Rotary Air Compressor Guide

Screw Air Compressor Air Dryer


Are you planning to buy a rotary air compressor for sale?

Well, you should proceed to do so.

However, before buying one, you must be well guided about this device.

Since information is power, having the right data about a rotary air compressor will help you choose the right one for your application.

Rotary air compressors come in different specifications.

Or, which compressor should I buy?

If you want to make the right decision, read on as we guide you on how to buy the best rotary air compressor for sale.

What is a Rotary Air Compressor?

A rotary air compressor is a type of air compressor that uses two asymmetric rotors to compress the air.

The rotors for this type of air compressor have a unique shape, and they tend to turn towards opposite directions hence leaving a minimal clearance between them.

These rotors are covered by two-shaft jackets that provide a cooling effect.

Take note that rotary compressors are very different from the reciprocating compressors.

The main difference is rotary compressors do not use valves to control the movement of air.

They are also lighter and have minimal vibration.

In terms of size, rotary air compressors come in different sizes.

You can choose to buy a small rotary air compressor or go for a large depending on your needs and application area.

Do I Need a Rotary Air Compressor?

Who should buy a rotary air compressor? Am I the right person to buy this device?

These are just some of the questions that you may be asking yourself about a rotary air compressor.

There are several criteria that you can use to gauge whether you are the right person to buy a rotary air compressor.

You should buy a rotary air compressor if:

  • You have either a large or a small production facility or factory. The compressor can be used for either application.
  • You have a big garage or workshop
  • You need large volumes of compressed air
  • You need compressed air on a continuous basis
  • You are tired of the reciprocating air compressor, so you want to replace it If you fit in any of the above conditions, then know that you are an ideal buyer for the rotary air compressor.

Components of a Rotary Air Compressor

Rotary Air Compressor Extras/ Accessories

Although there are essential parts of a rotary air compressor, you may wish to add extras.

Some rotary air compressor manufacturers even opt to sell the compressors with pre-installed extras.

The primary purpose of these accessories is to improve the efficiency and overall performance of a rotary air compressor.

1. Rotary air compressor with dryer

Naturally, compressed air tends to be wet. A rotary air compressor is integrated with the dryer so that this air is dried.

Wet air tends to have deposits of oil, which can cause mechanical damage to the machine. This means that compressor with dryer is likely to last for a long time.

2. Rotary air compressor with condensate traps

Although it is not a very vital accessory, you may still need it for the exemplary performance of the rotary air compressor.

The condensate trap also filters out the condensed moisture from the compressed air. This also protects other components of the compressor.

3. Variable speed drive

This is another rotary air compressor accessory that you may consider buying later on. The work of a VSD is to increase the speed of the rotary air compressor when necessary.

This is vital as it will help you to cut down on the cost of electrical energy that is consumed by the compressor.

4. Aftercoolers

Most large or stationary rotary air compressors are equipped with aftercoolers. Without this accessory the compressor will be pumping out extremely hot air.

Aftercoolers also filter out quite a significant amount of water from the rotary air compressor. Otherwise, this water vapor will find its way into other components.

Rotary Air Compressor Pressure vs. Capacity

2 stage screw air compressor

When it comes to choosing a rotary air compressor for whichever application, there are two main parameters that you will look at.

These are pressure vs. capacity ( air compressor PSI vs. CFM).

These two determine the overall performance of the air compressor.

How can I differentiate between these two?

First, it is important to know that an ordinary rotary air compressor is capable of operating 24/7.

When buying the compressor for the first time, you should check the specification details so as to know the pressure at which it operates.

From this information, you will be able to tell the volume of air that the compressor needs.

Find out the average and the peak consumption of the rotary air compressor.

If you are buying a rotary air compressor to replace your used rotary air compressor, ensure that they are of the same pressure and air capacity.

Before you choose to upgrade your compressor to a bigger rotary air compressor, think about the implication that it will have on your business.

Rotary Air Compressor vs. Reciprocating Air Compressor: Which One Should I Choose?

When it comes to buying air compressors, you may find yourself torn between two main types of compressors.

These are rotary air compressors vs. reciprocating air compressors.

Which one should I choose and why?

To get the best answer, lets look at the key performance areas in both.

-Performance: Which one is faster between rotary air compressor vs. reciprocating compressor?

In terms of performance, a rotary air compressor performs better than the reciprocating compressor.

This simply means that it delivers more volume of air per cycle as compared to the reciprocating compressor.

On the other hand, the volume of air that is delivered by reciprocating air per cycle is quite lower than that of the rotary air compressor.

Air pulse

Rotary air compressors are known for pumping air smoothly and continuously. In other words, they don’t have pulses.

On the other hand, reciprocating air compressors tend to have pulses. This is whereby air is pumped in spurts. To minimize this problem, modern reciprocating air compressors have reservoir tanks for the storage of pumped air.

Duty Cycle

What is the duty cycle of a rotary air compressor?

When it comes to air compressors, a duty cycle is the time frame in which an air compressor can operate continuously without stopping due to overheating.

If a compressor does so, it is said to have achieved a 100% duty cycle.

For instance, if a compressor can run for 70 minutes and you wanted it to run for those minutes, it is said to have 100%.

However, if it runs for 35 minutes out of the expected 70, it is said to have achieved a 50% duty cycle.

A rotary air compressor is designed to have a 100% duty cycle. It will continue to pump air without stopping.

On the other hand, reciprocating air compressors have a 50% duty cycle.


Which one is durable between rotary air vs. reciprocating air compressor?

A rotary air compressor has an ergonomic design with minimal moving parts. It also has compressor oil seals, which prevent the parts from wearing out.

For this reason, this reason, a rotary air compressor is likely to last for long.

Reciprocating air compressors have piston rings and other components that are always hitting against each other.

The components of this compressor wear out at a fast rate; hence it is not durable.


The Rotary air compressors are lighter than the reciprocating air compressors. This is because they have fewer moving parts.

This explains why you can easily buy a portable rotary air compressor and go to use it in whichever area of application that you want.

Do Rotary Air Compressors Consume High Amount Of Energy?

Are you concerned about the price of a rotary air compressor? Then you better rethink your choices.


The price will only take 10% of the rotary air compressor. At least 75% of the cost will go towards the cost of energy.

This is just to imply that rotary air compressors consume a significant percentage of energy.

So, what should I do to cut down on the energy consumption of the rotary air compressor?

The best thing to do is to check the energy rating of the compressor at the point of purchase.

Strive as much as possible to buy the best energy-efficient rotary air compressors.

Otherwise, you may end up incurring high cost to keep the compressor running. As a business, this will have a direct impact on your profit margin.
