Furthermore at least an outer boundary wall consists of noise-damping material. The arrangement includes modular units having several annular channels of which the boundary walls decrease in height from the outside to the inside. Each unit has at least one filter which is arranged in a region below the flow chamber. Innermost boundary walls with inner sides thereof adjoin a plate consisting of noise-damping material. The boundary walls are secured, hanging or suspended on the cover sealing part. At least one heat exchanger lies in a suction region of the ventilator via which the return air flows.
