ABSTRACT:
Contaminated air is drawn from a relatively enclosed dirty air space and filtered to remove both contaminants and other particulate materials. A main mechanical filter is positioned between the dirty air space and a surrounding environment which is to be protected from contamination. An exhaust fan is positioned on the output side of the main filter, to create a partial vacuum within the dirty air space. An irradiation device is positioned on the output side of the main filter. A secondary vacuum system is utilized to create a secondary vacuum that is substantially stronger than the partial vacuum applied to the main filter, and the secondary vacuum is applied to successive selected portions of the air input side of the main filter for creating a reverse air flow to clean contaminants and other particulate materials which are being continuously deposited there. Within the secondary vacuum system air is circulated through at least one filter element that is located remotely to the dirty air space, and the thus filtered air is then dumped back into the air input side of the main filter. Accumulated particulate material is removed from the remote filter from time to time, without entering the dirty air space itself.
