An air amplifier is provided for use in pneumatic control systems that can operate over a wide range of flow and pressure characteristics, and can additionally operate against a back pressure. The air amplifier utilizes a tapered shim that causes the pressurized air to follow a Coanda profile over a wider range (and against a back pressure) than is possible when using only a slotted, non-tapered shim. The shim is ring-shaped with a planar surface and includes inwardly directed tangs that are cut-off to provide an open central area. Some or all of the tangs are tapered along either one or both sides of the tang.
