Message-ID: <3E6D3CD4.DF4338E4@snf.stanford.edu>

Tylan1-4, wbgaas and ag4108 users,

HEPA air to tylan, bank 1 furnaces (tylan1-4), wbgaas and the ag4108
will interrupted on Tuesday, March 18, from 7:00am to 2:00pm. Facilities
will be installing a new variable speed drive controller for the
transfer fan which supplies this area. HEPA air flow will be reduced to
make-up air flow only (about 10-20% of normal flow). The wet bench
exhaust flow will not be affected by this action. Users with a high
sensitivity to particle contamination are advised to not load or unload
furnaces during the shutdown time.

Thanks for your help and patience,

Dick
