Mounting walls for walls with filters, esp. for central air conditioning/ventilation plant consists of connected trough-shaped segments with sets of holders for mounting of frames without tools

摘要

The mounting wall consists of a number of connected mounting segments (S1,S2), each of which is shaped like a long rectangular trough with continuous profiled esp. square openings (3) in the top. The trough has a C-shaped cross section. Sets (7) of flat mounting holders with arms are positioned pref. in pairs, between the openings, for mounting of the frames with filters without the use of tools. The walls (4) of each segment have compressed stiffening sections (5). The holders are fitted elastically, turnable, and sliding on bolts inside helical springs.
