4. Centrifugal Air Compressors

This compressor equips an impeller that is mounted on the shaft and placed within the housing. The other aspects it includes are a diffuser, volute, and an inlet duct. When the impeller rotates at a high speed, the air is imparted. The impeller is surrounded by the diffuser and functions like a converter to generate air in the form of potential energy at a great pressure level.

5. Dynamic Type Air Compressors

Such compressors pass velocity to the air using mechanical friction. It is produced by the rotating impellers in the casing at great speed. Air is placed into the cylinder at high volume, which eventually reduces balancing the pressure. The volume flow may alter as per distinct pressure in the compressor.

6. Rotary Air Compressors

Within this compressor, the air is compressed by two interconnected or rotating rotors. It is further divided into distinct categories on the basis of its engineering as Rotary Vane and Rotary Screw compressor.

Rotary Vane – It comes with a movable rotor blade and compresses air between the casing and rotating rotors. These air compressors can be double stage and single stage.

Rotary Screw – It comes with two rotating female and male screws and compresses air using them. When air is compressed, it reduces the space between them gradually resulting in suitable pressure to work seamlessly.

7. Reciprocating air compressors

This compressor produces air with the piston’s movement within the compression chamber. Whenever the piston moves, the air is compressed at a fixed amount at a specific pressure. It comes in distinct types like multi-stage, single-stage, double acting and single acting compressor.

It comes in horizontal and vertical form and ranges in the air at 50 to 150 ranges. The other uses compressed air at the range of 200 to 5000 CFM.

How Do Air Compressors For Spray Painting Work?

A motor is integrated within the air compressor using which the steel tank is filled with huge air volume. When more air is pumped inside the air tank, it gets compressed and pushes together.

A pressure chamber is created in the vessel, which gets higher over time. A bigger tank size means more air, and hence, more pressure on the compressor.

When this compressed air is available for use, it is pumped out through the air hose to offer air pressure to the numerous power tools you want to use.

If you use this compressor for spraying paint, it drives air through the air hose into the spray gun and creates an air flow, which draws paint into the path due to low pressure. It generates a paint aerosol and lets you spray the pain on the surface for completing the painting job.

When the air compressor runs down, you need to turn the unit back to building up pressure again to supply power to the tool.

 How You Can Easily Pick The Best Air Compressor For Spray Painting?
