The ABD-Z2 is an integrated automatic balancing damper with an adjustable set point controlled by an electric actuator (24V or 120V). The unit can toggle between two pressure independent CFM setpoints. The low-flow setpoint maintains a constant minimum ventilation rate, while the high-flow setpoint provides boosted on-demand ventilation.
Helps achieve the requirements of ASHRAE 62.2 for indoor air quality. Ideal for apartments and condominiums, education buildings, dormitories, hospitals and clinics, hotels and motels, and nursing homes and assisted living facilities.
