Monthly Dust Monitor Vacuum Pump Checks (FAMIS #7930)

    All three vacuum pumps (EY, EX, CS) are running well. Temperatures were all less than 150f. Made air bleed adjustments at End-X and the corner station.

   Note: There is carbon dust accumulation on the muffler and the output filter port on the corner station pump. This is a sign of late stage wear on the vanes. There is no spare for this pump, so it will need rebuilding in the near future.
