How Does an Oil-Free Air Compressor Work?

How Does an Oil-Free Air Compressor Work?

The primary function of an air compressor is to capture and compress the air, thus converting power into potential energy stored in the pressurised air. Different types of air compressors use different kinds of methods for compressing the air and forcing it in a tank. As air fills up the tank, the tank pressure continues to rise. When the tank pressure reaches its maximum limit, the compressor automatically shuts off. The tank is used for storing the air until it actually needs to be used. The compressed air can be used for a variety of different purposes. The kinetic energy stored in the compressed air is generally used in various different industries.


Different types of compressors are used for different applications. The three most common types of compressors include rotary screw compressors, rotary centrifugal compressors, and reciprocating air compressors. Rotary screw compressors are used in several industries. However, they require regular maintenance. The internal screws need to be oiled on a regular basis to keep the compressor working normally.

Conventional compressors that require oil also contribute to air pollution. The risk of oil spills is also considerably high. As a result, many workers have begun switching over to oil free compressors in Melbourne. These air compressors are constructed with care and precision, and don’t require any sort of lubrication. The screws used in these compression systems are also contact-free, thus minimising the risks of breakdowns.


Oil-free air compressors are used quite commonly in a variety of industrial applications. Since they offer superior efficiency and safety as compared to lubricated air compressors, they have become pretty popular in factories and houses alike. One of the biggest benefits of using oil-free air compressors is that they compress air with the help of internal screws. This significantly reduces the discharge pressure when compared with other systems. Certain multistage oil-free compressors make use of numerous screws in order to achieve the maximum discharge pressure. They are able to cover more than 57 cubic metres in a minute.



One of the issues with conventional oil-free air compression systems is that they are not as durable as lubricated air compression systems. Since there’s no metal covering to protect the compressor when it gets knocked around, they are likely to break down quite often. That’s why oil-free compressors need to be tightly kept in firm positions when they are being used. Regular maintenance and proper care can increase the useful life of the compressor significantly.

The costs of oil-free air compressors generally begin from around $3,000 and can go as high as $10,000. It’s important to consider the power ratings of the compressor before making a purchase. Smaller compression systems generally use less power. The speed of the air compressor can be regulated and that will also have an impact on the power consumption. It’s always wise to compare the features provided by different compression systems before making a decision about which one to buy for personal use.
