Abstract: The present invention relates to a rotary atomizer for coating products comprising a main body and a bowl rotated by a rotating member about a axis of rotation defined by the main body. The bowl is equipped with first means of magnetic coupling apt to cooperate with matching second means of magnetic coupling fastened to a non-rotating part of the atomizer. The first and second means of coupling are apt to exert a force at least partially axial with respect to the axis of rotation of the bowl, the force inducing the coupling in rotation of the bowl with the rotating member. The second means of magnetic coupling are supported by an air supply skirt directly mounted on the main body.
