    摘要: An air cleaning apparatus such as a clean room or the like having an air circulation mechanism which circulates the humidity controlled air through a predetermined air circulation path, wherein the air circulation path is provided with a filter which has a hydrophobic zeolite layer formed on its base filter media surface and another filter which is disposed downstream from the filter having a hydrophobic zeolite layer and is used for removing particulate impurities contained in the circulating air. According to this air cleaning apparatus, gaseous organic impurities and particulate impurities contained in the air circulating in the air cleaning apparatus can be removed without lowering the humidity of the circulating air. Furthermore, since this air cleaning apparatus includes no activated charcoal which is inflammable, the apparatus is excellent from the standpoint of disaster prevention. Accordingly, the filters according to the invention and particle filters can be installed with safety in the ceiling portion of the air cleaning apparatus.

    摘要: An apparatus for removing static electricity from charged articles existing in a clean space, particularly in a clean room for the production of semiconductor articles, includes a AC ionizer having a plurality of needle-like emitters disposed in a flow of clean air. A discharge end of each emitter is coated with a dielectric ceramic material. Opposite conductors are also included which are respectively positioned apart from the discharge end of each emitter by a predetermined distance. Each opposite conductor is grounded. Emitters of some of the discharge pairs are connected to a high voltage AC source having added thereto negative voltage bias to thereby form pseudo negative pole emitters, and emitters of the other discharge pairs are connected to a high voltage AC source having added thereto a more positive voltage bias relative to the negative voltage bias to thereby form pseudo positive pole emitters.
