Zonefirst AOBD-10X8 Damper

The Zonefirst AOBD-10X8 Damper is a precision-engineered HVAC zone motor damper designed for professional contractors who require reliable ductwork airflow control. This automatic opposed blade damper features an extruded anodized aluminum frame and parallel-acting blades that minimize air turbulence while providing a tight seal for effective HVAC zoning. The AOBD-10X8 is equipped with a high-torque 24Vac motorized actuator that operates in a power-open/power-closed cycle, ensuring the blades stay in position without the constant draw of a spring-return system. With integrated end switches, this unit provides immediate feedback for zone control systems and auxiliary terminal equipment. This specific model measures 10 inches wide by 8 inches high and is designed for a side-mount installation on the 8-inch dimension, making it the ideal solution for residential HVAC zoning retrofits or new forced air systems where space and precision are paramount. Its thin profile allows for easy insertion into existing ductwork through a simple three-inch slot.

• Efficient Airflow Control: The opposed blade design reduces static pressure and provides balanced air distribution across the zoning system.
• Precise System Feedback: Integrated end switches allow the dual-position actuator to signal control panels or sequence additional HVAC equipment.
• Durable Construction: Built with extruded aluminum and stainless steel linkage to withstand high-velocity airflow and constant cycling.
• Low Maintenance Operation: The power-open/power-closed motor only draws 6W of power during its 30-second transition, extending the lifecycle of the motorized zone damper.
• Simple Side-Mount Installation: Designed to slide into a standard 3-inch slot on the side of the 10x8 duct, secured by self-tapping screws.

Is the AOBD-10X8 compatible with standard smart thermostats?
Yes, when used with a compatible HVAC zone control panel, this 24V damper can be integrated into any system utilizing modern smart thermostats.

Can this damper be installed in a vertical duct?
While optimized for side-mount in horizontal runs, this motorized damper can be installed in vertical applications provided the actuator is positioned to avoid moisture accumulation and allows for proper linkage clearance.

What happens during a power failure?
The AOBD-10X8 is a power-open/power-closed model, meaning the blades will remain in their last known position if power is lost, preventing the unwanted loss of air pressure in critical zones.
