Gel-Coated Fiberglass Filter with Easy-open Transparent Lock Lid
The GFS Series provides highly durable filtration solutions engineered for both residential and commercial applications. Built with a non-corrosive gelcoat tank, this fiberglass filter for pool installations offers superior surface quality and robust structural integrity. It is designed to deliver long-term performance stability, making it an optimal choice for demanding outdoor environments where chemical and environmental degradation must be minimized. This product series is available in multiple configurations supporting 1.5-inch and 2-inch valve connections to accommodate different plumbing requirements. The unit functions as an efficient and easy maintenance pool filter, featuring an integrated air release valve. With its smooth finish and refined aesthetic, the system provides enhanced UV resistance and superior protection against harsh operating conditions compared to standard bobbin-wound alternatives. Operational accessibility is maximized through a specialized hardware design that eliminates the need for complex mechanical interventions. Operators can inspect the internal media via a clear visibility cover, establishing the unit as a practical tool free sand filter for facility managers. Furthermore, the tank can be produced in varying colors to match specific architectural preferences without compromising on the standard operating pressure rating of 2.5 bar.
