Field Controls GVD-7PL 7" Automatic Vent Damper 24V UPC Code: 09074757810

The Field Controls GVD-7PL 7" Automatic Vent Damper makes 24V gas heating systems more energy efficient by controlling airflow. When the burner is not running it prevents heat from escaping. The damper opens on its own during burner use and then shuts when the system is not running. With a 24V motor, the damper blade moves according to system signals to deliver better ventilation control. It is a popular choice for HVAC gas furnaces and boilers because it works well with existing installations. Advantages are better system efficiency, less energy use and bills savings, all while keeping the home comfortable.
