For saving energy, in a ventilation for a spraying booth, the high air-throughput rate necessary for carrying away the spray mist etc. is only maintained during the actual spraying operation. When the sprayer hangs the spray gun (31) on a hook (33), the power of the fan (18) is reduced to a fraction, for example 1/3, which is sufficient during these work breaks. <IMAGE> |
