Analysis of roof cooling fans function in several working regimes is presented. The main goal of the research was to define the influence of fan working regime on airborn dust particles concentration. Dust concentration is significant microclimate parameter in the livestock building. Increased dust concentration affects the animal and workers health. During the different fan speeds, the measurements were conducted in characteristic building sections. There were 48 measuring points selected, in 4 hight levels, which totally covered the room. Comparative analysis of air flow velocities and dust concentrations showed that this fan setup may give satisfactory results. Certain working regimes were recommended for use, and the third speed step was emphasized.
