The suction arm is ideal for absorbing welding fumes, gases, flying dust, aerosol solutions, etc. The internal joint suction arm consists of a quadrilateral multi-joint bracket supported by an internal spring, which should be coated with high temperature and corrosion resistant PVC coating on the inside and outside, and composed of fiberglass hose with a spiral steel wire skeleton. The suction hood is equipped with an air volume adjustment valve and can be rotated 360° to any position. The entire joint design is as flexible as a human arm, and the suction hood is like a palm. The operator can pull the handle of the suction hood to reach any position and direction that the length of the suction arm can reach, and position itself in the air without other support. The suction arm can be connected to a stand-alone smoke purifier or a central purification system pipeline.The external joint suction arm is ideal for work environments designed to absorb large amounts of smoke, vapor or non-explosive dust. Typical workplaces include metal manufacturing or other industrial environments that require high-volume air extraction. It can be used in welding, laser or manual plasma cutting, metal spraying, grinding processes, or other activities that require a lot of spatter. The suction arm has excellent balance performance and is easy to position. Depending on the actual working conditions, 2M-4M suction arms can be configured.
