First, the system benefits 
 1, flexible suction arm to balance the design, any stretching, rotation can be freely positioned. 
 2, multi-level design universal joint, the welding operation, may change with welding position hood can be adjusted at the position and angle to get the best collection of dust effects. 
 3, suction hood with air flow control valve and the human hand, to prevent foreign matter is inhaled, the entrance hood with protective net. 
 4, the hood can be rotated 360 degrees of freedom, at any time to adjust to absorb smoke the best results. 
 5, the suction arm for the metal used in wire-type hose inside and outside the PVC coated glass fiber hose, tube diameter? 160mm high temperature and corrosion resistance. 
 Second, the scope of application: 
 1, due to large-scale production requirements, the workshop produced by the multi-station welding fumes, etc., I developed the company's central smoke purification system to meet a number of different stations while welding fumes generated by cleaning of the collection needs. 
 2, the central charge of road dust cleaning system, through an extension to the side, the pipe may need to use T-, I-type, adjustable tube, 90 
 Degree elbow connection, and a safety fixtures, installed at each station over a desired length of the suction arm (or suction 
 Cover) This is an absorption, filtration, purification of the complete set of the central dust extraction systems.
