Types of Air Compressors

air compressors

There are several types of air compressors, from Oil-injected screw compressors to Reciprocating, Positive displacement and Oil-free. Before choosing the best type of air compressor for your needs, it is important to know what you’re looking for. Here are some basic differences between each type. Also, make sure to learn more about the benefits of each type. Then, start shopping for an air compressor today! Here are some basic tips to choose the best air compressor for your needs.

Oil-injected screw compressors

There are two types of screw compressors: oil-injected and oil-free. Oil-injected screw compressors have the advantage of near-isothermal compression, meaning that any heat generated during the compression process is almost absorbed by the oil. The temperature of oil injected into the compression chamber is typically between 60 and 700C, while the discharge temperature should be above the pressure dew point. An oil cooler controls the amount of oil being injected into the compressor, and an air aftercooler is used to cool the discharged air and remove excess moisture.

Positive displacement

Positive displacement air compressors are high-level compression devices that draw ambient air into the chamber and squeeze it into a smaller volume. The compressed air then exits the compressor’s outlet system. There are two basic styles of positive displacement air compressors, the rotary style and the reciprocating style. This article discusses the differences between them. Read on to learn more about both types of compressors. And what makes them different from each other!


Reciprocating air compressors use both sidesĀ pacificaircompressors of a piston for compression and suction. The pressure inside the cylinder gradually drops as the piston moves up and the pressure in the cylinder on the top side increases. Ultimately, this causes a pressure difference across the inlet and discharge valves to overcome a spring force. This process allows the compressor to compress and unload air twice as fast as a single-acting model.


Oil-free air compressors are a viable solution to your air purity requirements. With their smaller size and equal air pressure, these machines are perfect for the manufacturing industries. As these air compressors are less costly to maintain, they are favored by many industries. In addition to these benefits, oil-free air compressors are becoming increasingly popular as regulations related to hygiene and safety in food and beverage manufacturing are tightening. Oil-free air compressors are lighter and more compact than ever before, which means they will reduce your costs and help you improve your bottom line.


Air compressors are indispensable equipment that compresses and pressurizes air for a variety of uses. They are indispensable for pneumatic operations in industrial facilities, factories, and workshops. Compared to pumps, they are relatively newer. They can be used for a wide range of tasks, including powering compressors for air tools, welding equipment, and impact wrenches. Some compressors even have the capability to power concrete compactors and jackhammers.
