AC Infinity 8 in Duct Silencer is a sound-absorbing duct component for grow rooms, HVAC systems and other ventilation setups where fan noise is a concern. It fits 8-inch ducting and inline fans, including the AC Infinity Cloudline T8, and installs between the fan and the ducting with no complex modifications. The core is thick egg-crate-patterned neoprene foam that absorbs sound waves and vibrations, reducing fan and airflow noise by up to 50%. The body is galvanized steel with dual aluminum flanges for corrosion resistance and durability. The duct opening measures 8 inches, the overall dimensions are 26.92 x 10.94 in. (68.4 x 27.8 cm), and the flange length is 1.50 in. (3.8 cm). The unit weighs 6 lbs and is maintenance-free. It is compatible with any 8-inch inline fan or ducting, and a second unit can be added on the intake side for greater noise reduction.
