Ducted Fume Hoods — Fume Hoods
Ducted hoods exhaust fumes to the outside and remain the standard choice for general chemistry. We build constant-volume bypass and VAV hoods, walk-in hoods for large apparatus, benchtop units and distillation hoods with a low work surface. Containment is type-tested to EN 14175-3, and on-site performance can be verified by ASHRAE 110 or EN 14175-4.
