Description

Keep your high-velocity fans quiet with duct mufflers. HTG Supply mufflers are built with the same acoustic foam used in recording studios, which absorb and muffle the noise created from fans. Grow rooms can benefit from this in multiple ways, it keeps your tent discreet and it is less loud to work inside. High-Intensity Discharge lighting needs to be kept cool with high-velocity fans which pair perfectly with duct mufflers.
