Theoretical research indicates that, with all variables controlled, Class II biosafety cabinets (BSCs) with brushless direct current (BLDC) motors can save up to 80% in energy costs over conventional cabinets with alternating current (AC) motors. To validate this theory, the University of Michigan (Ann Arbor) conducted a field study on three brands of biosafety cabinets. The study showed that the BLDC cabinets can save significant amounts of energy over conventionally powered units and that this benefit is realized over a wide range of filter loading conditions. Therefore, the energy savings available from BLDC Class II biosafety cabinets warrant earnest consideration before purchasing AC motor Class II biosafety cabinets.
