Mini side channel blower,made in Korea.

High speed mini-side channel blower is a series of segments that are grouped into three sections, 
blower body which contains an impeller, motor, and silencer. The silencer reduces noise sound 
levels when running and is detachable from the body. The blower can be used as a complete unit 
with the silencer removed. Applied impeller to the blower is side channel type which was designed 
through CFD (Computational Fluid Dynamics) for its performance and efficiency optimizations.
