Equipment that combines a durable construction and an efficient motor with a control system that provides adequate monitoring for the safety of personnel, the product and the environment, under the demands of work carried out in a biological safety cabinet. It uses an energy-efficient DC-ECM motor while evenly distributing laminar downward flow air through a flexible chamber and retaining enough energy to overcome the loading of the supply HEPA filter and minimize filter changes. The side and rear walls are constructed from a single piece of stainless steel to improve containment and facilitate routine equipment cleaning. LED bulbs efficiently illuminate the procedure inside, while a one-piece concave work tray catches most spills, as well as includes a support rod to allow for cleaning underneath.
