Suction arm

The working principle of the suction arm is to use a set of self-balancing connecting rod mechanisms as a full support frame inside the tube, so that the suction arm can rotate 360 degrees and hover at any position. When the handle on the hood is pulled, the suction hood can be easily stretched to any position that its arm length can reach, and it can position itself in the air without external force to absorb smoke and dust.

The use of the suction arm can effectively capture welding smoke, exhaust gas, dust, oil mist, oil smoke and other waste gases, prevent these harmful substances from spreading into the working environment, and thus protect the health of workers. The suction arm can be suspended at any position in three-dimensional space and placed at the front end of the engineering system. Its connection joints and rotating connection base fix the suction hood to remove dust and smoke from the worker's breathing zone.
