Abstract
A system, in certain embodiments, may include a spray coating device having a self-contained air system. The self-contained air system is adapted to supply a desired amount of air pressure within the spray coating device. Further, the self-contained air system comprises only an air blower rendering the spray coating device air tank-less.
Claims20
A system, comprising:
- a spray coating device, comprising:
- a spray gun comprising a spray head, a handle, a base enclosure coupled to the handle, and an air passage extending through the handle from the base enclosure to the spray head, wherein the handle is disposed between the spray head and the base enclosure;
- and
- an air flow generator disposed in the base enclosure, wherein the air flow generator comprises a battery, a motor driven by the battery, and a plurality of blades rotatable by the motor, wherein the plurality of blades is configured to force an air flow through the air passage.

A system, comprising:
- a spray gun, comprising:
- a body;
- a spray head coupled to the body, wherein the spray head comprises a liquid port and an air port;
- a handle coupled to the body, wherein the body is disposed between the spray head and the handle;
- a trigger coupled to the handle;
- a liquid valve coupled to the trigger, wherein the liquid valve is disposed along a liquid passage extending to the spray head;
- and
- a base enclosure coupled to the handle, wherein the handle is disposed between the body and the base enclosure, wherein the base enclosure comprises a battery, a motor driven by the battery, and a plurality of blades rotatable by the motor, wherein an air flow path extends from the base enclosure, through the handle, through the body, and into the spray head to the air port, wherein the plurality of blades is configured to force an air flow through the air flow path, wherein the trigger is coupled to a switch configured to enable and disable the motor.
