What Are The Three Types Of Air Compressors?

Do you want an air compressor for your applications? That is the first step. The next step is to determine the compressor type suitable for your projects. Which air compressor type should you buy? That is a big question that requires a lot of consideration. To get you started, this post highlights various types of air compressors. 

What Are The 2 Types of Compressors?

Basically, all compressors are grouped into two broad categories. The two main types of compressors are dynamic and positive displacement

Positive Displacement compressors

Positive displacement compressors work by trapping a specified quantity of air in the compressor chamber. The volume of the trapped air reduces, resulting in pressure rise. The three most common types of positive displacement compressors are:

  • Reciprocating, piston air compressors
  • Rotary screw air compressors
  • Rotary vane air compressors

We will look into these compressor types later. 

Dynamic compressors 

Dynamic air compressors are commonly used in large manufacturing plants. These compressor types include:

  • Centrifugal air compressors
  • Axial flow compressors

These compressors are also discussed in this post. 

From the two common compressor categories, you can find other compressors types in the market. These three compressors discussed below are the most common compressors at the moment. 

What Are The 3 Types of Compressors?

Basically, there are three common compressor types in the market. These are:

  • Reciprocating air compressors
  • Rotary screw air compressors
  • Rotary vane air compressors

Each one of these compressor types has different applications, advantages, and disadvantages. Additionally, they are designed differently for their unique applications. Here is a breakdown of each compressor type.

Reciprocating compressors

Reciprocating compressors are very common in the market and are probably the most used compressor type. There are many reciprocating compressor manufacturers offering many options.

Advantages of reciprocating compressors

  • Reciprocating compressors are more cost-effective in terms of the initial purchase price. 
  • They are more suitable for low-duty cycle applications. 
  • Reciprocating compressors are low maintenance. 

Disadvantages of reciprocating compressors

  • Reciprocating compressors are heavy and bulky. 
  • They have many moving/rubbing parts.
  • Reciprocating air compressors require air receiver tanks, taking up more space. 

Rotary Screw Compressors 

Rotary screw air compressors were traditionally found in stationary applications. However, these compressors are now designed for use in various industries. 

Advantages of rotary screw air compressors

  • Rotary screw air compressors have a longer life cycle and high airflow delivery. 
  • They are suitable for high-duty cycle applications.
  • They do not require air receiver tanks.
  • They have fewer wearing parts. 
  • They are relatively low-cost in terms of maintenance. 

Disadvantages of rotary screw air compressors

  • Rotary screw air compressors are expensive. 
  • Rotary screw air compressors have independent lubrication circuits. 
  • They require routine maintenance. 

Rotary Vane Compressors 

Rotary vane air compressors are the least common compressor types. There are fewer rotary vane compressor manufacturers compared to other compressor types in the market. 

Advantages of rotary vane air compressors 

  • Rotary vane compressors have fewer wearing parts. 
  • They are more compact. 
  • They deliver relatively pulsation-free air flow. 
  • They are more affordable. 

Disadvantages of rotary vane air compressors

  • The more they operate, the more the oil carry-over increases. 
  • Servicing a rotary vane compressor can be very expensive. 
  • It is challenging to find service parts for rotary vane compressors. 

Other Compressor Types

As suggested earlier, air compressors are either dynamic compressors or positive displacement compressors. You have already looked at positive displacement compressors. In this section, you will learn more about dynamic compressors. 

Centrifugal Air Compressors 

A centrifugal air compressor is also known as a dynamic compressor with a radial design. Centrifugal compressor configuration works at constant pressure. This means that centrifugal air compressor performance depends on the inlet temperature and different external factors.

Centrifugal air compressors work by sucking air into the core. The air is then pushed to the center of the impeller by centrifugal force. The process results in a high-pressure build-up and kinetic energy. The kinetic energy is converted into pressure as the air passes through the diffuser and volute.

Advantages of centrifugal air compressors

  • Centrifugal air compressors are relatively lightweight and compact.
  • They do not require special foundations.
  • Centrifugal air compressors can supply constant compressed air for applications that need massive volumes of compressed air.
  • Centrifugal air compressors are oil-free.
  • They have fewer internal rubbing components.
  • They have high compressed air flow rate than positive displacement air compressors.
  • Centrifugal air compressors are relatively energy-efficient. 
  • Centrifugal air compressors are highly reliable and cost-effective.
  • Centrifugal air compressors are designed to offer a wide range of rotational speeds.
  • They generate a higher pressure ratio in every compression stage than axial flow air compressors.

Disadvantages of centrifugal air compressors

  • Centrifugal air compressors often experience issues, such as surging, stalling, and choking. 
  • They are not suitable for applications that need high compression with limited pressure.
  • These compressor units are sensitive to gas composition changes.
  • They require sophisticated mounting since they operate at high speed. 

Axial flow compressors

Axial compressors are designed with a drum with attached blades. 

These compressors require multiple axial stages to achieve significant pressure rise. This aspect makes axial compressors more complex and fragile. Modern axial compressor configurations can use up to 15 compression stages. 

Axial flow compressors are highly efficient and can achieve high airflow rates. They are also designed to offer compact and lightweight compressor solutions. Lastly, axial flow compressors are relatively low-cost in terms of compression volume and cost per-flow rate. 

Advantages of axial flow compressors

  • Axial flow compressors have high peak efficiency than other compressor types.
  • They have a high mass flow rate.
  • Axial flow compressors are highly efficient due to the high-pressure ratio.
  • They reduce aerodynamic drag due to the small frontal area of flow. 

Disadvantages of axial flow compressors

  • Axial flow compressors are difficult to manufacture.
  • They are also expensive. 
  • Installing axial flow compressors is more challenging since they are always heavy. 
  • Axial flow compressors require high power to compress air or start. 
  • Axial flow compressors experience a low-pressure rise per compression stage. 

The last compressor type is scroll compressors, though not discussed in detail in this article. 

Are All Air Compressors The Same?

There are many compressor types in the market, and they all perform the same function, which is to reduce air volume and increase the pressure for different applications. However, they are not all the same. For instance, dynamic compressors have distinctive designs and configurations compared to positive displacement compressors. The applications, basics, and working principles of air compressors also vary significantly. 

The Bottom Line 

When choosing air compressors, there are many options to consider. Accordingly, there are many factors you need to look into. You may want to compare costs, maintenance, size, availability, manufacturer, and longevity. Knowing the compressor type suitable for your applications is also a crucial aspect. This article has discussed different air compressor types to help you understand them and make your buying more manageable.  

White Paper: Industrial Centrifugal Air Compressor

Industrial Centrifugal air compressor applications range from chemical plants to oil and gas refineries and various on-shore and off-shore gas injection applications.

The application of a centrifugal air compressor leads to a pressure rise by incorporating velocity into a fluid flow. This velocity is then transformed into an increase in static pressure. The device achieves this by interfering with the flow and reducing it down with the help of a diffuser. 

 

The diffuser of the Industrial centrifugal air compressor converts the maximum portion of the flowing air velocity into static pressure. 

 

Industrial Centrifugal Air Compressor VS Rotary Screw 

 

Before you purchase an Industrial Centrifugal air compressor for your needs, make sure you go through enough resources highlighting centrifugal vs screw air compressors, as it will help you have a better idea of how these tools work. 

 

Rotary screw air compressors, as their name suggests, work with rotation. The rotary screw is responsible for air compression. Notably, rotary screw air compressors are less complex than reciprocating compressors. You can get a better idea of this when you compare rotary screw diagrams with centrifugal compressor diagrams. 

 

While centrifugal air compressors work differently than rotary compressors, they more or less offer similar results. What makes centrifugal air compressors a good choice is they are more efficient and it is also easier to customize them.

 

How do Industrial Centrifugal Air Compressor work?

 

Industrial Centrifugal air compressor working revolves around converting the energy utilizing multiple steps of compressing and cooling the air. In a centrifugal air compressor, the pressure developed depends on the continuous conversion of angular momentum.

 

The application of Industrial centrifugal air compressor leads to large volumes of refrigerant and that too on low pressure.  In a Industrial centrifugal air compressor, the pressure ratio is increased by the tip speed of the blade.

 

Industrial Centrifugal Air Compressor Efficiency

 

Industrial Air compressor efficiency depends on many factors, including the size and type of air compressors. As a general rule, Industrial centrifugal air compressor efficiency hovers between 0.70-0.85, while it lies anywhere between 0.65-0.75 for rotary air compressors.

 

Types of Industrial Centrifugal Compressor

Different types of Industrial centrifugal compressors are available in the market, including single-stage compressors, multistage centrifugal compressors, small Industrial centrifugal air compressors, etc. We’re going to discuss a few of them down below.

Single Stage IndustrialCentrifugal Compressor

Single-stage compressors are among the most popular Industrial centrifugal-type air compressors that come with a single impeller. The purpose of the impeller is to direct the flow of air. This type of centrifugal air compressor also includes a diffuser and guide vanes.

Prominent single-stage Industrial centrifugal air compressor examples include over-hung compressors, integrally geared compressors, and more. 

Multi-Stage Industrial Centrifugal Compressor

Multi-stage Industrial centrifugal compressors are designed to pass the air through multiple stages. These compressors are used in a wide range of applications.

Multi-stage Industrial centrifugal compressors are ideal for situations when single-stage compressors are not able to fulfill the desired pressure requirements. Examples include split-casing multi-stage Industrial centrifugal compressors, bell casing compressors, and pipeline compressors.
