The arm hood is a local discharge device that safely protects the user and the handling region from contaminated materials by promptly discharging a small quantity of contaminated air in a specific location.
- The air discharge system consists of the joint structure with free spinning and upward and downward movement so that movement toward a specific location is free.
- The damper that can control the air discharge speed is attached so that the user can arbitrarily control the air speed depending on the working circumstance.
