Types of Paint Spray Guns

Paint spray guns are categorized into different types based on their functionality, design, and application.

The weight and ergonomics of a paint spray gun can also affect the overall safety of the painting process. A gun that is too heavy or uncomfortable to hold can lead to accidents and injuries, such as slipping or falling. It is also important to consider the balance of the gun, as this can affect the overall stability and control. A paint spray gun with a comfortable grip and balanced design can reduce the risk of accidents and make the painting process more enjoyable.
