(57) : The invention pertains to a filter retaining assembly which is rigid and self-supportive without requiring any additional structural rein- forcement. The design maximizes the filter surface to be used for air filtra- tion and increases the filtration efficiency. The invention is also designed to minimize the filter assembly size to fit into the valuable space when the air = _ = = = = 1. / handling unit physical dimension is constrained. The invention uses integral construction methods to save assembly time and labor by eliminating the need of using alignment holes and fastening each individual frame to con- struct a conventional filter retaining assembly. The proposed method main- = = _ _ = iiis 121 tains flexibility of scaling to any filter size and quantity. = 12 4 = _ = 1 _ — = CID — 1-1 .4 M 1 41 V; 11 M ei ei 102 IN Il FIG. 1 © ei O [Continued on next page] WO 2017/223163 Al MIDEDIMOHNIIMMEMEEHOIIIIMEMOMOVOIMIE Published: — with international search report (Art. 21(3))
