When choosing a paint spray gun, several factors should be considered.

Types of products to be sprayed
Firstly, the choice of paint spray gun should be based on the type of product to be sprayed.
Used for selecting air paint spray guns for varnish and wood coloring agents, specifically designed for spraying thin and bright products. This spray gun is particularly suitable for the automotive industry.
For traditional paints, acrylic or latex paints, as well as thick and viscous products such as coatings or adhesives, you can choose any airless spray gun

High pressure or low pressure?
The pressure required for a paint gun depends on the type of work you plan to perform.
Suitable for one-time operations on small surfaces, low-pressure spray guns are the best. HLVP spray gun is recommended for small surfaces and is an ideal choice for woodworking and cabinet manufacturers.
If you want to spray paint on a large surface, you can choose a high-pressure spray gun

Flow rate: To apply paint or varnish to furniture, low flow rate is required. On the other hand, for example, to repaint the exterior walls of a building, a large flow rate is required. Some models of paint spray guns have an adjustable flow rate. It is not recommended to use spray guns with non adjustable flow rates as they have poor versatility and cannot be used for various tasks that require different flow rates.

Size of paint storage bucket: For spray guns with paint storage buckets or cups, the size of the paint storage bucket is a necessary factor to consider. A larger cup can hold more paint and take longer to apply. However, the spray gun will also be heavier and more tiring to use.

Nozzle: A nozzle is a component in a spray gun that sprays paint (or other products). The nozzle is easy to replace because it needs to be compatible with the sprayed product (viscosity, etc.). Horizontal spray nozzles or fan-shaped nozzles can be fixed or adjustable. It is recommended to use adjustable nozzles as they can change the spraying direction.
