  • Clean room system
    Patent number: 4676144
    Abstract: A clean room system includes a processing room containing production equipment, a technical room adjacent the processing room and containing machinery for actuating the production equipment, and a wall separating the production equipment from the actuating machinery. The wall also serves to isolate the atmosphere of the processing room from the atmosphere of the technical room and to prevent contaminants emitted by the machinery from entering the processing room and, ultimately, contaminating the goods being manufactured or processed. The clean room system also is provided with a ventilation system for recirculating and filtering the atmosphere of the processing room. The ventilation system maintains the atmosphere of the processing room at a higher pressure than that of the atmosphere of the technical room to prevent air from passing from the technical room into the processing room.
