Barometric!By,Pass!Dampers! The Static Pressure Regulating Dampers are barometric relief. dampers used to by-pass excess air pressure on zoned systems. The. dampers automatically respond to the air pressure in duct as the. various zone dampers open and close. As zone dampers close off air to a number of zones, the supply air. pressure in the duct system will increase. This increase in air pressure. can increase the noise level and reduce the flow of conditioned air. through the HVAC Unit. Using a by-pass damper solves this by.
