Io Hvac Controls HD-10 Round Heavy-duty Damper 10 in

Product Description

The IO HVAC CONTROLS HD-10 is a 10-inch round heavy-duty damper designed to control airflow in ducted HVAC systems. It mounts inline within round ductwork and provides reliable zone control or shutoff capability for both residential and light commercial applications. The HD-10 is built for durability in demanding installation environments where a standard-duty damper would be insufficient. HVAC technicians and sheet metal contractors install this damper during new construction or as a direct replacement in existing duct systems requiring upgraded airflow control hardware.

The HD-10 is suited for round duct installations in forced-air heating and cooling systems. It is commonly installed in zone control setups, ventilation branches, or main trunk lines where positive airflow regulation is required. Its 10-inch diameter fits standard round duct sizes used across a wide range of residential and light commercial forced-air system configurations. Installation typically takes place in accessible duct runs, mechanical rooms, or attic and crawlspace ductwork.

Key Features

• 10-inch round duct diameter for compatibility with standard round ductwork
• Heavy-duty construction rated for demanding HVAC airflow control applications
• Overall dimensions of 12.75 x 13 x 12.75 inches to confirm rough-in clearance before installation
• 5.3-pound weight indicating robust build quality suitable for permanent installation

Compatibility

Designed as an OEM-style replacement or new-installation damper for 10-inch round duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Always power down the air handler and any associated zone control board before connecting or wiring the damper actuator. Secure the damper to duct sections using sheet metal screws and seal all joints with listed duct sealant or foil tape per applicable mechanical codes. Verify that the 12.75 x 13 x 12.75-inch overall footprint clears surrounding framing, insulation, and adjacent duct components before final mounting.
