Virtually Metal Free    All FumeGard cabinets are virtually metal free and do not use nylon components. “Double wall” construction forms the plumbing chase for the routing and connection of all services required including electrical outlets. The sloped bottom polypropylene sink basin and strainer are fabricated from ¼ inch (6 mm) polypropylene. Access panels are provided for front maintenance of HEPA filters, services, electronic systems, and counterweight balance system. The window counterbalance contains metallic weights, but is encased in PVC. Metallic components, such as the fluorescent lighting, are fully encased in nonmetallic materials. Drawers, drawer guides, sliding window components, drawer pulls, handles, hinges, and screws are also manufactured using polypropylene.   

Setting the Performance Standard    The FumeGard NU-156 is designed and tested to meet product and personnel containment performance as established by NSF Standard No. 49 for Biological Safety Cabinets. These cabinets meet or exceed ISO Standard 14644-1, Class 10 air quality conditions, and have been independently tested for containment properties in accordance to ASHRAE Standard 110-1995 for Fume Hoods.   

TruLaminar Airflow    Unidirectional airflow moving along parallel flow lines at a constant velocity of 60 fpm (0.30 m/s) minimizes air turbulence within the work zone lessening the chance for cross contamination.   

Dynamic Air Barrier    Strong inflow air velocity of 105 fpm (0.53 m/s) through a 10"" (254 mm) access opening creates maximum personnel protection.   

HEPEX™ Zero Leak Airflow System    Constructed almost entirely of polypropylene, this fume hood contains the HEPEX™ Zero Leak Airflow System, available only from NuAire. The HEPEX™ system prevents uneven particulate loading by eliminating direct blasts to the HEPA filter, dispensing air over 100% of the surface. The system surrounds positive pressure airflow chambers and ducts with negative air pressure relative to the laboratory. This limits the possibility of leaks and guards against filter failure.   

Applications for All    NuAire polypropylene products have been used in Chemical Engineering, Electrical Engineering, Material Science, Environmental Toxic Analysis, Analytical Chemistry, Metallurgy, Water Treatment Facilities, Toxicology, Trace Metal Analysis, Marine Science, Waste Management, Soil Science, Semiconductor, and more.
