Donaldson Torit Media and Centrifugal Mist Eliminators

by James Lee, Industrial Designer

Donaldson Torit provides mechanical media based oil mist eliminators including direct machine mount, vertical modular, horizontal modular, or central systems plus a compact direct mountable centrifugal separator.  Most of these mist eliminatorstorstorstorstorstorstorstors seem pretty typical of what you will find with any other industrial mist eliminator manufacturer.  Donaldson's main focus is making media filters for uses all over the world.  After having taken over Aercology's mist eliminators, anything that doesn't use media has been dropped.  Aercology, a company that was once focused on industrial air cleaning has become Donaldson's distribution channel for industrial media filters.

One interesting product Donaldson offers, is the Mini-Mist Collector designed for light duty CNC machining, grinding, turning, milling and drilling.  Single machine mist eliminators are popping up all over.  Donaldson's is a very light duty, direct mount media based smoke and mist eliminator.  Using media filtration allows this oil mist eliminator to operate on a wide variety of applications.  Adapting mechanical media filters for use in different vertical markets seems to be one of Donaldson's strengths.

Mechanical media filtration is a simple concept, a box with a fan blowing air through a series of woven media filters.  A minihelic gage senses air pressure before and after the filter, giving you an indication of when to change the filter.  Media filtration can be used for mist, smoke dust, fumes, vapors and odors from a variety of wet or dry  machining operations like grinding, rubber machining die casting or soldering.  Unfortunately, media filters must be discarded and replaced once fully used, making it an expensive option.  Also, results are not consistent because airflow slowly weakens as the filter goes from clean to clogged throughout its useful life.  Due to restricted airflow, media filters need a high powered fan that must keep up with the gradually increasing static pressure.  In most applications, it is less expensive to maintain and more efficient to use an electrostatic precipitator.  The media based Mini Mist would be a good all purpose, coolant mist eliminator for the owner of a very small shop with very light mist & smoke pollution who would prefer paying for occasional filter replacement instead of performing occasional precipitator cell cleaning.
