Io Hvac Controls BAL-2622 Electronic Balancing Damper

Product Description

The IO HVAC CONTROLS BAL-2622 is a rectangular electronic balancing damper with an integrated actuator, designed for precise airflow control in ducted HVAC distribution systems. At 26 inches wide by 22 inches in nominal duct size, this damper uses an electronic actuator to modulate blade position and balance airflow across zones or branches. It suits commercial and residential applications where manual balancing is impractical or where system conditions require automated adjustment. Licensed HVAC technicians and sheet metal contractors are the primary installers.

This balancing damper fits rectangular duct branches in forced-air systems where airflow distribution must be tuned across multiple zones. It is appropriate for new construction and retrofit installations in air handling systems that require branch-level volume control. The integrated actuator eliminates the need for a separate actuator mount, reducing installation steps. Typical applications include multi-zone HVAC systems, VAV-adjacent balancing, and duct systems requiring TAB (testing, adjusting, and balancing) compliance.

Key Features

• Rectangular form factor sized for 26 x 22 inch nominal duct openings
• Integrated electronic actuator for powered blade modulation
• Eliminates separate actuator mounting hardware and linkage assembly
• Suitable for both new construction and retrofit duct installations
• Supports automated airflow balancing without manual damper adjustment

Compatibility

Designed as an OEM-style electronic balancing damper for rectangular ducted forced-air HVAC systems requiring automated volume control at the branch or zone level.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling unit and de-energize all associated control wiring before installing or servicing the damper. Verify that low-voltage control wiring to the actuator is run in accordance with NEC requirements and the system controls manufacturer wiring guidelines. Do not force the damper blades manually when the actuator is energized.
