Model EDU fume hood is well-used in classroom demonstrations and training. It is completely self-contained, provides all around visibility, and is easily moved from lab to lab. The ductless design allows easy installation and the base is mounted on large heavy duty wheels. Unit height is 77.5 inches, which allows it to easily pass through a standard door. The multi-layered EDU filter has been independently tested to have 99.9% filtration efficiency for chemicals normally found in a typical chemistry curriculum. These units exceed OSHA, ANSI, BSI and AFNOR Safety Standards.
