Vertical Laminar Airflow Fume Hood
Offering personnel, product, and environmental protection.
The FumeGard NU-156 is designed and tested 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 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.
IS HIGHLY CORROSIVE RESISTANT
HAS HIGH TEMPERATURE AND TENSILE STRENGTH, EXCELLENT RESISTANCE TO ORGANIC SOLVENTS, DEGREASING AGENTS, AND ELECTROLYTIC ATTACK.
Conventional Fume Hood
The FumeGard NU-162 has a single piece airfoil across the bottom of the work access opening. As the sash is lowered, the face velocity increases rapidly. Fumes, gases, vapors, aerosols, and particulate are drawn through vents by an exterior exhaust duct. “Double wall” construction forms the plumbing chase for routing and connecting all services. This compartment is under negative pressure to minimize fume build-up.
DEPENDING UPON YOUR REQUIREMENT
OTHER THERMOPLASTICS MAY BE USED.
POLYVINYL CHLORIDE (PVC), CHLORINATED POLYVINYL CHLORIDE (CPVC), FLAME RETARDANT POLYPROPYLENE, POLYVINYLIDENE FLUORIDE (PVDF), HIGH DENSITY POLYETHYLENE (HDPE), AND TFE-TETRAFLUOROETHYLENE (TEFLON®) ARE AVAILABLE.
By-Pass Fume Hood
FumeGard NU-164 has a by-pass that maintains a constant volume of airflow. As the sash is closed, air is by-passed at the top of the hood, causing the hood face velocity to increase much more slowly than a conventional fume hood. A deflector vane across the bottom of the opening directs airflow across the work surface. This provides a permanent opening even when the sash is closed. Most of the exhausted air enters the fume hood through the by-pass.
VIRTUALLY METAL FREE
SERVICE REQUIREMENTS AND ELECTRICAL COMPONENTS ARE KEPT
SEPARATE FROM THE WORK ZONE AND PLENUM TO AVOID CORROSION.
EVEN THE DOOR HINGES AND SCREWS ARE MADE FROM POLYPROPYLENE.
ACID STORAGE CABINETS
NuAire Acid Storage Cabinets are constructed from stress relieved white polypropylene. The outer cabinet shell, kick plate, and shelves are constructed from 1⁄2 inch (13 mm) polypropylene. The NU-53 Tall Double Door Cabinet has one fixed and two adjustable shelves with drip-proof lips. Cabinets come with a capped vent placed at the customer’s specified location.
ALL CASEWORK IS MANUFACTURED USING
STRESS-RELIEVED, FULLY SEAM-WELDED,
WALLS AND FLOORS ARE REINFORCED WHERE REQUIRED TO MAINTAIN STRUCTURAL INTEGRITY. DOORS ARE READILY REMOVABLE AND HINGES EASILY REPLACEABLE. SLIDING WALL CASE DOORS MAY USE GLASS, LEXAN™ OR SOLID POLYPROPYLENE.
NuAire polypropylene casework is designed to conform to a wide variety of unique customer requirements. Modifications, additions, optional accessories or customer-designed products can be fabricated to meet the specific needs of your laboratory application.
