Abstract

A Coanda injector is provided, and has an inlet for a medium that is to be suctioned in. A pre-chamber having at least one inlet for receiving pressurized medium for a compressed gas line is provided, and has a nozzle slot that is preferably annular in shape. An outlet is also provided for the medium to be suctioned in and for the pressurized medium. The inlet for medium to be suctioned in, and the at least one inlet of the pre-chamber, are essentially disposed in the same plane, so that the Coanda injector can be connected directly to a compressed gas line via the at least one inlet of the pre-chamber.
