Air line hood silencer and protective hood equipped with the air line hood silencer

摘要

Disclosed herein are a silencer for an airline hood and a protective hood having the silencer. The present invention reduces the speed of air fed into a space between upper and lower units, using an air distributing means, prior to discharging the air through air outlet holes formed on the lower unit to the outside of the space, thus minimizing noise due to the air. Further, the silencer for an airline hood is installed in the protective hood, thus minimizing noise, therefore increasing work efficiency, when a worker works with the protective hood on.
