We carry a selection of backdraft dampers, ducts and duct adaptors. Our Backdraft dampers from Fantech are spring loaded and come in sizes from 4 inches to 12 inches. Backdraft dampers prevent the backdraft flow of air when the exhaust fans are off. We also have insulated ducts, duct adaptors and duct connectors in various sizes.
