1.Multi-joints flexible arms.Horizontal part with rotating joint structure, which make the horizontal flexibility and increase the effective active angle.
2.The built-in support and link structure is made of aluminum alloy materials, of light weight, which make the arm more flexibly, all the links between joints designed in a fluid way and the corner is treated in a smooth transition in order to reduce the wind resistance.
3.Link flexible suction arm intermediate by friction plate made of composite materials of 80mm, increase the friction in the contact area and prolong the service life of the friction plate.
4. This arm frame/support structure adopts the aluminum alloy material, of no rust,Corrosion resistant, acid and alkali salt, high temperature resistance, light weight, high intensity, labor-saving operation with power device, hovering freely,
5. can be connected to welding smoke purifier equipment and dusting collection equipment, can be directly mounted on the wall or the duct system
6. optional accessories: a cover opening fire net; working lamp; light, smoke,temperature sensing probe
