Abstract: An air brush includes a housing having a chamber. A battery-driven fan is rotatably disposed in the chamber. The fan includes a plurality of radially extending blades. The chamber has an inlet opening and an outlet opening. A paint container is associated with the inlet opening for supplying paint to the fan. In a preferred embodiment, a guide extends from the paint container into contact with the fan blades for guiding paint to be sprayed to the extremities of the fan blades. The outlet opening is restricted by a detachable cover having a hole therethrough. The hole is of a selected predetermined size and shape to help spray a predetermined area with the air brush. The cover may be removed to permit a broader spray discharge. The chamber in the housing is provided with a drain opening. A detachable reservoir is secured to the housing below the drain opening for collecting paint discharged from the drain opening.
