Pentair 28.5"W x 42"H Mod Media™ Top Mount Filter Black

The Pentair Sta-Rite® System:3® Mod Media™ S7M120 300 Square Foot Modular Media Filter (measuring exactly 28.5 inches wide by 42 inches high with an attractive, contemporary matte black finish) is a high-performance, ultra-capacity pool filtration vessel designed to deliver flawless water clarity for mid-to-large residential inground swimming pools, high-volume spas, and intricate backyard water features. Rather than utilizing a traditional, multi-cartridge nest, this advanced system features Sta-Rite's signature dual-concentric modular media core, incorporating perfectly balanced fluid-distribution manifolds that push water evenly through both sides of the filter modules. This specialized hydraulic layout ensures uniform debris loading and prevents premature clogging, giving the system two to three times the dirt-holding capacity of conventional filters and enabling trouble-free, season-long performance without requiring a single washdown. The stout, circular tank housing is injection-molded from Dura-Glas™, a proprietary high-density fiberglass-reinforced composite resin that provides permanent immunity to pool chemicals, rust, and harsh outdoor weathering under a maximum continuous operating pressure of 50 PSI. Hydraulically optimized for energy-efficient setups, the filter features 2-inch quick-connect plumbing ports that easily manage a steady continuous design flow rate of 100 gallons per minute (GPM), pairing flawlessly with variable speed pumps to lower monthly utility bills. Routine servicing is highly simplified by a heavy-duty Posi-Lok™ split-tank clamp system that provides fast, tool-free access to the internal chamber, a top-mounted dual-view pressure gauge, an internal high-flow air relief, and a dual-drain plug layout featuring a side waste port and a bottom tank drain for rapid winterization. The dry product weight of the Pentair System:3 S7M120 300 Sq. Ft. Mod Media Filter is approximately 135 pounds (with a boxed shipping weight of roughly 145 to 150 pounds), providing pool professionals and discerning estate owners with a hydraulically superior, incredibly robust, and low-maintenance centerpiece for modern aquatic equipment pads.
