Abstract: A ceiling-mounted air-treatment unit is described. The unit includes an inlet air duct arranged to receive an inflowing air stream, a ceiling mounted plasma reactor for filtering and biologically decontaminating the air stream as it passes through the reactor, and an outlet duct for discharging treated air into a room requiring a sterile environment. The plasma reactor includes a plasma generator, an electrostatic filter, and optionally a catalyst to remove reactive species from the treated airflow. Additionally, the plasma reactor is arranged in a ceiling mounted frame that arranges the plasma reactor in an operating position in the ceiling and is movable to a service position where the plasma reactor can be moved downward into the sterile room for maintenance and servicing.

Abstract: A variety of transportable air treatment system improvements are described. In one aspect of the invention, the system is designed to significantly reduce the noise generated during operation. In another aspect, an easily removable cooling unit is provided. In still another aspect, an air treatment unit (as for example a plasma reactor) is provided that is arranged to filter the air stream, inactivate biological organisms and/or reduce or eliminate volatile organic compounds (VOCs) that are carried in the air stream. The air treatment unit may take the form of a plurality of stacked trays. In yet another aspect of the invention, the air treatment system further includes a duct unit that directs air from the air treatment unit to the treated air outlet. The duct unit is operable to clamp the stacked trays to help seal the stacked trays.
