FPM. Lower face velocity may compromise user safety.

The Trace Metals Fume Hood incorporates (4) horizontal sliding sashes on (2) tracks, the maximum opening is 50%. which
corresponds to a 50% savings in CFM. Should the entire front opening need to be accessed the horizontal sliding panels
may be removed for equipment set up
