Rectangular Barometric Relief Dampers
Rectangular barometric relief dampers have a single blade design with an adjustable weighed arm to regulate static pressure. Like a motorized rectangular damper, these barometric dampers are of open frame design and are made to install inside a section of rectangular duct. Vertical mounting is suggested.
Application: Residential and light commercial low pressure duct systems.
Rectangular dampers are custom made and not returnable due to size or configuration errors.
Please carefully review your confirming invoice to ensure correct product for your application.
