THS Horizontal Sand Filter

The THS Series Filter is an NSF-approved 50 psi rated tank with flow rates up to 535 gallons per minute. The filter shell is manufactured from a lasting composite laminate design that makes winding unnecessary. Paracote®, a water-based, environmentally-friendly coating, provides remarkable surface protection.
