Abstract: An air brush is shown and described including a replaceable, rotatable, nozzle head including a media port and a needle arrangement. Media contamination of the air brush is limited to the removable nozzle head, thereby making the air brush body free of media contamination. By rotatable mounting of the nozzle head, a variety of media sources are made available, ranging from gravity fed devices such as media top and side cups to suction fed devices such as media jars. The trigger arrangement of the present invention presents an actuator shaft movable longitudinally in response to trigger movement for engagement of the needle of the nozzle head. Mechanical coupling between the air brush body and nozzle head is limited to structural coupling for mounting the nozzle head and an abutment relationship between the actuator shaft and the needle. This allows rotational freedom of movement for the nozzle head relative to the body, and also ease of dismounting by simply separating the nozzle head from the air brush body.
