Pentair 100 SqFt Dynamic Series II Top Load High Flow Filter

The Pentair Dynamic® Series II RTL100 100 Square Foot Top-Load High-Flow Cartridge Filter (Product #: R172505) is a high-performance, space-saving fluid-sanitation vessel engineered specifically for large custom hydrotherapy spas, commercial hot tubs, and small residential swimming pools. Designed for clean, vertical integration into tight equipment configurations, this inline filtration system features 2-inch slip solvent weld connections that install directly onto standard PVC plumbing, eliminating hydraulic restriction to support a powerful maximum design flow rate of up to 100 gallons per minute (GPM). Inside, the system houses a single, premium coreless polyester cartridge element that utilizes advanced pleated fabric science to provide 100 square feet of effective filtration area, systematically trapping micro-particulates, suspended algae, and organic contaminants down to 20 microns for pristine water clarity. The rugged filter housing is molded from high-impact, UV-stable and heat-resistant polymer resins, giving the unibody shell absolute immunity to chemical corrosion and structural fatigue under elevated spa water temperatures and continuous working pressures. Routine filter maintenance is highly simplified by the convenient top-load design; pool owners can easily spin off the heavy-duty lock ring and extract the cartridge module vertically for a quick rinse without needing specialized tools or draining the entire plumbing line. The dry product weight of the Pentair Dynamic Series II RTL100 100 Sq. Ft. Cartridge Filter is approximately 8 pounds (standing 31.5 inches tall with a slim, space-efficient tank diameter of 8.25 inches), providing spa builders and homeowners with an exceptionally lightweight, durable, and hydraulically optimized sanitation centerpiece.
