The Zonefirst AOBD-10X10 is a heavy-duty automatic opposed blade damper designed for precision airflow management in commercial and residential zoning applications. This 10-inch by 10-inch unit utilizes an extruded aluminum frame and blades to ensure structural integrity and corrosion resistance within the plenum. The integration of a 24Vac actuator provides high-torque, power open power closed logic, ensuring the damper reaches a positive seal without the reliability issues associated with spring-return components. For technicians requiring sequence-of-operation feedback, the built-in SPDT end switches allow for easy interlocking with auxiliary equipment or controller verification. The zoning system performance is enhanced by the opposed blade geometry, which reduces turbulence and provides a more linear flow characteristic than standard parallel blades. Engineered for longevity, the HVAC damper assembly features low-friction bearings to maintain smooth operation under high static pressures, making it a reliable choice for field-heavy retrofits and new installations.

Key Benefits

• Opposed blade design ensures minimal air turbulence and more accurate flow control compared to single-blade alternatives.
• Integrated SPDT end switches provide dry contact signals to verify damper position for system logic.
• All-aluminum construction with nylon bearings prevents rust and ensures quiet operation in high-velocity ductwork.
• The MA-POPC motor provides consistent 24V operation, eliminating the common mechanical fatigue found in spring-type actuators.
• Universal 3-wire wiring configuration allows for seamless integration with most industry-standard zoning panels.

Common Questions

Can the AOBD-10X10 be installed in any orientation?
Yes, this professional-grade damper is engineered to function reliably in both vertical and horizontal duct configurations without affecting the torque of the actuator.

Is this damper compatible with standard 24V thermostats?
This unit is designed to work with a 3-wire zoning panel or a SPDT switch. Direct connection to a standard 4-wire thermostat may require an interface relay depending on the control circuit.

How do I utilize the built-in end switches?
The end switches provide a signal when the damper reaches its fully open or fully closed position, which a technician can use to trigger a blower motor or a status light on a custom control board.
