The industrial air purifier is mainly suitable for CNC machine tools and laser engraving machines. Generally, the machine is equipped with a filter, and a large amount of smoke and dust will be effectively filtered through its cotton, activated carbon and aluminum alloy filters. The filtering system has multiple filtering "stages". Each stage is responsible for specific work. The first phase removes the largest particles. The Monport air purifier laser fume extractor filters out toxic particles and various bad smells in the smoke through a four layer filtering system.
