Abstract (en)
[origin: DE19706144C1] A clean room air circulator assembly suspended from the ceiling has a housing (10) wall (13) with a ventilator inlet (16) and a filter (19) discharging air to the room. The novelty is that: (a) the housing wall (13) is formed of a number of bow-shaped parts bending towards the outlet side; and (b) the two rims of the housing wall (13) are fold-joined (14, 15) to parallel side-walls (11, 12); (c) those sections of the rims (13) and side-walls which are not fold-joined (14, 15) form the limits of the blower outlets.
