The FumeGard NU-156 is constructed almost entirely of polypropylene or other thermoplastics. Metal usage is kept to an absolute minimum. Any necessary metal parts are coated with either epoxy or Teflon®.
The HEPEX™ Zero Leak Airflow system, which is available only from NuAire, results in quiet, uniform, and sterile down flow over the work zone. The HEPEX™ system also prevents uneven particulate loading by eliminating direct blower blasts to the HEPA filter, and dispensing air over 100% of the HEPA filter surface. The system surrounds all positive pressure airflow chambers and ducts with vacuum or negative air pressure relative to the laboratory. This limits the possibility of cabinet or gasket leaks and guards against HEPA filter failure.
The FumeGard NU-156 has been designed and tested by NuAire to meet product and personnel containment performance as established by National Sanitation Foundation Standard No. 49 for Biological Safety Cabinets. These cabinets meet or exceed Federal Standard 209e, Class 10 air quality conditions, and have been independently tested for containment properties in accordance to ASHRAE Standard 110-1995 for Fume Hoods.
