The module has a side wall construction formed by side plates (4) which are supported in a sealed manner by the frame-shaped beam construction running crossways towards the filter and around its periphery. A cover plate (6) is connected to the upper edges of the side plates and contains an air entry aperture (12). Between the cover plate and the filter is a fan (10), which blows air towards the filter (8) coming in through the air entry aperture. The cover plate supports an accessible, dismantlable panel (20). The fan is upwardly dismantably supported under the cover plate and the air entry aperture is sufficiently large to permit passage of the fan for installation or dismantling purposes. A lifting and support device (58) for the fan is formed as a link arrangement preventing eddy formation and located above the fan inlet. |
