A working environment room comprises at least four substantially elongate, vertical legs (10, 20, 30, 40) which have a lower end and an upper end, and a ceiling (91) which is joined to the legs (10, 20, 30, 40) at the upper end of the respective legs and which interconnects the legs. Each of the legs (10, 20, 30, 40) supports fan means (12, 22, 32, 42) which are adapted to be driven in at least two operating modes, each fan means being adapted to supply air to the room in a first operating mode and to exhaust air from the room in a second operating mode, and each fan means (12, 22, 32, 42) being individually controllable between said two operating modes for adjustment of the air change of the working environment room. |
