casters with brake device for easy moving and stationing. It is suitable for the purification of fume and dust
generated in all kinds of welding, grinding and other places as well as for collecting rare metal particles and
2. Suction arm can be rotated 360 °, and can flexibly and easily reach the position and angle of sucking by pulling
the handle of the hood and position by itself in the absence of external force. Depending on needs, 2m, 3m or
4m flexible suction arm are available. Suction hose uses high temperature-resistant, flame retardant and wear-
resistant composite materials, and will not crack after burning through by spark and has a longe usage life; the
arm diameter is 160mm.
3. Fume generated in working will be sucked into the purifier through the hood, first through the fire resistance net,
large particles and sparks produced in grinding is intercepted and separated; then enter fume directing layer,
i.e. deflector, to ramify the fume to avoid residual spark into the main filter cartridge directly; at last the fume
enter the third layer i.e. the main filter cartridge, for ultimate purification, and it’s filtration efficiency reach 99.9%.
As the filtering precision of the main filter cartridge reach the indoor emission standards, clean air after filtration
can be directly discharged indoor through the air vents in the bottom of the purifier.
4. Power phase sequence instructions, short-circuit protection for lack of phase, with shut down protection
measures when too high temperature.
5. With large air volume, low noise and better capture effect. Suction hose uses the real anti-temperature, wear-
resistant compounded materials, without crack and damage to sparks. The filter element of the welding fume
extractor is produced using imported PTFE membrance filter material of high filtration precision and can filter out
welding fume of 0.1μm.
