Duct Muffler

 |
Duct Mufflers can make their indoor gardening fans
significantly quieter, and can reduce noise heard from room to room. The
Duct Muffler, available in 6", 8", and 10" sizes (for use with same-size
ductwork) reduces noise by up to 25 dBA; a reduction by 3 dBA cuts a
listener's perception of sound by half! These Duct Mufflers are easy
to install, connect to existing ductwork, don't restrict airflow, and
require no maintenance. Support brackets not included. (dBA: DeciBels
