Under the negative pressure, the welding fume enters the main body of the welding fume purifier from the suction arm. The flame arrester at the air inlet keeps the welding spark. The fume gas enters the purification room of the main body of the welding fume purifier, and the high-efficiency filter element filters the tiny fume and dust particles in the purification room of the welding fume purifier The clean gas is filtered and purified by the filter element and then enters the clean room of the welding smoke purifier equipment. The clean air is further absorbed and purified by the filter and then discharged through the air outlet. Exhaust gas can meet the national requirements of indoor gas emission standards!
