Essential Info

HVAC systems with 3 or more zones should be equipped with a pressure relief bypass duct to prevent over pressure buildup that may damage the system. This duct is installed just ahead of the blower. It opens and redirects some of the airflow back into the blower intake when pressure builds up due to many dampers being closed. This mechanical bypass duct, constructed of Galvanized Sheet Metal, is continuously variable, and the pressure relief level is easily adjustable.

    Recirculates excess supply pressure through the cold air return system. Relieving over pressure and preheating the air for the zone calling for heat. The results are faster heating in the zone calling for heat, and reduced pressure build up. Makes your multi zone system more efficient.
