Monthly Dust Monitor Vacuum Pump Check

Both end station pumps running smoothly. The corner station pump (1194) must have over heated and kicked the breaker. One of the felt filters disentigrated and clogged the filter/muffler. This was cleaned out and put back together. A newer felt filter was added. The graphite veins seemed to be in fair condition. Pump 1194 was put back into service. I will check to see if it continues to run smoothly this after noon. More rebuild kits need to be ordered.
