ABD-Z2 : Automatic Balancing Damper for Zone Register Terminals

ABD-Z2 : Automatic Balancing Damper for Zone Register Terminals

Model ABD-Z2 features an integrated automatic balancing damper (ABD) capable of toggling between two pressure-independent CFM setpoints via an electric actuator. The low-flow setting maintains a constant minimum ventilation rate for baseline compliance, while the high-flow setting delivers boosted, on-demand ventilation as occupancy or system demands increase. By providing dual setpoint control within a single assembly, the ABD-Z2 supports energy-efficient operation, improved indoor air quality, and simplified zone ventilation management.
