Io Hvac Controls BAL-2412 Electronic Balancing Damper

Product Description

The IO HVAC CONTROLS BAL-2412 is a rectangular electronic balancing damper with an integrated actuator designed for precise airflow control in ducted HVAC systems. Measuring 24 x 12 inches in duct opening size, this unit combines the damper blade assembly and actuator into a single, factory-mounted package. It is installed by licensed HVAC technicians in commercial and residential forced-air distribution systems where zone balancing or variable airflow management is required. The unit ships ready to install, reducing field assembly time and minimizing alignment errors associated with separately sourced actuators.

The BAL-2412 is suited for rectangular duct runs in new construction and retrofit applications where airflow must be regulated across multiple zones or branches. It is commonly installed in supply trunk lines, branch takeoffs, and air handler distribution systems that require electronic control. The integrated actuator allows the damper position to be driven by a building automation system, zone controller, or standalone thermostat with damper output capability. This makes it a practical choice for HVAC contractors managing multi-zone residential systems or light commercial VAV-style layouts.

Key Features

• 24 x 12 inch rectangular form factor fits standard duct opening dimensions
• Integrated actuator eliminates the need for a separately sourced, field-mounted actuator
• Electronic control input compatible with zone controllers and building automation outputs
• Factory-assembled blade and actuator assembly for consistent performance and simplified installation
• Compact package dimensions support installation in tight plenum and duct chase spaces

Compatibility

Designed as an OEM-style replacement or new-installation electronic balancing damper for rectangular duct systems requiring a 24 x 12 inch opening with an integrated electronic actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with SMACNA duct construction standards and applicable mechanical codes. Disconnect and lock out all power to the air handler and control system before beginning installation. Verify that the control signal voltage and wiring configuration from the zone controller or BAS matches the actuator input requirements before energizing. Do not force the damper blade manually while the actuator is powered, as this can damage the actuator drive mechanism.
