Io Hvac Controls BAL-2212 Electronic Balancing Damper 22x12

Product Description

The IO HVAC CONTROLS BAL-2212 is a rectangular electronic balancing damper with an integrated actuator, designed for precise airflow control in ducted HVAC systems. Sized for a 22 x 12 inch duct opening, this unit combines the damper blade assembly and actuator into a single factory-mounted package, reducing field assembly time. It is used to balance airflow distribution across zones or branch runs in residential and light commercial forced-air systems. Licensed HVAC technicians typically specify and install this component during system commissioning or retrofit balancing work.

This damper is suited for rectangular duct applications where electronic modulation or on/off airflow control is required. It fits into new-construction duct systems as well as retrofit installations where manual balancing dampers are being upgraded to electronically controlled units. Typical install scenarios include multi-zone forced-air systems, VAV-style residential zoning, and energy-recovery ventilation balancing applications. The integrated actuator eliminates the need to source and mount a separate actuator in the field.

Key Features

• Integrated actuator and damper in a single assembly for simplified installation
• Designed for 22 x 12 inch rectangular duct openings
• Electronic control enables precise zone balancing and modulation
• Compact packaged dimensions: 13 inches wide, 7 inches tall, 28 inches deep
• Factory-mounted actuator reduces field labor and alignment steps

Compatibility

Designed as an OEM-style electronic balancing damper for rectangular ducted forced-air HVAC systems requiring a 22 x 12 inch damper assembly with an integrated actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage control wiring and duct fabrication practices. Shut down the air handler and de-energize all control circuits before installing or wiring the damper. Verify duct opening dimensions and airflow direction prior to securing the damper in place. Follow all applicable mechanical and electrical codes, including local adoptions of the IMC and NEC, for duct penetrations and low-voltage wiring.
