In this paper the mathematical modeling and the 3D simulation of a pneumatic levitator are presented. The forces generated by the system are explained, the characteristics of a real levitator are calculated through experiments and finally the result of the modeling system is verified by the simulator. The simulation results have led to the conclusion that this model behaves within the common parameters for this type of processes according to the fluids mechanics theory and the behavior of the real process created according to the design.
