The Exposure System Control Cabinet controls ten separate functions.  Air and vacuum controls allow the user to balance the air flowing into the exposure chamber so as to maintain a net negative pressure in the chamber.  The air operated controls are:  master air, nebulizer, diluter, and by pass.  Vacuum operated functions are: Master vacuum, impactor, filter #1, filter #2, and chamber pressure.  With the exception of the master air and master vacuum each of the above controls are associated with a flow meter so that precise flow can be determined.  In addition to the previously mentioned functions, there is also a chamber pressure gauge which will alert users to changes in chamber pressure.  Pressure gauges also monitor impactor, filter #1 and filter #2 functions to easily determine if a restriction has occurred during the sampling process.
