• Important: by incorporating Sash Management 1-2-3,

you are saving on overall energy costs, and protecting the fume hood user.

1. Recommended that hoods be used with sash 1/2 open

with face velocity of 80-100 fpm. Sash stop can be located

to suit. With lower sash closed and upper sash raised to the

1/2 open position the supply air cfm & static pressure are as

noted.

2. Sash in full open position should be for setup of apparatus

& maintenance service only. If design opening is at 1/2

open at 100 fpm, face velocity at full open would be

approximately 50 fpm. The recommended face velocity

for efficiency & safety is 80-100 fpm. Lower face velocity

may compromise user safety.

3. When hood is not in use, keep sash in closed position.
