The Aire Stream fume hood from Hemco Corp, Independence, Mo, is constructed entirely of chemical-resistant, flame-retardant, non-metallic composite resins, and features a “unitized” construction that does not require screws, bolts, rivets, or metallic hardware for assembly. The unit’s fume chamber is molded in one piece, with all corners coved for easy cleaning and light reflectivity. The series of fume hoods is UL-1805 certified and is offered in 48-inch, 60-inch, 72-inch, and 96-inch widths in either constant air volume or restricted bypass models. Hoods are equipped with a 36-inch extended view height and a slotted rear VaraFlow baffle system, which directs airflow through the fume chamber to the exhaust outlet. The series also includes an aerodynamic sash lift with a perforated air-sweep feature and molded-in belled outlet collar for reduced airflow resistance. The hood is shipped completely assembled and can include a wide selection of accessories that can be factory installed to meet specific needs. For more information, visit Hemco.
