During normal operation, room air enters through the front opening to provide personnel protection. Separately supplied HEPA-filtered downflow air moves vertically through the work chamber to provide product protection. Rather than recirculating air within the cabinet, the NU-560-600 directs all airflow through the exhaust filtration system and into a dedicated external exhaust connection. The cabinet's internal blower supplies the HEPA-filtered downflow air, while an external facility exhaust blower provides the suction required to remove the combined inflow and downflow air. The relationship between these two airflow systems is critical to containment performance. NuAire addresses this requirement through its TouchLink control system, digital exhaust flow grid, downflow sensor, and redundant exhaust failure interlocks. These systems help operators monitor cabinet performance and reduce the risk of unsafe operation if facility exhaust is lost. The NU-560-600 is therefore fundamentally different from a recirculating Type A2 biosafety cabinet and requires specialized installation, exhaust coordination, and certification. Why Choose the NuAire NU-560-600? The NuAire NU-560-600 is particularly attractive for laboratories that require both biological containment and complete external exhaust of cabinet airflow. Its Class II Type B2 design makes it suitable for certain specialized applications where recirculation of potentially contaminated air within the cabinet would be inappropriate. The large 6-foot work chamber provides ample room for laboratory equipment, reagent containers, sample racks, and complex preparation procedures. TouchLink controls continuously display important airflow parameters, helping operators recognize changing conditions and respond to alarms. The energy-efficient DC motor provides dependable downflow operation, while the redundant exhaust safety system helps protect against loss of facility exhaust. The stainless steel interior and removable work tray support routine cleaning, maintenance, and decontamination. For laboratories with appropriate facility exhaust infrastructure, the NU-560-600 offers a sophisticated containment solution combining total exhaust operation, intelligent monitoring, and substantial working space. Class II Type B2 Total Exhaust Technology The defining feature of the NuAire NU-560-600 is its 100% total exhaust airflow configuration. Unlike Class II Type A2 biosafety cabinets, which typically recirculate approximately 70% of their airflow, the NU-560-600 does not recirculate air within the cabinet. HEPA-filtered supply air enters the work chamber as vertical downflow. Room air simultaneously enters through the front opening, helping prevent potentially hazardous aerosols from escaping into the laboratory. Both airflow streams are drawn into the exhaust system and discharged through HEPA filtration to the facility's dedicated external exhaust system. This arrangement provides biological containment while preventing cabinet air from being recirculated internally. Because HEPA filtration removes particles but does not remove chemical vapors, the external exhaust system is essential for applications involving permitted quantities of volatile chemicals. The NU-560-600 should be selected based on a documented risk assessment, the substances being handled, and the facility's ventilation capabilities. Dedicated Facility Exhaust Requirements The NuAire NU-560-600 requires a properly engineered external exhaust system for operation. The manufacturer's published direct-connection exhaust requirement for the 6-foot model is approximately 1,275 CFM at 1.8 inches water gauge static pressure. The facility exhaust system must be capable of maintaining the required airflow under actual operating conditions, including ductwork resistance, exhaust filtration, building pressure, and other relevant factors. Unlike a Type A2 cabinet that may be able to discharge HEPA-filtered exhaust into the laboratory, the NU-560-600 cannot operate as a recirculating cabinet. The external exhaust blower must be properly coordinated and interlocked with the cabinet's internal blower. Facility engineering personnel should evaluate the proposed installation before purchasing or relocating the cabinet. For laboratories replacing an existing Type B2 cabinet, compatibility with the current exhaust system should be verified rather than assumed. TouchLink Electronic Control System The NuAire NU-560-600 incorporates the TouchLink electronic control system, designed to provide continuous monitoring of critical cabinet operating conditions. The touchscreen displays inflow velocity, downflow velocity, and exhaust airflow volume, giving operators access to important information about cabinet performance. The system communicates with the cabinet's airflow sensors and monitors the relationship between the internal downflow blower and the external exhaust system. TouchLink also provides alarm functions and supports protective responses to certain exhaust failures. For laboratories operating under documented quality systems, the ability to monitor and review cabinet performance can be particularly valuable. The TouchLink interface includes performance-history capabilities, with recent operating data available on-screen and additional historical information available through USB export. These features can support equipment monitoring, maintenance records, and quality-assurance procedures. Redundant Exhaust Failure Protection Loss of facility exhaust is one of the most important operating risks associated with a Class II Type B2 biosafety cabinet. If the external exhaust system fails while the cabinet's internal supply blower continues operating, protective airflow conditions may be compromised. The NU-560-600 incorporates redundant exhaust monitoring and protective interlocks designed to address this risk. A digital differential-pressure exhaust flow grid monitors exhaust performance and communicates with the TouchLink controller. A separate mechanical pressure switch provides an additional level of protection. The cabinet's control system is designed to shut down the internal downflow blower when an exhaust failure is detected, reducing the possibility of air being forced outward through the front opening. These protective systems must be maintained and verified as part of routine service and field certification. Digital Exhaust Flow Grid & Downflow Monitoring The NU-560-600 incorporates a digital exhaust flow grid that monitors exhaust airflow through differential-pressure measurement. The TouchLink system uses this information to display exhaust volume and derive relevant inflow information. A separate downflow sensor monitors the velocity of clean air moving through the work chamber. Together, these monitoring systems provide important information about the cabinet's protective airflow. For pharmaceutical research, biotechnology, and other demanding laboratory applications, continuous airflow monitoring can help operators identify operating problems before they affect laboratory procedures. These systems complement, but do not replace, independent field certification. Energy-Efficient DC Motor The NuAire LabGard ES TE NU-560-600 incorporates a DC electronically commutated motor designed to provide efficient and dependable downflow airflow. The motor supplies HEPA-filtered air to the work chamber and compensates for increasing resistance as the supply HEPA filter accumulates particulate material. The motor's efficiency is particularly valuable in a large 6-foot cabinet where substantial airflow must be maintained. However, total exhaust cabinets also impose significant demands on building ventilation systems. Overall operating costs should therefore account for the dedicated exhaust blower, conditioned replacement air, heating, cooling, and ongoing certification requirements. For laboratories considering a refurbished Type B2 cabinet, evaluating these facility-related costs is an important part of equipment selection. HEPA Filtration & HEPEX Filter-Sealing System The NU-560-600 incorporates separate supply and exhaust HEPA filters designed to provide 99.99% filtration efficiency at 0.3 microns. The supply HEPA filter provides clean vertical downflow air within the work chamber. The exhaust HEPA filter removes airborne particles from cabinet exhaust before the air enters the facility exhaust system. NuAire's HEPEX filter-sealing system uses spring-loaded sealing components designed to maintain secure filter installation and simplify servicing. The cabinet incorporates a 3-inch supply HEPA filter and an approximately 11.5-inch exhaust HEPA filter in the standard configuration. Proper filter installation, integrity testing, and certification are essential to maintaining the cabinet's intended containment performance. Because HEPA filters do not remove chemical vapors, the external exhaust system remains essential when handling permitted volatile chemical substances. Stainless Steel Construction & Cleaning The NU-560-600 incorporates welded Type 304 stainless steel construction designed for durability, containment, and routine laboratory cleaning. The work chamber uses a single-piece stainless steel arrangement along the side and rear walls, minimizing seams and supporting cleanability. The cabinet also incorporates a one-piece dished stainless steel work tray designed to contain minor spills. A prop rod allows the tray to be raised for access to areas beneath the working surface. These features are especially useful in pharmaceutical research, biotechnology, and biological laboratories where cleaning and decontamination are performed frequently. The cabinet also incorporates a front-right drain valve and provisions for laboratory service connections. Cleaning and decontamination procedures should be selected according to the biological agents, chemicals, and materials handled within the cabinet. Large 6-Foot Work Chamber The NuAire NU-560-600 provides approximately 70.4 inches of interior width, 26 inches of depth, and 25.2 inches of height. This spacious work chamber accommodates multiple sample racks, culture vessels, reagent containers, and compatible laboratory instruments. The additional width can be particularly valuable for specialized procedures requiring several work zones or multiple pieces of equipment inside the cabinet. Researchers should organize materials to avoid obstructing the front intake grille, rear airflow openings, or intended downflow pattern. The cabinet's 8-inch working sash opening must be maintained during normal biological procedures. NU-560-600 vs. NU-540-600: Type B2 vs. Type A2 The NuAire NU-560-600 and NU-540-600 are both nominal 6-foot Class II biological safety cabinets, but their airflow designs and installation requirements differ substantially. The NU-560-600 is a Class II Type B2 total exhaust cabinet that directs 100% of its airflow through an external exhaust system. The NU-540-600 is a Class II Type A2 cabinet that recirculates most of its airflow internally and can generally operate without direct facility exhaust for appropriate biological applications. The NU-560-600 is intended for laboratories requiring total exhaust containment, including certain procedures involving biological materials and permitted quantities of volatile chemicals or radionuclides. The NU-540-600 is generally more practical for routine cell culture, microbiology, and other biological procedures that do not require total exhaust. Selecting between these cabinets requires evaluating the laboratory's intended applications, biological risk assessment, chemical use, ventilation infrastructure, and operating costs. Common Applications The NuAire NU-560-600 is designed for specialized laboratory procedures requiring Class II Type B2 containment. Applications may include pharmaceutical research, biotechnology, drug preparation, microbiology, cell culture, vaccine research, and certain procedures involving biological materials combined with limited quantities of volatile chemicals or radionuclides. The cabinet may also be appropriate for certain specialized pharmaceutical preparation and research workflows where complete external exhaust is required. Use with hazardous chemicals or radionuclides must be evaluated through an appropriate risk assessment, including chemical compatibility, quantities, fire hazards, exhaust-system design, and applicable safety requirements. The NU-560-600 should not automatically be treated as a substitute for a chemical fume hood for all chemical applications. Ideal Laboratory Environments The NU-560-600 is particularly well suited to pharmaceutical research facilities, biotechnology companies, specialized biological research laboratories, vaccine-development facilities, and institutions requiring externally exhausted biological containment. It is also appropriate for laboratories replacing an existing Type B2 cabinet where the necessary facility exhaust infrastructure is already installed. Because the cabinet requires a dedicated external exhaust system, it is generally less suitable for laboratories without appropriate building ventilation capabilities.
