 DW-BG wall-mounted smoke purifier 
 Welder in the working process to produce large amounts of harmful gases such as CO, CO2, SO2, H2S, and smoke lead and fluoride fumes. Long-term inhalation of welding harmful gases harmful to human health caused great harm, induced disability and even death. Thus, welding smoke control more and more attention has been paid. 
 Company R & D and production of mobile Electrostatic welding fume purifier, a large number used in a variety of welding processes, widely used in dispersion welding, automatic welding, CO2 gas shielded arc welding, TIG, and DC welding a variety of workplaces, deep well received by customers. 
 ■ How it works: 
 Welding fume purifier mask inhalation after smoking, through the porous filter, coarse filter, re-entering the ionization region of the plasma electric field of charged adsorption, absorption of soot particles are trapped, and harmful gases by ionization purification and ozone oxidation to accelerate the reaction into None harmful gases, the reduction by the purified gas, no dust, no odor, can be recycled emitted into the atmosphere. 
 ■ Characteristics: 
 The device has a fixed, mobile two structures can be arbitrarily chosen application areas. Equipment cleaning is simple, easy maintenance, low noise, low power consumption, and can easily adjust the position of the vacuum arm, easy to use. 

 Air volume :1200-1500m3 / h 
 Power: 0.75KW 
 Size: 620 * 540 * 940mm 
 The large particles isolated in the pre-filter, air import particulate filter (separation efficiency ≥ 99%), very fine gas and dust is separated out. Can be used for welding fumes, polishing dust, and other chemicals in the production process of filtration and purification. 
 The device is equipped with a high capacity and high vacuum blower to ensure the purification of high-volume traffic. 
 360 degrees of each standard configuration retractable hover 2-3 meters long universal suction arm can be sucked directly from the source of the dust to dust. 
 The devices are small, easy to install, and to ensure that very few maintenance needs in harsh conditions.
