The P750-1400 Series represents the heavy-duty range of the industry-standard P Series pool filtration line, utilizing the same proven bobbin-wound fiberglass reinforced tank construction trusted for decades. These larger-capacity filters are specifically designed for commercial pools, water parks, aquatic centers, and large residential installations requiring higher flow rates and greater filtration capacity. The UV-resistant surface finish protects against prolonged sunlight exposure, ensuring years of reliable outdoor operation. This comprehensive series includes six models (P750, P800, P900, P1000, P1200, and P1400), offering filter areas ranging from 0.45m² to 1.54m² and maximum flow rates from 23m³/h to 56m³/h. Each filter is equipped with a seven-position multi-port valve featuring upgraded 2-inch (63mm) connections to accommodate higher flow requirements. The ABS lateral assembly ensures optimal water distribution throughout the larger filter bed, maximizing filtration efficiency. The robust construction handles operating pressures up to 36 psi (2.5 bar) and temperatures up to 43°C (109°F). All models are designed to work optimally with 1-2mm filter media. Ideal for commercial swimming pools, aquatic centers, hotel and resort complexes, water parks, large residential pools, community pools, and high-traffic public pool facilities requiring superior filtration performance and reliability.
