Automated Pure Water, Inc.’s Sand Trap separates and settles out sand, shale and oxidized organics. This is accomplished by running water through an internal swirl chamber then into a diverting plate, which allows heavier particles to settle to the bottom of the tank for blow down. Features include 0.75-inch (19.05-mm) blow-down drain, one-inch (25.4-mm) inlets and outlets, and 24-gpm (90.85-L/m) flow rate. No moving parts, no backwashing or electricity required, no filter cartridges or screens to clean or replace.www.apwinc.com(772) 567-2488
