Model ABD-Z1 is the latest addition to Greenheck’s line of automatic balancing dampers (ABDs) that provide on-demand control to ventilation systems. It combines a shutoff damper with an electric actuator, ABD, and a plenum box into one assembly. The addition of a low-leakage, volume-control damper to an automatic balancing damper allows the ABD-Z1 to shut off unoccupied zones. By only ventilating targeted spaces, the central fan’s energy consumption is minimized. The ABD-Z1 is ideal for use in apartments and condos, bathroom ventilation, education buildings and dormitories, hospitals and clinics, hotels and motels, and nursing homes and assisted living facilities.
