Applications: Machinery Factory,Punching Factory,Preserved Fruit Factory,Ceramic Factory,Turbo Power Plant,Discharge Processing Factory,Glass finishing Factory Petrochemical Processing Feature list: ?Low Vibration Frequency, No Effecting Main Engine A vertical model main engine using aerodynamics principle, vibration is vanished of the action upward. Operating oil collector causes no effect on the main engine. ?Low Noise Driven directly by LONG-GOOD low noise engine. Streamline shape designed internal wall makes wind resistance less and low noise. ?Effective Filtering, Less Energy Needed High wind volume (15m3/min) exhales oil mist quickly. Two-step designed filter. Stainless filter (first-step) filters most cutting oil mist. Remaining oil mist sticking to the inner parts enable filter (second-step) to perform more ?No Oil, No Pollution Using oil-resistant sealing on connect points, no worry of oil mist leaking. Blades contact no internal parts while spinning, no lubricating oil needed. Guaranteed no oil needed. ?Rigid & Durable Body and impeller made of aluminum alloy, once iron shavings and foreign matters enters, it will throw the foreign matters away from the turning center without damaging the machine body, which is more rigid and durable than other sheet-metal ones. ?Reliable and Easy Maintenance Except blades, LONG-GOOD oil mist collector is so reliable that it hardly needs any repairs. Axis sealing between engine and oil mist collector blocks no articles from entering. ?Top Quality With Serve-Well s 25- year of experience and strict quality control, all parts reach top quality demands. Function testing is done on "Every" oil mist collector in factory. http://www.serve-well.com/docs/eng/oil_property.htm
