FAQs

How does oil mist separator work? ›

An oil mist separator operates by using the coalescing effect inside a filtering unit. Oil-laden air is led into the filer by way of vacuum. A side channel vacuum pump creates the suction which can be adjusted manually via an additional air valve.

High-strength mist filters are ideal for shooting in low lighting conditions when a visible light source is present (e.g., a street light, a candle, etc.). That's because they will add a soft glow around the light source, enrich the shadows, and reduce the contrast between highlights and shadows.

The main limitations and/or disadvantages of oil mist lubrication are the lack of knowledge about the operation and the application of oil mist. Because airflow delivers the oil mist (oil particles) to the point of lubrication, the suspension of the oil particles is important.

The life of the mist filter depends on the process application. For most applications, you should change the mist filter element every six months. For applications which contaminate the rotary pump oil, this period will be reduced and must be determined from experience.

What is a Mist-Eliminator? Mist Eliminator separate out water, oil and particulates from the air by using a coalescing filter. Mist eliminators are a heavy-duty coalescing type filter that combine motion along with a barrier filter to remove particulates, condensate and oil from process air.

Without an oil separator on a car that spends a fair amount of time in high RPMs, oil can build up around the throttle body. This can cause the throttle body to trip a check engine light due to lack of response. The throttle body could also potentially get stuck open or closed, which isn't a good thing.

Oil mist is an aerosol mixture of very small oil droplets (one to five microns) suspended in air with the appearance of smoke. This mist is generated by passing compressed air through a venturi or vortex to siphon oil from a small central reservoir (Figure 1).

An Oil Mist Separator, also called Oil Mist Eliminator or demister, is the technical term for a filter system that is used where power generating engines or turbines operate, for example in power plants and refineries. To ensure trouble-free operation, the turbine bearings are lubricated with oil.

Mist eliminators remove visible oil vapor from the air stream of vents in lubricating oil systems of large, high-speed rotating equipment such as gas turbines, steam turbines, turbo compressors, turbo generators, reciprocating engines, high speed couplings and gear boxes.

The flow of oil mist supplies continuous lubrication to the bearings and passes onto a vent point. The excess oil mist must be contained and collected below the equipment for reuse or disposal.

What is the purpose of oil mist detector in main engine? ›

The detector constantly monitors the oil mist concentration in the crank case, indicates the mist level and, if the concentration is raised beyond a set point by the overheating of the bearings or any other cause, issues an alarm.

Examples include bearings of electric motors, pumps and compressors in many oil refineries and petrochemical plants¹; gears, cams, chains and sliding surfaces of machines in steel and paper mills; construction equipment and an increasing range of other industrial applications.
