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.
