The NU-560 combines durable construction and an efficient motor with a control system providing the safety and monitoring appropriate for the demanding work done in a Class II Type B2 biological safety cabinet. Overview The NU-560 biological safety cabinet uses a DC ECM motor that economizes energy while evenly distributing laminar downflow air through a flexible plenum and retaining enough power to overcome supply HEPA filter loading and minimize filter changes. This cabinet’s construction provides the user with a work zone whose side and back walls are constructed from a single piece of stainless steel for enhanced containment and easy cleanability. The LED bulbs efficiently illuminate the procedure inside while a single-piece dished work tray traps most spills above it but includes a prop rod to allow cleaning underneath. An outlet is placed on the left front faring and a cord-pass through is built into the right sidewall for the user’s convenience. The exhaust is powered by an external facility blower that is interlocked with the cabinet’s own motor through a redundant system to provide two layers of protection that minimize the risk of blowing air out of the cabinet should the external blower fail: cabinet exhaust is monitored by not only a mechanical pressure switch but also a differential velocity pressure flow grid. A touch screen displays the readings from both this flow grid and a down flow sensor in the work zone at all times for the cabinet operator. Models are available that meet the commonly respected NSF/ANSI 49 standard for biosafety cabinets.
