In this paper mechanical system containing four horizontal blowers with separate frame each is analyzed. The system is fixed on one general foundation. The high level of vibrations is dominating during the work of the system. The results of experimental investigation of mechanical system are represented here. The finite element model of the operation investigated system gives possibility to investigate natural frequencies. The reasons of high level vibrations were identified by comparing the results of experimental data and theoretical calculations. The concept of vibrations reduction based on the results of this investigation was proposed as well.
