According to the feeding method, the air duster gun can be divided into three types: pressure type, siphon type, and gravity type. Let's take a look at the working principle and main features of these three air spray guns.

The pressure spray gun delivers the paint to the spray gun through the pressure of a pressure tank or double diaphragm pump. The spray gun itself does not have a tank, which reduces the weight of the spray gun and reduces the labor intensity of the operation. It is especially suitable for continuous surface and discontinuous operation, preventing the stoppage caused by feeding and improving the work efficiency to achieve the best spray quality.

The lower part of the siphon spray gun is equipped with a paint tank. The compressed air generates a low-pressure vacuum in the front half of the spray gun. The atmospheric pressure sucks the paint from the paint tank to the spray gun. The paint tank is divided into 600ml and 1000ml. optional. The spray gun can work with compressed air, no other equipment is required. However, it can only be operated on a normal level, and the inclination of the spray gun is limited. The siphon type is suitable for all kinds of coatings.

The upper part of the gravity spray gun is equipped with a paint tank, and the paint is delivered to the spray gun by gravity. According to the position of the paint tank relative to the axis of the spray gun, it can be divided into side type and central type. During operation, the central version limits the tilt of the spray gun, while the side version allows the operator to stop spraying in different positions, while the paint tank remains vertical. The disadvantage of the side type is that the size of the paint can is small, usually 400ml, and the consumption efficiency is low. But the biggest advantage of gravity is that there is very little waste of paint. It is easy to clean and consumes less solvent.
