Oil mist is a very fine mixture of a gas, usually air, and an oily liquid. Oil mist is a by-product of various production processes.
It occurs when oily or pasty lubricants, separating agents or coolants are used in the production process. This is usually during production steps where high temperatures or strong friction occur, such as machining, milling or casting of metal. Friction or heat causes tiny liquid droplets and particles to be released into the exhaust air stream as aerosol or smoke. The emerging oil mist is highly harmful and, in case of incorrect filtration, can form residues on machines and electronics, which in turn can lead to failure of the production machine.
Therefore, it is essential to efficiently extract the oil mist from the production exhaust air (see also: oil separation). Thanks to the modular design, the high-performance exhaust air filtration systems by KMA Umwelttechnik are especially adapted to the challenges of oil mist filtration. The energy-efficient electrostatic precipitator purifies the production exhaust air using electrostatic charging. Depending on requirements or customer wishes, additional filter components can be added or retrofitted, for example for odor separation or heat recovery. For the filtration of particularly heavy oil mist, KMA offers a proven combination of electrostatic precipitator and gas scrubber.
