Uniflow SE Aire Stream fume hoods from HEMCO Corporation are constructed from chemical-resistant, flame-retardant, nonmetallic composite resin materials with unitized construction that does not require screws, bolts, rivets or metallic hardware to assemble. The fume chamber is molded one-piece seamless with all corners coved for easy cleaning and light reflectivity. They are UL 1805 certified and are available in 48-, 60-, 72- and 96-inch widths in either constant air volume or restricted bypass models. They are equipped with a 36-inch-high extended view height, slotted rear VaraFlow baffle system, aerodynamic sash lift with perforated air-sweep, and molded-in belled outlet collar for reduced airflow resistance. Units are shipped completely assembled and can include a selection of accessories that can be factory installed to meet specific needs. Work surfaces in a variety of materials and a choice of base cabinets including acid or flammable storage are available. 816/796-2900; www.hemcocorp.com.
