Barometric Bypass Damper

The Round Take-Off ByPass Damper (RTB) from Zonefirst® is a new, barometric bypass damper with a single blade. It is a counter balanced, weighted damper that operates on air pressure in order to control the flow of bypass air. The RTB has an adjustable arm and weight to maintain the correct amount of pressure in the duct system. It can be mounted in both horizontal and vertical positions for either upflow or downflow systems. The RTB is available in 8, 10, 12, 14, or 16 inches and should be ordered as model RTBdd.
