These ductless fume hoods feature molded fiberglass construction for self-containment and safety. Each hood is equipped with vapor-proof lights, integral carbon filter and internal blower. Small amounts of solvents, acids, and nuisance odors are adsorbed by the carbon and the cleaned air returned to the room. Installation does not require access to ventilation ducts and saves on energy, since a large volume external blower is not necessary. Order work surface and base separately.
