
