ABSTRACT:
An auxiliary device is used in the exchanging of a filter in a clean room having a production section, and a filter frame including a filter-supporting portion which supports the filter and an extending portion which extends from the filter-supporting portion toward the production section. The auxiliary device includes a block plate to be inserted in the extending portion of the filter frame, a support supporting the bottom of the block plate and facing an inside wall of the second portion of the filter frame, and an inflatable tube disposed along the circumference of the support. The tube is inflated to press outwardly and seal the device in the filter frame, thereby blocking the flow of any unfiltered air past the filter and into the production section. Thereafter, the filter is removed and a new filter is set in its place. Finally, the tube is deflated so as to free the device from the filter frame. Accordingly, the production operation as well as the circulation of cleaning air can proceed while the filter is being exchanged.
