Description:
The Trane BAYBARM011A barometric relief damper is used in commercial HVAC economizer systems to automatically relieve excess building air pressure while preventing outside air infiltration during equipment off cycles. Commonly installed in Trane Precedent rooftop units and commercial HVAC systems requiring gravity-operated pressure relief for economizer ventilation. Maintenance teams, HVAC service technicians, and system integrators use this barometric relief damper for replacement, retrofit, ventilation upgrades, and restoration of commercial HVAC air management systems.
Applications:
The Trane BAYBARM011A barometric relief damper is designed to maintain proper building pressure by automatically opening when internal air pressure exceeds a preset level and closing by gravity when pressure decreases. It is commonly used in commercial office buildings, schools, retail facilities, healthcare buildings, and packaged rooftop HVAC systems equipped with economizers where controlled pressure relief and energy-efficient ventilation are essential.
