Model NU-156/E Series
Manufactured By:
Nuaire, Inc. - Plymouth, Minnesota
1.0 General Information
1.1 Description
NuAire’s all Polypropylene Model NU-156/E FumeGard Vertical Laminar Flow Wet Process Fume Hood is a bench module
Fume Hood which utilizes the latest state-of-the-art technologies in laminar airflow design, materials and manufacturing
processes. The modular constructed Fume Hood can be used anywhere space permits where product (work-in-process)
and personnel protection are required for chemical research, microelectronics, semi-conductor design/development and/or
production assembly processes. Bench Fume Hoods consist of a single piece construction and can be placed on a customer
bench or on a special option polypropylene base provided for the Fume Hood. A significant number of design innovations
give the NuAire laminar flow equipment superior performance qualities in airflow, lighting, noise levels and vibration. In
addition, NuAire’s “Narrow Line Design” technique achieves excellent appearance and ruggedness through the use of large
modular components, reinforced construction techniques and contrasting color schemes.
The Model NU-156/E FumeGard Vertical Laminar Flow Clean Air Polypropylene Wet Process Fume Hood is a product
resulting from the development of the “laminar” flow principle, the application of environmental controls in the fields of
biological research or chemical containment and the necessity to provide a chemically inert and resistant work space. The
wet process fume hood, when used with proper laboratory technique, is an effective laboratory aid in obtaining optimum
control over product quality while reducing the potential for exposure of both product and personnel to airborne
particulate chemical agents as well as fumes and vapors generated as a result of work-in-progress operations.
The NU-156/E FumeGard has been designed and tested to the performance criteria as established by the NSF/ANSI 49 for
Biosafety Cabinets for personnel, product containment performance. In addition, the NU-156/E meets or exceeds ISO 5 air
quality conditions. The NU-156/E has been independently tested by Knutson Ventilation; Minneapolis, MN for its
containment properties (i.e. personnel protection) to ASHRAE Standard 110-2016 for Fume Hoods, with a Performance
Hood Rating of AM<0.1 (instrument’s limit of detection) when operating at a sash height of 10 inches (254mm).
