Io Hvac Controls HD-16 Round Heavy-duty Damper 16 in

Product Description

The IO HVAC CONTROLS HD-16 is a 16-inch round heavy-duty damper designed to regulate airflow in ductwork systems. It provides positive shut-off and flow control in supply, return, or exhaust air applications. Built for durability under repeated cycling, this damper suits commercial and residential HVAC installations where a robust, reliable blade assembly is required. Licensed HVAC technicians and sheet metal contractors are the primary installers. At 9.35 pounds, the HD-16 carries the mass expected of a heavy-duty unit intended for long service life in demanding duct systems.

The HD-16 is suited for round duct installations in forced-air heating and cooling systems. Its 16-inch diameter fits standard round duct collars commonly found in commercial rooftop unit distribution systems, large residential systems, and industrial ventilation layouts. It is appropriate for use as a zone control damper, balancing damper, or isolation damper depending on system design. HVAC technicians will typically pair this damper with a compatible actuator for automated zone control applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards. Disconnect and lock out power to the air handling unit and any associated controls before beginning installation. Ensure the duct collar is clean, round, and free of deformation before inserting and securing the damper. If an actuator is being mounted, follow the actuator manufacturer's torque and linkage specifications separately.
