The invention relates to a unilaterally open clean-room cabin 1, formed by two side walls 7, 8, a rear wall 2, a roof and a floor, for production or filling devices, in particular for foodstuff filling or the like, with a ventilation installation for achieving an extensively particle-free atmosphere in the region of the production and filling device 13 with the aid of a low-turbulence displacement flow. To form a horizontal low-turbulence displacement flow, the rear wall 2 of the clean-room cabin 1 lying opposite the cabin opening 6 is designed to be dimensionally stable over its entire surface as incoming-air outlet and the cabin opening 6 as outgoing-air opening for the outlet of the air supplied to the clean-room cabin 1 into the surrounding space 21 of the clean-room cabin 1. The side walls 7, 8 and the roof are designed to be dimensionally stable. Provided on one cabin wall is an air suction device which is connected to the surrounding space 21 of the clean-room cabin 1. The rear wall 2 consists of a suspended-matter filter 3 extending over the rear wall surface, a prefilter 5 arranged at a distance therefrom and, between suspended-matter filter 3 and prefilter 5, fans 4, by means of which incoming air is drawn in from the surrounding space 21 and introduced into the clean-room cabin 1. <IMAGE>
