Welding smoke collector central purification system is suitable for multi-station carbon dioxide welding, MAG welding, gas melting and other flue gas production sites. The main components include: welding arm, 2-3m long flexible universal dust arm, high temperature vacuum hose, dust cover (with air volume control valve), fire net, cyclone, flame retardant high efficiency coated filter dust Equipment, fans and control boxes. Advantage: 1.Equipment with a dedicated turbo fan, to prevent the motor burned anti-overload circuit, high security, stable performance. 2.Filter cartridge imported PTFE porous membrane filter, long life, you can absorb the dust particles below 0.1μm, wet and sticky dust has a good filter effect. 3.All day automatic independent pulse control system, according to the conditions automatically detect the pressure value, according to the mediation value automatically adjust the injection time and savings compressed air time. Filter with a full range of automatic anti-blowing cleaning, so that the filter surface cleaning more thoroughly and clean, in order to always ensure that the dust collector has a constant suction capacity; air compressor part of the high pressure hose connection, the bottom of the high pressure intake, to ensure that the purifier In good working condition. 4,Use of 360 degrees can be free to move the universal suction arm, smoke from the smoke at the place to absorb smoke, greatly improving the collection rate of soot to ensure the health of operators. 5.Purifier supplies stable performance, easy to replace. Work in the smoke generated by the suction hood inhalation smoke dust purifier, first through the first layer of the defibrillator fire net, the large particles and grinding of the Mars particles can be separated from the trapped, the initial filtered air and then into the first The second layer of settling room, the settlement of the indoor protective board to its diversion and to avoid residual Mars directly into the main filter; shunt dust and then into the third layer of the main filter for the ultimate purification, the main filter up to 99.9% , Due to the high efficiency of the main filter can reach the indoor discharge standards, filtered clean air through the bottom of the purifier directly discharged to the indoor circulation.
