What Are the Types of Air Compressors

What Are the Types of Air Compressors? – Shaktiman

An Air compressor is a device that converts power from diesel, electric, and gasoline engine into potential energy stored in compressed air. Based on the pressure delivered, types of air compressors are classified. 

  • The Air Discharge Pressure of 150 pounds per square inch is under Low-pressure air compressors 
  • The air discharge pressure of 151 to 1,000 pounds per square inch under Medium-pressure air compressors  
  • The air discharge pressure is above 1,000 pounds per square inch under High-pressure air compressors 

According to this threshold and work requirements, air compressor types are defined.

4 Most Common Types of Air Compressors and Their Uses

4 Types of Air Compressors

There are four common types of air compressors with their unique features & capabilities.

  1. Rotary Screw Compressors
  2. Reciprocating Air Compressors
  3. Axial Compressors
  4. Centrifugal Compressors

All the air compressors fall into two categories. One is Positive Displacement and another one is Dynamic Displacement. 

The above 4 types of air compressors come under either Dynamic or Positive.

What Is Positive Displacement Air Compressor? 

A mechanism of the Positive Displacement air compressor is to draw air into the chamber. Then the volume of this chamber decreases which will compress the air. A valve will open, and the air is then discharged into the outlet system once maximum pressure is reached. Rotary screws and reciprocating air compressors fall under this division. 

What Is a Dynamic Displacement Air Compressor? 

Dynamic Displacement air compressor speeds up the air to high velocity and then limits the airflow from the chamber. Because restriction in rate causes pressure to increase. Axial Compressors and Centrifugal Compressors fall under this division.

1. Rotary Screw Compressors

Rotary Screw Air Compressors are compressors that use the mechanism of rotary-type positive displacement mechanism. It mostly comes to replace piston air compressors in industrial areas. Because the industrial application needs a large amount of compressed air.

2. Reciprocating Air Compressors

A reciprocating air compressor is also the type of positive displacement compressor in which air is sucked into a chamber and compressed with the help of a reciprocating piston. There are four kinds of Reciprocating Air Compressors

  • Single acting Reciprocating air compressor
  • Double-acting Reciprocating air compressor
  • Single-stage Reciprocating air compressor
  • Double-stage Reciprocating air compressor.

3. Axial Compressors

An axial Air Compressor is an air flow-based air compressor in which airflow or gas flows parallel the axis of rotation, or axially. It converts the circumferential component of flow into pressure with the help of the stationary blades to slow the fluid. 

4. Centrifugal Compressors

Sometimes Centrifugal air compressor is also called radial compressors or impeller compressors.  By adding energy to the continuous flow of fluid through the impeller, high pressure is achieved.

These are the four types of air compressor and their work mechanisms. Based on the requirement of your business you can buy suitable air compressors from the right air compressor dealers.

What Everyone ought to know before buying Air Compressor

Important Questions to Discuss before Buying an Air Compressor

In this article, We will guide you with some pro tips about air compressors & acknowledge about air compressors. In recent years people have had common questions to discuss which help to choose an air compressor that matches our requirement. Most of the customers don’t get satisfied because they will not check life expectancy. Don’t buy a compressor unless the dealer can tell you the expected life. Apart from this most common question about air compressors are

1. How Does an Air Compressor Work?

An air compressor is used to create pressured air using electrical power, then discharging and converting for use in several applications to usable power

The air in the chamber is compressed by a piston, rotary vane, or screw, or slider, and then this pressured air is transferred into the downstream receiver and the distribution piping system.

2. What Does an Air Compressor Do?

Air compressors offer compressed air for packages along with filling gasoline cylinders with high-pressure air, presenting pressurized fresh air for working pneumatic HVAC structures or tools, filling tires, and a huge kind of different packages throughout industries like automotive, medical and beverage, petroleum, etc.

3. In an Air Compressor, How Often Do Have to Change the Oil?

You will need to change the oil from time to time if you have a lubricated reciprocal, rotating screw, or rotating air compressor to make it work properly. The schedule is generally recommended for three months, subject to the recommendation of the manufacturer. For a rotary compressor, depending on the type of oil used, you want to change the oil every 4,000 to 8,000 hours.

4. Does It Need a Dryer for the Air Compressor?

The fact that your air compressor can bring a lot of water into the compressed air system is often of good value to you. Every day, your air dryer might remove gallons of water.

5. In a Compressed Air System, How to Control Contaminants?

To keep your compressed air clean you need an efficient air filtration system.

  1. Concentrating on current contaminants.
  2. Insist on filters that are wetly tested
  3. More reliable monitoring and preventive maintenance.
  4. A zero-loss drain prevents loss of compressed air.
Question about air compressor

6. How to Drain the Water from Tank of the Air Compressor?

You can drain manually or buying an automatic drain valve to automatically remove the water. If the water becomes a big issue, consider investing in a better air dryer.

7. Where Is the Compressor Location Going to Be?

The intake air of the compressor must be clean and free of solid gases. Particularly harmful to dirt causing wear and corrosive gases.

In the sound reduction case, the air inlet of the compressor is usually located at the opening but can be placed remotely, where the air is so clean as possible.

8. How Much Cfm Needed? How Much Airflow?

(CFM) means cubic feet per minute.

  • Not only do oversized compressors cost more money but use more power that is more costly in the long run.
  • Be aware that CFM is not the volume produced under optimum conditions, in particular during our summer days – on 90° F 70 percent Rh, you can lose up to 20 percent of the capacity.
  • Take a load cycle for all shifts on your existing compressor. Better yet, for nominal costs install a flow meter that can save you in the long run thousands.
  • You can adjust to what you consider to be future growth once you decide what your flow requirements are.

9. Which Is the Top Branded Air Compressor?

There are so many top branded air compressors that used in many industries in recent years.

Quincy Compressor

There is a Quincy air compressor that will assist you in working efficiently and keep overhead costs but reliable for any industry that is operating under compressed air. These products can be found hard in mechanic garages and car body shops, factories, theme parks, energy exploration, college, dental shops, and much more.

Advantages of using Quincy air compressor has some best working conditions in environments & stable air pressure provided, but disadvantages are lack of life expectancy.

Elgi’s air compressor  

Elgi is best at CMF and airflow. In addition to clean air, its compressed air solution was also needed to be cost-efficient and energy-efficient & also Low energy consumption and built-in VFD helped ELGi compressor save 50 percent of their electricity costs. In addition, they are also compact air compressors that have minimal floor space.
