ABSTRACT:
By making a mounting frame for a filter disposed at the front of the ceiling in a clean room of a sintered metallic material, the mounting frame obtains a structure with a strength capable of supporting the filter and with an air filtering resistance comparable to that of the filter, thereby preventing standing air in the lower part of the mounting frame and solving the problem of lowered purity of air.
