LabGardNU-677
Class II Type A2 Biosafety Cabinet
DESIGNED FOR ANIMAL PROCEDURES | 12 IN. (305mm) ACCESS FOR CAGES | ACCESSIBLE BACK WALL PREFILTER | ADJUSTABLE BASE WITH CASTORS
The NU-677 is tailor-made for work in a vivarium by integrating an NSF-listed 12” (305mm) work access opening for cage access, castors and pull bars for mobility, and height adjustability for user ergonomics. This design also rises to the unique challenges of controlling airflow in a particulate-heavy environment. An accessible pre-filter in the back wall prescreens larger contaminants to protect the main HEPA filters. The DC ECM motor economizes energy and evenly distributes laminar downflow through a flexible plenum and provides enough power to overcome HEPA filter saturation. The work zone side and back walls are constructed from stainless steel for easy cleanability and surround a unified, flat work surface. Users can adjust the cabinet’s height at the press of a button and easily monitor cabinet performance through the Aeromax™ control system that visualizes pressure in the cabinet’s internal airflow plenum. The NU-677 provides containment meeting the NSF/ANSI 49 standard followed in most of the Americas.

AEROMAX CONTROL SYSTEM
The AeroMax control system visualizes airflow plenum pressure through a series of multicolored lights and activates both an audible and visual alarm whenever cabinet performance departs from normal parameters.
Powerful Yet Quiet
Ultra High Efficiency Motor
A single DC ECM motor with a precision-engineered forward curved fan powers airflow through the biosafety cabinet. The ultra-high efficiency motor lowers energy costs and reduces noise pollution but is powerful enough to extend filter life. The one motor design allows for easy certification and airflow balancing. In addition, it provides enough power to compensate for HEPA filter loading, reducing filter changes and lowering the total ownership cost.
WHERE CONTAINMENT MEETS ERGONOMICS.
12-inch nsf listed opening
When working with cages in a vivarium, not just any cabinet work access opening will do. However, if work may involve biohazards there is also no room to compromise on containment. The NSF-listed 12 inch (305mm) work access opening offers containment that is comfortable and practical.
WHEN HEPA FILTERS CALL FOR BACK UP.
BACKWALL PREFILTER access
A normal biosafety cabinet’s HEPA filters may not last long in a vivarium, where hair and dander can more quickly saturate them. That is, unless the cabinet is adapted for this particular environment by using a pre-filter to strain out the larger elements and leave the HEPA filters to contend with smaller particulate. The backwall placement of this pre-filter makes it easy to remove and maintain as needed.
