** Blast Room ventilation should be maintained at 100 fpm lateral flow through the booth per the USAF base Bio-Environmental office**

- 15’ W x 10’ H =150 sq. feet x 100 fpm = 15,000 cfm dust collector need to maintain 100 fpm through the booth. AFG always over sizes the dust collector to maintain the 100 fpm as the filters load with dust.

-The abatement of chromium left from the removal of the current blast enclosure will be the responsibility of the contractor.
