CleanAire II Ductless Hoods are available in 24-, 30-, 35-, and 47-inch models. The hoods feature a built-in carbon filtration system to adsorb non-toxic fumes and odors. The hood is equipped with an integral blower, vapor proof light, fan and light switches. The hood superstructure is constructed of chemical and flame resistant, non-metallic, composite resin with a molded one-piece seamless interior fume chamber. A vertical sliding clear acrylic sash protects the user and contains the process fumes. The carbon filter that is included adsorbs the fumes and then re-circulates the air back to the laboratory. Hood is shipped completely assembled and ready for operation.
