Io Hvac Controls BAL-2618 Balancing Damper 26x18

Product Description

The IO HVAC CONTROLS BAL-2618 is a rectangular electronic balancing damper with an integrated actuator designed for precise airflow control in forced-air HVAC systems. Measuring 26 x 18 inches in nominal duct size, this unit ships at 12.936 pounds and fits within an overall assembly footprint of 20.75 inches wide, 7 inches tall, and 32 inches deep. The built-in actuator eliminates the need for a separate motorized operator, making it a self-contained balancing solution for zoning and airflow distribution applications. Licensed HVAC technicians and mechanical contractors install this damper as part of new construction or retrofit duct systems where airflow balancing is required.

The BAL-2618 is suited for residential and light commercial forced-air duct systems where electronic zone control or airflow balancing is required. It fits rectangular duct runs requiring a 26 x 18 inch nominal opening and is appropriate for installation in supply or return trunk systems where controlled modulation of airflow is part of the mechanical design. This damper is well suited for multi-zone systems where individual branch balancing is managed electronically from a central controller or zone board.

Key Features

• Ships as a complete unit at 12.936 pounds for straightforward receiving and staging

Compatibility

Designed as an OEM-style replacement or new-installation balancing damper for rectangular forced-air duct systems requiring a 26 x 18 inch nominal opening with electronic actuator control.

Installation Notes

Installation should be performed by a licensed HVAC technician or mechanical contractor in accordance with local mechanical codes and SMACNA duct construction standards. Disconnect and lock out power to the air handler and all zone control wiring before beginning installation. The damper must be mounted with the actuator accessible for future service and wiring connections made according to the zone controller manufacturer's low-voltage wiring requirements. Verify airflow direction and blade orientation before securing the damper in the duct opening.
