The lithium battery production line involves a number of dust treatment processes. This case is listed as the collection and purification of flammable and explosive smoke and dust generated by laser welding of aluminum parts of lithium batteries for a well-known domestic customer. Using our PA-30LT-EX explosion-proof dust collector, this model has large air volume and high negative pressure, as well as the explosion-proof certification of the whole machine. It can quickly remove the smoke and dust generated in the production process, prevent the smoke and dust from spreading to the workshop environment, and reduce the risk of explosion.
