Oil mist Eliminators Review

Oil Mist Eliminators trap or filter out oil mist created by machines before the mist is expelled into the ambient environment. Oil mist is created by machines mechanical action such as: vacuum pumps, compressor pumps, gears, transmissions, reciprocating engines, turbines, etc. Oil mist is a potential health and environmental hazard. Additionally, oil mist creates an oil build-up or residue on everything within the machineries environment.

There are several oil mist eliminator technologies utilized within industry. All technologies are piped, attached or mounted directly to capture oil mist ventilating from the machine. Most technologies also have features to return the trapped oil to the machine for reuse. Oil mist eliminator typically contain a filter system which condensates the oil from the mist and returns the oil to the machine. Many systems incorporate a pressure safety valve to prevent excessive pressure buildup within the mechanical system or the oil mist eliminator. For machines that create oil mist with other undesired contaminates a charcoal or other chemical absorbing technology may also be present to eliminate or prevent the chemicals from discharging the machine.

Some machines, such as oil-sealed pumps are used and are oil mist free and the need for an oil mist eliminator is not needed. When choosing an oil mist eliminator, the following should be considered and determined.

1.) Volume and capacity of oil mist: Oil mist eliminators have limitations as to how much gas can flow through them. Exceeding the rated or design limits of an oil mist eliminator is not recommended. Selecting or designing a oil mist eliminator for up to 3 time the expected run or operating capacity is recommend:

2.) Oil mist produced by a machine often contains more than oil but it also contains many other contaminants and harmful chemicals. Additional features that prevent exhaust of these contaminants should be included.

3) Consider the maintainability of any oil mist eliminator. Systems that require a new paper filter, or excessive routine maintenance should be avoided. Keep in mind that a low maintenance system may actually be more expensive, but costs less over the like cycle of the machine.
