In industrial machining processes, the generation of oil smoke and fine oil mist is unavoidable. Without effective collection and filtration, these airborne contaminants pose serious health risks to workers, increasing the likelihood of respiratory diseases and occupational illnesses. At the same time, accumulated oil smoke not only pollutes the work environment and degrades air quality but also accelerates wear and malfunction of machinery, resulting in higher maintenance costs. Furthermore, the presence of flammable oil mist increases the risk of fire hazards, endangering factory safety. To ensure stable, safe production that complies with regulations, oil smoke collection systems have become an essential protective measure in modern smart manufacturing—safeguarding employee health while enhancing equipment efficiency and environmental quality.
