Gelcoat Fiberglass Sand Filter with Easy-open Selector Valve
The GFT Series delivers industrial-grade aquatic filtration through a reinforced tank structure and a premium gelcoat finish. Built to resist harsh UV rays and chemical wear, this gelcoat sand filter ensures long-lasting, stable operation across demanding indoor and outdoor commercial facilities. Because facility managers require equipment that maximizes uptime, the system features a ring-lock selector valve for immediate access to the media bed. This streamlined design drastically reduces service times, making it the ideal easy maintenance pool filter for high-traffic environments. Engineered for continuous heavy-duty use, the unit's non-corrosive construction prevents structural degradation, while the intuitive valve assembly integrates seamlessly with the robust gelcoated sand filter body so technicians can perform rapid inspections without specialized tools.
A trusted water treatment asset for international aquatic integrators requiring pool sand filter solutions.
