Resideo ZD28X6TZ 2-Position Parallel Blade Damper S/R 228"L X 6"H 24V

The Resideo ZD28X6TZ Parallel Blade Damper is an air control component designed for highly efficient HVAC systems. This rectangular damper is powered by 24V and has parallel blades that allow for the control of airflow. Its actuator is a Spring Return (S/R) which means that the blades will be returned to their default position in the event of a power failure. In HVAC systems it is used to control the airflow in large duct works hence useful in applications that require precise control of the airflow and temperature.
