Monthly Dust Monitor Vacuum Pump Check (FAMIS #12987)
Hugh & Jeff B.,

   Checked the dust monitor vacuum pumps. Adjusted the vacuum pressure at End-Y; all others were within spec. All pump temperatures are within spec. 

   There is a bit of carbon build up on the exhaust muffler on the End-Y pump. Will continue to monitor this pump for a future rebuild.
