 DW-JT Series smoke purification dedicated filter 
 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. 

 Filter is the core component of the smoke purification equipment, and its direct relationship to the purifying efficiency. 
 Smooth, hydrophobic PTFE membrane and flexible filter cleaning dust the better, and enable the filtration efficiency of 99.99%. 
 The filter options: 
 RH1A resistant flame-retardant composite fiber filter 
 RH2F peritoneal treatment of polyester fibers 
 The flame retardant filter is to add a flame retardant material inside the filter material so that it will not be lit when operating in the harsh environment of high temperature, Mars and other working conditions, increase filter life and high reliability. 
 Within the purification equipment in the cartridge type dust, dust concentration, high precision filter, the filter must have a certain fire performance, under such circumstances, our company has developed a specific product, which has a high filtration precision, large filtration area excellent performance. 
 Standard structural features: 
 A wide fold away design 
 2, ultra-high efficiency filter 
 3, opening at the top of the bottom opening / bottom of the back cover, with a reduced mounting holes 
 4, the flame retardancy 
 5, galvanized anti-rust metal structure 
 6, the rubber seal 

 Our company specializes in the production of various filters: special filter welding fumes purification; for activated carbon fiber filter; polished polishing powder recycling special filter; pewter clean special filter welding fumes; high temperature dust filter; peritoneal filter has been widely used production line recycling of raw materials, energy, cement, chemical, mechanical, printing, food, iron and steel smelting, glass, etc., purifying all kinds of welding shop smoke to purify the place, the larger dust particles on the environment requires a relatively high place. 

 Non-standard size cartridge can be customized according to customer circumstances.
