Description
The IO HVAC Controls BH-10 Round Horizontal Barometric Bypass Damper regulates excess air pressure by automatically opening to redirect airflow when system static pressure rises above the set level. It operates through a weighted barometric mechanism that responds to pressure changes without requiring electrical control, it maintains balanced airflow in HVAC systems such as zoned heating and cooling equipment. Designed with a 10″ round horizontal configuration, it is connected within the duct system to bypass excess air between supply and return sections. Its operation supports stable air circulation, it reduces duct pressure buildup, and it contributes to efficient system performance.
