Duct Work

Ducting - You can safely and easily vent your ballasts and reflectors with this flexible two-ply, Metallic Vent Fan Tubing. This heavy-duty ducting is UL-listed and fire-resistant.

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.
