Pentair 450 SqFt System:3 Mod Media Modular Media Filter

Pentair Sta-Rite® System:3® 450 Sq. Ft. Modular Media Filter (S8M150)

The Pentair Sta-Rite® System:3® 450 Square Foot Modular Media Filter (Model S8M150) is a premium, high-capacity filtration system engineered to deliver commercial-grade pool water clarity for large-scale residential inground pools, hot tubs, and heavy-use architectural water features. Utilizing an advanced dual-cartridge concentric module with a shallow-pleat design, this unit provides 450 square feet of effective filtration area that yields maximum debris-holding capacity and filters out microscopic impurities without clogging. The split-tank design is crafted from high-density, weather-resistant Dura-Glas™ glass-reinforced composite resin, ensuring long-term structural integrity and absolute resistance to chemical corrosion in harsh outdoor environments. Its balanced-flow tank hydraulics route water evenly through both sides of the filter module, resulting in uniform dirt loading and an exceptionally high design flow rate of up to 124 gallons per minute (GPM) at a maximum operating pressure of 50 PSI. By relying on highly optimized media coverage, the System:3 handles two to three times more debris than traditional filters, often operating an entire swim season without requiring service, and completely eliminates the need for backwashing to conserve water and chemicals. Routine servicing is simplified by a rugged Posi-Lok™ clamp system for fast, secure access to the internal modules, a top-mounted pressure gauge, and dual bottom drain outlets for comprehensive winterization. The dry weight of the Pentair System:3 450 Sq. Ft. Modular Media Filter is approximately 147 pounds, standing as an ultra-durable, hydraulically superior, and low-maintenance centerpiece for premium residential pool pads.
