How Does a Paint Gun Work?
Major Parts of a Paint Gun Paint guns can either be gravity fed or suction fed, which refers to how paint gets from the reservoir into the main chamber of the gun. The reservoir is a simple plastic container that holds paint. On a gravity-fed gun, it will be on the top of the gun, inverted so that paint is naturally pulled down into the gun. On suction-fed guns, the reservoir is usually below the gun and relies on a small tube to siphon the paint upward. The other major parts of a paint gun are the air cap, which is the main chamber of the gun. The holes on the end of the air cap control the spray pattern of the gun. Inside the air cap is the fluid tip, which is an internal extension of the reservoir. It holds the fluid needle, which is connected to the trigger. As the trigger is pulled, the fluid needle retracts into the fluid tip, creating a space where paint can flow into the air cap and be ejected from the gun. How It Works Paint is normally a fluid, but paint guns convert paint in
