EFDB-FG9-NW25 Small Oil Mist Filter (2024)

FAQs

What does an oil mist filter do? ›

When contaminated air passed through the filter media, oil particles are attracted to the oleophobic fibers. The oil droplets collide with the fiber and accumulate. When drops become larger, they are heavy enough to fall down to the base where it can be collected or drained back to the machine tool sump.

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.

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.

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.

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.
