A high-pressure paint sprayer is an air-powered device that sprays paint at a higher velocity than a low-pressure paint sprayer. This type of paint sprayer has two types of air nozzles: one for fine misting, and the other for spraying thick layers. A low-pressure paint sprayer is an air-powered device that sprays paint at a lower velocity than a high-pressure paint sprayer. This type of spray gun is mostly used for painting furniture and other objects that are not flat or vertical.
