What is the purpose of a mist collector?
When machines are operated in an industrial or scientific environment, the use of lubricants or cooling lubricants as well as high machine speeds can produce harmful oil or aerosol mists . These not only harm your laboratory or production staff, they may also cause damage to equipment, buildings and other equipment.
The so-called mist separators are used to separate or filter the dangerous aerosol vapours in gaseous media. The lubricant is separated by means of air or gases and then collected again for further use.

Mist separator: Function and design
The mode of operation of a mist separator can be classified according to the separation principle. In general, a distinction is made between four different modes of operation, which can also be combined in one device.
Gas scrubbers pass the aerosol mist to be cleaned through a scrubbing liquid. Particles and other harmful substances pass into the scrubbing liquid through the contact.
This type of separator consists of a system of filters with different filtering effects connected in series, through which the mist is passed. Depending on the size of the particles or pollutants, they remain trapped in one of the filters. The lubricant drips off the filter surface and can be processed and reused.
A centrifugal separator is mainly suitable for mists with larger particles. The aerosol particles are thrown out by a fast rotation and separated from the exhaust air.
With electrostats, the aerosols are electrostatically charged and collected on oppositely charged collectors. The lubricant can then run down the plates and be collected.
How is the dangerous aerosol mist produced?
Dangerous aerosol mists are often encountered in fast-moving machinery. For example, lubricated internal combustion engines produce so-called blow-by gases, which have to be vented off, carrying oil or lubricants with them. Lubricated compressors also carry lubricants into the medium to be compressed.
In the laboratory environment, vacuum pumps are often used in which the tightness and pumping effect are increased by suitable lubricants. Here, too, the pumped volume of the medium is contaminated with lubricant. The resulting aerosol vapours are hazardous to health and can cause irritation to the skin and eyes. The deposited lubricant film can also destroy machinery or even pose a fire hazard.
Types of mist separators
Depending on the variability of the hazardous substances to be extracted and the number of machines to be extracted, different separator models can be considered. These differ on the one hand in the mobility and performance of the systems, but may also have different operating principles.
This type of mist collector can be mounted directly on the machine in question, which operates with cooling lubricants or other lubricants. The direct connection ensures that all aerosol vapours do not escape but are fed directly to the filter. The capacity of the separator can be selected to suit the size of the machine.
Mobile harvesters with extraction arm
Mobile harvesters are mounted on a trolley and can thus be easily transported to where they are needed. The extraction takes place via an extraction arm which is placed above the machine in question. Thus, this system can be flexibly combined with almost any machine. The distance between the machine and the extraction unit is, however, greater than with directly mounted mist extractors.
The hall extraction system is used for the central cleaning of the room air and the removal of the cloud of mist that is often found there. The hall air is drawn in by a recirculation system and effectively cleaned of aerosol particles and pollutants. The filtered air can then be returned to the room air.
Central mist separator
Central mist separators are suitable for the parallel connection of several machines. Through a pipe system, these can be operated simultaneously and thus extracted at the same time. The separating effect can be selected to suit the size and number of machines to be extracted.
