5) Automobile grade plastic spraying technology to ensure that the equipment is stainless
6) Dust removal filter element, abandoning the traditional cellulose filter paper or polyester fiber non-woven fabric with larger aperture and lower filtration precision, chooses new nano-fiber surface filter material, which has fine and good air permeability. There is also a layer of PTFE film imported from Japan on the surface. The dust filtration accuracy can reach 0.3 micron, and it can effectively screen and block over 99.99% of welded fume dust through flue gas. Not only that, the new filter material is also easy to clean ash, and has twice as long service life as the traditional filter material
7) Independent research and development of pulse ash cleaning and suction hood, flame retardant suction arm.
