A New Principle for Airborne Contamination Control in Clean Rooms and Work Stations


A description is given of a new principle of closely controlling airborne contaminants in clean rooms and work stations that provides two basic improvements over the conventional principle. First, the system of air-flow patterns and filtration provides and maintains airborne contamination levels of less than 1000 particles per cu ft, 0.32 μ and larger. This level is attainable in both clean rooms and open-front work stations. Secondly, about 90 per cent of personnel restrictions required by conventional clean rooms are eliminated. Clean-room clothing is not needed; and, in most installations, air showers and entry ways also are not needed. Data about two clean rooms and a work station are presented, all of which are based on a new principle for airborne contamination control.
