Zonefirst AOBD-12X10 Damper

The Zonefirst AOBD-12X10 is a heavy-duty automatic opposed blade damper designed for precision airflow management within forced air zoning systems. Measuring 12 inches wide by 10 inches high, this unit features an opposed blade damper configuration, which is the preferred choice for veteran technicians seeking to minimize air turbulence and ensure a more linear pressure drop compared to parallel blade designs. Utilizing a 24Vac power open/power closed actuator mounted on the 10-inch side, this damper provides positive control in both directions, eliminating the common failure points associated with spring-return mechanisms. A critical feature for advanced system integration is the inclusion of built-in end switches (SPDT), allowing for real-time proof of closure or opening to interlock with the air handling unit or secondary equipment. This Zonefirst AOBD series component is engineered for longevity in high-static applications where a standard HVAC zone damper might fail. Please note that this specific unit is non-cancelable and non-returnable.

• Enhanced Air Distribution: Opposed blade geometry provides superior balancing and reduced noise levels compared to standard bypass dampers.
• Industrial-Grade Actuator: The 24V damper actuator ensures high-torque operation for reliable cycling under varying duct pressures.
• System Feedback: Integrated end switches simplify wiring for contractors needing to verify blade position before firing the burner or compressor.
• Rugged Construction: Built to withstand the rigors of commercial and residential HVAC trunk lines without blade racking or binding.

• What is the benefit of the power open/power closed motor? Unlike spring-return motors, this actuator only draws significant power during the cycle and maintains its position more securely, reducing "chatter" against high-velocity airflow.
• Can this damper be used with any 24V zone control panel? Yes, it is compatible with most 3-wire zone control systems that support 24Vac power open/power closed logic.
• Where is the actuator mounted? On this specific 12x10 model, the motor is factory-mounted on the 10-inch height dimension.
