Compressed Air Tank Guide

There are many parts of an air compressor – and air tank is one of the most significant ones. An air receiver is similar to a pressure vessel. Its function is to hold the compressed air under pressure and store it for future use. You can use this compressed air later for any use without the need of running your air compressor.

The function of an air receiver can easily be understood by its name. Its purpose is to collect and carry the compressed air until it is used for a task. This way, you can use the compressed air whenever you want without running your air compressor. You can find a range of air receiver tanks in different sizes and in vertical as well as horizontal configurations.

Purpose of an Air Tank in an Air Compressor

The purpose of an air tank is to collect and store the compressed air for future high-demand events.  It will help your system operate more constructively. The three main functions purposed by air tanks are:

  • It stocks compressed air used for short and high-demand events.
  • Provides a subtle air signal to the compressor controls.
  • It plays the role of a heat exchanger is used as a wet tank

To further explain these purposes:

1.   Air Storage

The principle of an air receiver tank is to store compressed air in it. This will help your system have compressed air at every time even if the compressor is running. This compressed air will help power events that go up to 30 seconds or so. This stored compressed air decreases the sudden demand for your air compressor.

The use of an air receiver tank will allow you to use a small horsepower compressor for comparatively greater jobs.

2. Compressor Control

A steady signal is sent from the air receiver tank to the compressor controls. It provides a subtle stream of air that is used to compress and eliminate over-pressurization and short-cycling. An uneven demand is created due to the consumption of uneven compressed air. At this point, the air compressor starts to rapidly turn on and off in order to fulfill its moment-by-moment demand. The role of an air tank is to eliminate short cycles and provide a more consistent pressure system.

3. Heat Exchanger

This can be easily understood by the Pressure-Temperature Law. The air discharged from the compressor is usually hot, depending upon the type of compressor you are using, it may be as hot as 250 – 350 degrees Fahrenheit. This is too hot for the air inside the compressor and may cause vapors inside. This condensed air should be cooled before it is used further.

A heat exchanger will remove the heat caused by compression. An air receiver tank works as a heat exchanger as it cools down the compressed air.

An operating mechanism creates and stores the energy to operate a circuit breaker. Compressed air becomes the energy source for the Pneumatic operated mechanism for closing and tripping the hi-voltage circuit breakers. These pneumatic circuit breakers are called “Air Blast Circuit Breakers.”

The air compressor stores the compressed air in the storage tank (air receiver). When needed, it is blasted into the arc extinction chamber. This pushes away the moving contact. As a result, the connections are pulled apart, and the air blast moves the ionized gas away along with it and supports the arc extinction.

Benefits of an Air Receiver Tank

There are multiple benefits of an air receiver tank including:

Reduce Waste of Compressed Air

The air compressor vents a large amount of compressed air after every single cycle. This compressed air is highly valuable as it can be used to operate high or short-demand events. This loss of thousands of cubic feet of compressed air is a significant loss. A proper air receiver tank will help you to store this compressed air and reduce the waste of compressed air after each cycle.

Reduce Air Compressor Operating Pressure

If an air compressor doesn’t have an air tank to store the excess compressed air, the compressor will have to work on high pressures in order to meet the high demands at every time. In other words, the compressor will be working at all times at maximum demand.

Having an air receiver tank would result in lower energy costs by operating at a lower pressure you’re your system, resulting in efficient work and better results. 

Improved Efficiency

The air receiver tank improves the efficiency of an air compressor. With each cycle, the compressor vents out compressed air. The presence of an air tank results in the storage of that compressed air and will reduce the wastage of compressed air resulting ineffective operations and lower costs.

Improved Efficiency for Dryers

As mentioned above, the air receiver tank plays the role of a heat exchanger and naturally cools down the heat causing minimum vapors and less moisture. This increases the efficiency of the air dryer – the air receiver tank reduces the amount of work done by the air dryer.

Improved Efficiency for Coalescing Filters

The removal of moisture done by the air receiving tank allows the filters to be relatively dry and thus improves the efficiency of the coalescing filters.

What are Air Tanks made up of?

The Air tank is a highly essential part of an air compressor. It is made up of steel. The exterior of the air tank is coated with the material used to prevent corrosion. This steel material is cost-effective, durable, and is a strong material that can stand strong in all tough environments. This makes it easier for them to adapt to any commercial or industrial application.

Wet Air Storage vs. Dry Air Storage

Whilst choosing an air receiver tank (storage facility for the air compressor), it is important to know your requirement and which kind of storage is needed for your air compressor. There are 2 significant kinds of air tanks – Wet Air Storage and Dry Air Storage.

Wet Air Storage

A wet storage air tank is installed before the air drying system. Air flows in the configuration through the bottom of the compressor and leaves from the top of the dryer. A few of the main functions of wet air storage includes:

  1. Isolates the compressor from the demand events
  2. Reduces the compressor cycles
  3. Let’s the compressor to stay unloaded for a long period of time
  4. Performs as a backup if the compressor fails

Dry Air Storage

Dry air storage is installed after the air dryer. It is installed in order to store the already dried compressed air to reach its desired level of application. The main features of a dry air storage tank include:

  1. Dry compressed air is available in case of a high-demand event or a supply failure.
  2. A dry storage tank reduces the burden and increases the efficiency of an air dryer in high-demand events.
  3. There are many applications that require the need of a mix of dry and wet storage for optimal performance.

Wet to Dry Compressed Air Storage Ratio

As for those applications that require a combination of dry and wet air receiver tanks, there is an ideal ratio of wet to dry – 1/3rd wet to 2/3rd dry capacity. In such an application, dry air is always ready to use on-demand and the wet air tank acts as a secondary reserve when the dry air is bushed. Here, the existence of a wet air tank lessens the risk of over-capacitating the dryer throughout high-demand events.

Internal Lining of the Air Receiver Tank

If you are selecting the inner lining of your tank, there are three main options.

  1. Bare steel internal with primer outer
  2. Epoxy layered
  3. Stainless steel

Selection Criteria

The need for an air receiver tank is known as how much storage is needed by the facility. It also varies from application to application. A few of the most impactful factors are:

  • The capacity of an air compressor – CFM
  • Peak CFM requirement in high-demand events
  • Consistency of the airflow
  • Diameter of the pipe

Whilst selecting the right storage tank for your air compressor, keep in mind the above-mentioned factors. Ideally, a good rule of thumb suggests three to five gallons of air storage capacity per air compressor CFM output, for a majority of applications out there.

Flow consistency plays a significant role in deciding the requirement of your air tank for your air compressor. Facilities with a stable and steady airflow usually don’t need much-stored air for their routine tasks. For these facilities, air storage can be decreased to 2 gallons rather than the ideal 3-5 gallons.

Facilities with more variability in airflow entail large volumes of stowed compressed air. This extra capacity will ensure the system works efficiently in high-demand events. The required air storage can be determined by testing the CFM at its peak demand.

The size of the pipe in the facility plays a vital role in deciding the size of the air receiver tank. These pipes also store the air for the system. We can say that bigger pipes can store a larger amount of compressed air. Ideally, 2″ of pipes are worthwhile for storing the compressed air for an air compressor.
