Made of galvanized steel, the single blade automatic round HV damper features a power close, spring open construction to ensure minimal leakage while controlling circulating air in zoned heating, cooling and ventilation systems. Creating multiple temperature zones in the home can help your customers save money and energy. Zoning makes heating or cooling a home more efficient by delivering airflow to zones where it wanted and blocking airflow to the areas it not. The 12 in round automatic damper regulates airflow for proper zoned heating and cooling.
