Basic Information You Need Before Ordering a Rotary Screw Compressor

Rotary screw compressors are very commonly used in a wide variety of different industrial applications. An air compressor is a device that compresses and stores air in a tank for use later on. When released, the gravitational potential energy of the air turns into kinetic energy, which is required for an extensive range of different applications. Now, rotary screw compressors are just one of the many different kinds of compressors available today so you have to be a bit careful when buying one. If this is the first time that you are ordering a rotary screw compressor, here is some basic information that you should keep in mind.

How Does it Work?

Rotary screw compressors displace gas using a positive displacement mechanism and are commonly used instead of piston compressors. Rotary screw compressors are generally used in applications where large amounts of air circulation are needed.

They are available for use in industrial applications as well as in portable devices such as jackhammers. It uses a continuous sweeping motion for compressing the air, which prevents excessive surging of flow or the pulsation that is common in piston compressors. There are two helical mesh screws, called rotors, that are used to drive the compression mechanism forward. You can either choose between a lubricated air compressor or a dry rotary compressor depending upon your requirements.

Whereas dry air compressors require a bit more maintenance, they are suitable for specific industrial applications. Most of the rotary screw compressors are usually quite compact in size, run very smoothly, and create virtually little to no vibration whatsoever. As a result, you don’t have to fix it on a spring suspension or a rubber suspension as is the case with most common compressors. Now, if you are looking to order rotary screw compressors in Melbourne, you need to do a bit of research before placing an order. Here are a few tips before ordering a dry air compressor.


The first and most important thing that you need to focus on is the price of the rotary screw compressor. Different compressors are available at different prices so you will first need to make a shortlist of different companies that offer industrial rotary screw compressors. Once you have made a shortlist, you can then request quotes from different companies and compare the prices.

The prices generally vary depending upon the size of the compressor or the industrial application for which it is required. Custom rotary compressors are designed for certain applications so you have to first request a quote from an engineer. The installation of a rotary screw compressor is also a pretty sensitive task so you will need to call in a certified professional for installing it. Once the rotary screw compressor has been installed in place, the engineers will show you all of the installed features and give you the maintenance schedule. Timely maintenance is necessary from time to time to ensure that the compressor continues to run smoothly.
