Walk-In Hood
Automatic Sash Closer
The Iroquois walk-in is a floor-mounted hood designed to handle large laboratory equipment with roll-in accessibility. The full airfoil design of the LA-series side posts promotes smooth airflow around the sash perimeter. Wide Post (flat front) and Slimline (thin wall) post styles are also available. Two independent full-framed vertical rising sashes are standard equipment. Our distillation hood, a shorter version of the walk-in, can be floor- or low table-mounted. Drawing from a half-century of hood-making experience, we build hoods to accommodate almost every variety of apparatus and procedure.
