         Having spent 30 years in the energy field
         reviewing many industrial applications, I have to
         admit the actual generation and distribution of
         compressed air has commonly been the first and
         prominent element of reviewing such systems.
         This has often been the extent of advice and
         recommendations to my clients.


         More  recently,  I’ve  been  made  aware  of
         significant  technology  advances  in  the
         component compressed air reductions that are
         now available from manufacturers that can have  palletizers, jigs and component placement. The  Modern vacuum ejectors employ a sensing
