Double Entry Fume Hood
The Iroquois double entry fume hood has two opposing sashes to allow demonstrations from either side of the fume hood. Typical installations are on island casework or in a wall separating the classroom and prep room. The sash counterweights are concealed in either sidewall, or alternatively in one sidewall to provide for a viewing window or plumbing fixtures in the opposing wall. Due to the minimal baffling and uncontrolled air flow with both sashes open, the optional sash interlock is recommended to permit only one sash to be opened at a time.
