ABSTRACT:
A combination of two frames (2) and (4), one inside the other, for positioning a filtering ceiling. The frames have indented splines (3) and (5) on their facing surfaces, and an inflatable tube (6) is anchored on the spline of one of the frames. The tube is inflated to properly position the two frames, to hold the ceiling in place and to seal it so that all air must pass through the filtering ceiling. The tube is deflated to allow the filtering ceiling to be lowered for maintenance or replacement.
