The Different Types Of Air Compressors

Air compressors are one of the most useful tools that you can invest in. It can do the simple task of inflating your balloons to more serious tasks such as fixing your refrigerator or automobile. They definitely have a wide range of uses and they come in different types as well. Here are the types of air compressors that you can find in air compressor rental services:

Rotary screw

The rotary screw air compressor fills air into a void that is between two mated screws. Once these screws are turned, the volume will reduce, causing an increase in air pressure. Most units require you to inject oil into the bearing and compression area for cooling and lubrication purposes.

Reciprocating or piston

This type of air compressors are the most common in the market. This type of air compressors pumps air in the air chamber, which reduces its volume. It works similarly to the way a combustion engine works. This positive displacement compressor can give you minimal to very high horsepower and have pistons, cylinders, valves, and crankshafts.

Rotary sliding vane

In this compressor, the pump comprises of eight blades, a stator, and a rotor. When the rotor revolves, compression takes place and the volume becomes maximum at the intake port and minimum at the exhaust port. Like the rotary screw, oil is also injected for lubricating and cooling purposes.


Unlike the above-mentioned types of air compressors, the centrifugal air compressor stands out because it is not a positive displacement compressor. It uses high-speed impellers that spin to accelerate the air. Then it uses a diffuser to decelerate the air.

If you find yourself renting the air compressor so much, why not save yourself from the hassle and just get your own? You do not have to shell out a huge amount of cash for a brand new air compressor. You can easily find used air compressors for sale locally or online.
