Zonefirst AOBD-12X6 Damper

The Zonefirst AOBD-12X6 is a professional-grade Automatic Opposed Blade Damper engineered for high-performance HVAC zone control. Developed for precision airflow management, this 12" wide by 6" high unit features an opposed blade configuration, which is superior for reducing air turbulence and providing more linear flow characteristics than parallel designs. It comes factory-equipped with a heavy-duty 24Vac Power Open/Power Closed Actuator mounted on the 6" side, ensuring the blades maintain their position without drifting under high static pressure. The inclusion of built-in end switches is a critical feature for technicians, allowing for effortless integration of status feedback or equipment interlocking. This motorized damper is constructed with extruded aluminum for long-term durability and smooth operation in demanding commercial or residential duct systems. Designed for direct 24V wiring, it interfaces seamlessly with most standard zoning panels. Note that this specific model is Non-Cancelable / Non-Returnable, so confirm your field dimensions and sequence of operation before purchasing.

Key Benefits for Contractors

• Built-in end switches provide dry contact closure to signal equipment when the damper is fully open or closed.
• Opposed blade design ensures more balanced air distribution and less noise in the duct register.
• Heavy-duty 24Vac motorized damper motor provides active control in both directions for reliable seal and bypass management.
• Extruded aluminum frame and blades offer high corrosion resistance and structural integrity.

Common Technical Questions

Does this damper require a 3-wire or 2-wire connection?
This model utilizes a power open and power closed actuator, which typically requires a 3-wire setup from the zone board or thermostat to manage the active drive in both directions.

Can the actuator be replaced if the motor fails?
Yes, the actuator is design-mounted on a standard shaft, allowing for field replacement without removing the entire damper frame from the ductwork.

What is the purpose of the end switches in this application?
The end switches allow you to interlock the damper with an air handler or boiler, ensuring the equipment doesn't fire until the damper is confirmed in the correct position.
