Backdraft dampers are made of galvanized steel and prevent air leakage into your fan setup. They are easy to install, fit directly onto the ducting, and prevent a back draft of air when the fans are switched off. They also save CO2 and prevent odors from flowing backwards. Silencers reduce noise from fans and carbon filter systems, are easy to hang with lightweight aluminum construction and, do not rust! The best location is as close as possible to the source of noise.
