• Description:
  The performance of an air cleaner was evaluated for controlling mist generated during the production of transmission parts at Sauer Sundstrand Company (SIC-3594), Ames, Iowa. Aerosol instrumentation was used to quantitatively evaluate size dependent mist generation of a synthetic metalworking fluid. During the machining operations the metalworking fluid was pumped through the orifices at a pressure of 800 pounds per square inch, creating a very fine mist. The air cleaner that was used successfully reduced the concentration of the aerosol, removing most particles greater than 4 micrometers, which accounted for 90% of the aerosol mass. The authors note that in selecting air cleaning equipment, the size distribution of the air contaminant is a most important consideration. The air treated by the air cleaner was even cleaner than the general atmospheric air at the facility being studied. If conditions were to change such that the size distribution of the aerosol were to shift to a smaller size, additional measures may be needed to control mist emissions from these machines. A problem did arise concerning drainage form the air cleaner, creating a new source of mist emissions. This should be taken care of through preventive maintenance procedures.
