Vertical Barometric Bypass Dampers

Description

This product has been discontinued by the manufacturer

BV series barometric bypass dampers are used to automatically bypass excess air when increases in duct static pressure occur due to closing of zone dampers. Various relief air control settings are accomplished by simple adjustment of the weight on the arm. Barometric relief dampers are recommended for systems up to 0.75″ W.C. of static pressure. (For higher pressure systems use EB motorized bypass dampers.)
