Electrostatic spray apparatus for applying a liquid coating material to a workpiece, comprising: a rotatable bell-like atomizer head for receiving and centrifugally atomizing liquid coating material and propelling the same as a cloud towards the workpiece; first means defining a first annular gap coaxial about said atomizer head for connection to a compressed air supply for controlling the outer limits of the cloud; and second means defining a second annular gap coaxial about said first annular gap for connection to a compressed air supply for returning to the cloud those particles of the liquid coating material which erupt out of the cloud, each of said first and second means comprising a first element including a first section limiting the respective air gap, and a second ring element mounted on and coaxially movable with respect to said first element and including a second section limiting the respective air gap.
