Someone gave the museum what we call a large vacuum pump. It has a 25 hp
motor, is about 18" on a side, and says in large bold letters 40 with
the words Two Stages below it. The mfger seems to be Edwards. It looks
like it would evacuate all the air from a large room. I may have been
used in the semiconductor industry. Any suggestions on how we might use
it for an exhibit?
