A heated paint drying system for drying paint on a vehicle using heated pressurized air includes an air supply supplying pressurized air. An air hose is coupled to the air supply and transfers pressurized air from the air supply. A housing includes a handle section, a head section, and a channel extending through the housing from the head section to the handle section. The air hose is in fluid communication with the channel when the air hose is coupled to the housing. A valve is positioned within the channel and a trigger selectively opens or closes the valve. A heat emitter is attached to the housing and heats pressurized air passing through the channel. An electricity generator is electrically connected to the heat emitter. The electricity generator has a driver manipulated by the flow of pressurized air, wherein the heat emitter is turned on when the driver is manipulated.

A dry space creation apparatus includes a processing tank, expansion members, an ejection unit, a dry gas supplier, and a controller. The processing tank has an internal space. The expansion members are provided in the processing tank and expand while leaving part of the internal space. The ejection unit ejects gas in the internal space out of the processing tank. The dry gas supplier supplies dry gas to the internal space. The controller performs first control to allow the ejection unit to eject the gas in the internal space out of the processing tank with the expansion members expanding, and then performs second control to allow the dry gas supplier to supply the dry gas to the internal space with the expansion members contracting.
