EN Positive pressure ventilators are exposed to self-shifting during their operation. The aim of the article was to perform research analysing dynamic excitations resulting from vibrations caused by the operation of the drive system. The tests included four different fans, including one with an electric drive. The tests carried out made it possible to determine the effective RMS R value of vibrations, which is a maximum of 0.970 G, and the direction of the excitation relative to the vertical and horizontal axes. In addition, the values of vibration amplitudes on individual axes of the adopted reference system were determined. In this case, the highest values were measured on the vertical axes for combustion-powered ventilators (vibration value from 20 to 35 m/s2 ) and in the axis along the fan rotor for electric-powered ventilators (vibration value from 1.1 m/s2).
