Duct Mufflers

Make indoor gardening fans significantly quieter, reducing noise by up to 25 dBA—a reduction by 3 dBA cuts a listener's perception of sound by half! Duct mufflers are a cinch to install, connect to existing ductwork, don't restrict airflow and require no maintenance. Support brackets not included.		 Duct Mufflers
