What are the main parts of a paint spray gun?

The primary components of a paint spray gun include the trigger, fluid nozzle, and air cap. The trigger is essential for controlling the flow of paint; when pulled, it opens the valve to release the paint. The fluid nozzle is responsible for atomizing the paint, breaking it into fine particles for an even spray application. The air cap directs the air flow that assists in atomization, helping to create a fine mist that allows for smooth and even coverage on a surface. Understanding these components is crucial for anyone working with spray guns, as they directly influence the quality of the paint application and the overall finish of the repair work.
