Io Hvac Controls bal-12-extd 12 in Round Balancing Damper

Product Description

The IO HVAC CONTROLS bal-12-extd is a 12-inch extended round electronic remote balancing damper with an integrated actuator, designed for use in forced-air HVAC distribution systems. This damper provides motorized zone control within round ductwork, allowing airflow to be adjusted or shut off remotely without manual intervention at the damper itself. The extended body design accommodates installation in tighter or deeper duct configurations where a standard-depth damper would not fit. Licensed HVAC technicians typically install this component during zoning system commissioning or duct balancing work.

This damper is suited for residential and light commercial forced-air systems where precise zone control or airflow balancing is required. It fits into 12-inch round duct runs and is actuated electronically, making it compatible with zone control panels and building automation applications that call for remote-operated damper positions. Typical installation scenarios include multi-zone residential systems, HVAC retrofit zoning projects, and new construction where independent room or zone control is specified.

Key Features

• 12-inch round duct size fits standard 12-inch diameter ductwork
• Extended body design allows installation in constrained or deep-mount duct locations
• Integrated actuator eliminates the need for a separate motor assembly
• Electronic remote operation enables zone control panel integration
• Balancing functionality supports airflow distribution tuning across multiple zones

Compatibility

Designed as an OEM-style replacement or new-installation component for 12-inch round duct electronic zoning systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes. Power down the air handler and zone control panel before wiring the actuator to avoid damage to control components. Ensure the duct opening is clean and correctly sized at 12 inches before inserting the damper body. Refer to the zone control panel manufacturer wiring instructions for proper signal and power connections to the actuator.
