All Mist Eliminators - Comprehensive List From Major Manufacturers

Mist eliminators are machines that filter and collect coolant, oil mist and smoke created by metalworking industrial equipment such as: screw machines, surface and centerless grinders, chuckers, bar machines, CNC machining centers, turning lathes, parts cleaning systems, quenching, high-fluid pressure machining and other processes.  Basically, anything that uses metal cutting fluids requires a mist eliminator to address air pollution.  The table below shows a full list of all the oil mist eliminators and coolant mist eliminators that have been reviewed throughout this site.  Other pages with more specific categories have shorter tables with fewer mist eliminators, making it easier to compare them.  You will find more background information below the comparison chart, as well as product reviews or opinions from our panel of mist eliminator experts.  More Information

There are three different kinds of mist eliminator filtration technology which can be used in a variety of configurations.  The types of filtration are media, centrifugal separation, and electrostatic precipitation (ESP).  A media filter is the most basic concept.  Contaminated air is passed through woven material.  Air passes through, while coolant, oil mist and smoke particles are caught on the filter.  Furnace filters and clothes dryer lint traps are examples of media filters.  Centrifugal separators spin a drum with an inner and outer chamber.  Air is sucked up through the middle of the drum while oil and contaminants are thrown to the outer chamber for drainage.  In an electrostatic precipitator, airflow passes through an ionizer then collection cell.  The ionizer gives any contaminants a static electrical charge, (same concept as rubbing sucks on carpet on a dry day).  Charged contaminants stick to collection plates and continuously drain oil or fluid.  Electrostatic precipitators are the latest mist eliminator technology and often the best suited for collecting metalworking fluids.


Comparing Mist Eliminator Technology

by James Lee, Industrial Product Designer

Generally, the simplest way to eliminate metal working fluid mist is to use a small coolant or oil mist eliminator at each machine center.  I prefer this method over using one large coolant mist eliminator ducted to several machines.  The main reason being air handling can be difficult to balance for multiple machining centers.  It's much easier to adjust airflow going from one machine to one mist eliminator than to balance the airflow from multiple machines to one big central mist eliminator.  Adjusting the airflow at one station can affect all stations.  Plus, metal cutting fluid can be returned from a machine mounted mist eliminator directly to the machine center.  When possible, my preferred method is to use a machine mounted mist eliminator with a variable speed control, so as to use as little CFM as needed to pull smoke and mist out of the machine enclosure.  Its like driving a car, you baby it and keep RPMs down for fuel efficiency and low maintenance.

Media, centrifugal, or electrostatic?  Manufacturers make comparable mist eliminators with either media filters and electrostatic filters and leave it to you to choose your technology.  Right away I will tell you my preference for industrial mist eliminators is electrostatic precipitation.  When the technology first came out 30 some years ago, there was a lot of buzz about it.  People were excited about them and used them everywhere... even in the wrong applications.  The biggest problem was that the new technology was being applied in mass quantity before all the bugs were worked out.  The main troublemaker was an unsophisticated power supply that was unable to deal with any kind of shorting or irregular loading on the cells.  Since then, technology has come a long way.  Available power supplies today, keep these machines online and safe. 

Electrostatic precipitators that are made now, provide continuous air flow while pulling 95%-97% of 0.3 micron particles out of the air passing through it.  For media to filter out particles, it has to physically block the airflow.  As particles become trapped in the media, they make the filter more dense and able to stop even more particles.  As this happens, there is less porous space for air to flow through, making it hard for the motor to maintain CFM.  ESP never has this problem - collection blades are spaced far enough apart to allow airflow even after the blades are completely covered with contaminant.  If they do get caked with contaminants, they make a bug zap sound that tells you its time to clean the cell.  You can minimize downtime by keeping a spare clean cell to rotate out with the dirty cells.  Your mist eliminator can be back online with a clean cell in 5 minutes.  This makes preventative maintenance minimal.  In most situations, collections cells only require washing once a year, if ever.

As for centrifugal separator mist eliminators, maintenance is the biggest downfall.  These things have a lot of parts that spin very fast.  Contaminants are pulled through the spinning parts and flung outward to collect along the wall of the outer chamber.  Contaminant sticks to the parts and causes them to go out of balance.  The result is the same as a washing machine in spin cycle with an unbalanced load of clothes... except at extremely high RPM.  This can be a problem for precise tooling.  Vibration or shaking from a centrifugal mist eliminator will transfer to the machine it is mounted to.  Unless they are constantly cleaned, centrifugal mist eliminators will eventually shake themselves apart.

What about HEPA?  Everyone's heard of HEPA, but here's what it really does.  HEPA (High Efficiency Particulate Air Filters) is a media filter that can be put over the exhaust of any mist eliminator to trap very fine particles.  Technically HEPA filters are capable of preventing 99.97% of particles 0.3 microns or larger from passing through.  So your HEPA filter cuts out all oil smoke, plus other common contaminants like pollen, mold spores, bacteria, fly ash, cement dust, heavy dust, settling dust, most smog, most tobacco smoke, and most soot.  The only problem with HEPA is air restriction.  I can give you a brick wall and call it HEPA.  Nothing's getting through there, not even air.  But as long as it stops 99.97% of particles 0.3 micron and larger, its considered HEPA. So be aware HEPA will make the blower work harder and drive up your electric bill.  Unfortunately, using any type of media filter for wet contaminant is not very efficient; it must be highly porous to catch the mist, but smoke and everything else will pass through, making a restrictive after-filter necessary. When using an ESP mist eliminator, generally a HEPA filter is not necessary, since most ESP cells capture 95% - 97% of wet or dry particles 0.3 microns and larger.  In fact, people who use electrostatic mist eliminators, such as the AQE MistBuster 500, in conjunction with a HEPA after-filter almost never change their HEPA because it barely gets dirty.  Most contaminant is caught by the ESP.
