Suncourt Duct Muffler 10″
The Suncourt Duct Muffler (also sometimes known as a Duct Silencer) is a passive device that is installed in ductwork to help reduce the level of noise that is transmitted through the duct.
The Suncourt Duct Muffler is a completely passive device that will not impede airflow when it is attached to the ductwork. It is made of metal and is lined with an acoustic insulation that reduces sound. The insulation is covered with a wire mesh to keep the insulation in place.
