Double Entry Fume Hood

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.

Standard features include:

  • Welded superstructure for structural rigidity and design flexibility to accommodate custom hood sizes and features
  • Single top exhaust baffle
  • Wide Post (flat front) side post design can accept up to two electrical and four plumbing fixtures on one post of each sash

  • Stainless steel sash guides, duct collar
  • Sash/counterweight pulley system utilizing six 2 ½”-diameter pulleys for smooth, dependable operation
  • Vapor-proof incandescent light fixture (bulb not included)

  • Liner material – ¼” composite stone; ¼” white epoxy-coated composite stone; ¼” poly-resin – all non-asbestos
  • Sash interlock – automatically locks one sash closed when other sash is open
  • Electrical switches and receptacles.  Also explosion-proof lighting and fixtures available.
