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's wanted and blocking airflow to the areas it's not. The 12-inch Round Automatic Damper regulates airflow for proper zoned heating and cooling.
