Types of Air Compressors

The most common types of compressors are screw, piston, axial and centrifugal compressors. The air compressor is one of the most commonly found equipment on construction sites and factories, as it can be used as a power source for a variety of electrical equipment. There are several types of air compressors, each with their own advantages and disadvantages. If you need an air compressor, you need to know the difference between each type of the best air compressor for your home garage.

Based on its internal mechanism, air compressors are categorized as positive displacement and dynamic displacement. The four most common types of air compressors are:

Screw Compressor (Rotary Screw Compressor)
Piston Compressor (Reciprocating Compressor)
Axial Compressor (Axial Compressor)
Centrifugal Compressor

Air compressors fall into two categories: positive displacement and dynamic displacement

Positive Displacement Compressor Type
Positive displacement compressors include a variety of different air compressors that generate power through air displacement. Air compressors in this category work by a different internal mechanism, but the principle of action is the same. A cavity in the engine stores air that is brought in from the outside, and then slowly presses against the cavity to increase the air pressure and potential energy.

Dynamic Displacement Compressor Type
Dynamic air compressors generate power by carrying air with fast rotating blades and then confining the air to create pressure. The kinetic energy is then stored as static in the compressor.

Apart from the power generation mechanism and energy output rates discussed above, there are several other factors to consider when choosing the right type of air compressor. In a clean manufacturing environment, air compressors with oil can cause problems. Most air compressors rely on oil to lubricate the internal mechanisms and fumes from the compressor can contaminate the air. Sometimes, this smoke can cause damage to the product or manufacturing process at the factory. In this case, you will need an oilless (oil-free) air compressor. Although oil-free compressors are generally more expensive, they are the only option for a facility that guarantees a clean manufacturing process.
