Dampers and Accessories

Whether for new construction or retrofitting, Grainger has the HVAC dampers and accessories you need for your HVAC system. From backdraft, isolation, and balancing dampers we have the components to regulate the airflow in HVAC applications. Backdraft dampers allow airflow in one direction and help prevent reverse airflow. Roof dampers are suitable for your roof exhaust needs and are available in a variety of sizes and mounting styles. We also have a selection of motorized dampers including volume control channel-style models that can regulate airflow in medium- and low-pressure commercial applications. Motorized fire dampers and smoke dampers are designed to help protect your building by automatically closing to prevent fire and smoke from passing through the ductwork.
