iO HVAC Controls BAL Series Electronic Balancing Damper — Remote-Powered Motorized Airflow Balancing (Round)

Description

The iO HVAC Controls BAL Series Electronic Balancing Damper delivers precise, remote-controlled airflow balancing for residential and commercial HVAC systems. Designed for hard-to-reach or finished ceiling installations, these dampers eliminate the need for field power and allow technicians or installers to fine-tune airflow from a convenient handheld controller.

Each damper includes a factory-mounted 9VDC gear-driven actuator with dual RJ11 ports, enabling fast setup and reliable performance. Up to nine dampers can be linked together in a daisy-chain configuration, offering a flexible, scalable balancing solution. The system ensures direct proportional control, allowing the damper to open or close to an exact position via the handheld BAL-C controller (BAL-C Sold Separately). Perfect for inaccessible areas, retrofits, and any application requiring precise remote adjustment.
