AC Infinity 6 in Duct Silencer is a duct silencer for reducing fan and airflow noise in indoor gardens and HVAC setups. It installs between the fan and the ducting, and pairs with an AC Infinity CLOUDLINE fan to cut noise levels by up to 50%. The core uses neoprene foam with a convoluted egg-crate pattern to absorb sound waves and vibrations. The body is galvanized steel, and the flanges are stainless steel and reversible so they fit over a fan or ducting flange. The duct opening is 6 inches, the flange length is 1.50 in. (3.8 cm), and the total dimensions are 20.86 x 8.93 in. (53.0 x 22.7 cm). It is compatible with any 6-inch inline fan or ducting. For maximum noise reduction, install it directly on the output side of the inline fan, before the ducting run.
