Incorporated with filtration systems to control exhaust emissions, UniFlow Clean Aire I hoods feature a filter housing that can be equipped with either HEPA and/or carbon filters to help meet environmental concerns and regulations according to the Clean Air Act. Contaminants are then filtered prior to exhausting to the outside, helping reduce pollution and avoiding the risk of contaminants re-entering the building through the air supply system. The filter housing is located on the fume hood. UniFlow Clean Aire I hoods can function as a Class 1 ductless hood for selected contaminants and procedures. They are available in 48”, 60”, 72”, and 96” models.
