the oil fume purifier mainly uses various technical means such as filtration systems, ionization systems, deodorization systems to purify the oil fume emitted by hotels, so that it meets the national environmental protection emission standards. the main working principle is to use the action of a high-voltage electric field to ionize the oil smoke molecules, and then concentrate them on the oil collecting plate through various methods such as electric shock and electrostatic force to purify the air, and ultimately achieve the purpose of fresh air.
