The air storage tank is the supporting equipment of the air compressor. The air enters the compressor and then is pressurized and then sent to the air storage tank, and then is supplied to each location by the air storage tank pipeline. The main function of the air storage tank in the air compression system is to ensure a stable gas supply.

The compressed air deposits water in the air storage tank adjusts the air pressure fluctuation of the pneumatic equipment due to the unbalanced air consumption, increases the pressure stability of the air equipment, or reserves a part of the compressed air, which can be used by the user when the air compressor fails. This part of the compressed air is used for emergency treatment of pneumatic equipment or pneumatic control systems

Understanding Compressor Air Tank Better

What is a compressor air tank? And how would you know if you need one? This guide to compressed air receiver tanks will answer your questions by explaining how it works, what they do, and how they can be used to maximize the efficiency of compressed air from your air compressor.

What Is a Compressed Air Tank?

As the name goes, an air receiver tankor the air compressor tankis a tank or cylinder that receives and stores air after it leaves the air compressor. It allows you to have a compressed air reserve that you can use without having to run the air compressor. An air receiver tankcan be described as a pressure vessel that holds your compressed air under a certain level of pressure for you to use when the need arises. Air tanks come in a wide range of sizes and designs (vertical and horizontal).

Why Do You Need an Air Receiver Tank?

A compressor air tank is essential in providing temporary storage for compressed air before it is used. Additionally, it helps the air compressor system run more efficiently. Generally, an air receiver tank has three primary functions in a compressed air system.

  1. It stores compressed air temporarilyto be used when there is the demand.
  2. It offers steady air signs to air compressor controls.
  • Wet compressor tanks play the role of secondary heat exchangers by improving the efficiency of the air dryer.

Wet vs. Dry Compressor air tanks: What is the Difference?

When you decide to buy an air compressor air tank, you may have to choose between a wet and dry compressed air storage tank.The difference between these two is just the location of the tank in the compressed air system. This means that there is no difference in the design or construction between the two.

Wet compressed air tanks are found before the compressed air-drying system. Compressed air flows through the tankby entering through the bottom port from the air compressor and leaves through the top of the compressor dryer.

On the other hand, a dry compressor air tank is found after the air dryer, and it stores compressed air that is already dried and filtered.


Benefits of Wet Compressed Air Storage

Inan air compressor’s wet air storage system, the air receiver tankis located between the air compressor and the compressor air dryer. Wet air flows into the receiver tank from the air compressor through the bottom port and leaves through the upper part of the port into the air dryer. Wet air receiver tanksoffer several benefits.

  • Wet receiver tanks improve the efficiency of the air dryer by allowing excess moisture and oil to condense out of the compressed air before hitting the compressor air dryer.
  • Wet receiver tanks extend the life span of pre-filter elements in an air compressor, which are found between the tank and the air dryer. The air going through the filter is often cleaner and dryer than it would have been when going directly out of the air compressor. In the absence of the wet receiver tank, the filters would be slugged with moisture, resulting in pressure drop.
  • The air compressor does not experience what is called backpressure. This is because compressed air does not enter the filtration system before entering the air tank. In the end, your air compressor experiences a steadier pressure signal in the compressor controls.

Benefits of Dry Compressed Air Storage

Dry, compressed air storage tanks also come with various benefits. Dry compressed air is often ready to be used directly from the compressed air receiver tank.

In the absence of a dry air tank, compressed air from the wet receiver tank would have to go through the compressor air dryer before it is used. Under a high-demand situation, the dryer becomes prone to over-capacitation as the compressor system tries to provide high volumes of air than the rating of the compressor air dryer. If the air dryer fails to keep with the demand for compressed air, the air-drying efficiency is highly reduced, and this may lead to unwanted water and oil in the air lines.

What Size of Air Tank Do You Need for Air Compressor?

The size of your compressed air storage system will depend on the following factors:

  • The capacity of your air compressor, measured in cubic feet per minute (CFM0
  • Peak CFM required by your air compressor in periods of maximum demand.
  • The consistency of the flow of air
  • The size (diameter) of the piping


Can the Air Receiver Tanks Be Stored Outdoors?

Compressed air tanks can sometimes be bulky, and therefore, most owners like keeping them outside. Storing them outdoors will save you precious space in your facility. Additionally, it will help in reducing the strain on your HVAC system during warm weather. The compressor air tank radiates heat, allowing hot air from the air compressor to cool within it, resulting in higher temperatures in the storage room. When the tank is kept outdoors, there would be no excess heat buildup in the storage room, and this helps the air tank act as a heat exchanger more efficiently.

However, storing your compressor air tank outdoors is only suitable in non-freezing weather. You have to ensure that the climate is favorable for storing the air tank outside.

Tips for Storing Your Air Receiver TanksOutdoors

If you decide to keep your air receiver tank outside, ensure you frequently check it for corrosion. Any sign of corrosion should be taken care of immediately to protect the air tank from unnecessary wear.

Accordingly, if you live in areas that experience low temperatures, you have to take special care of your air tank. The tank is expected to generate some heat. However, if the temperatures are too low, the tank may be at risk of freezing. In that case, you should insulate the tank to provide some auxiliary heat to prevent unnecessary damage.

Steel Air Receiver Tanks

A majority of air receiver tanks you will find are made of bare steel on the inside and a primer coating on the outside to prevent corrosion. A standard steel air tankworks optimally for many compressed air applications and is the least costly option in the market. However, steel airtanks may be prone to corrosion if liquids build up inside the air tank.

Galvanized and Epoxy Coated Air Receiver Tanks

Some air tanks are designed with interior linings to reduce corrosion and improve the quality of compressed air. The interior liners fall into two categories.

Epoxy coatings are sprayed in the liquid form and then cured into a tough, corrosion-resistant coating. The epoxy coating works best by creating a barrier between the air and the surface of the air tank.

On the other hand, galvanized air tanks are treated with a zinc coating to reduce corrosion. Zinc reacts with corrosive chemicals and therefore prevents them from reaching the surface of the air tank.

Both methods are useful in protecting the interior of the compressor air tank for ages, but they come at an extra cost and lead time. Coated or galvanized air tanks offer high-quality compressed air by reducing the chances of particulates caused by corrosion being found in compressed air. If your applications require quality compressed air or if you want your air tank to serve you for long, you may want to consider these two options.

Stainless Steel Air Receiver Tanks

Stainless steel air tanks are specifically designed for applications that require high quality compressed air. These types are the costliest but are highly durable and resistant to corrosion.

Air Receiver Tank Accessories

Air receiver tank components are essential for the safety and operation of the tank. As much as the tank is just a sizeable sealed metal vessel, it requires some of these accessories.

  • Electronic Auto Condensate Drain

The automatic drain valves are essential in eliminating the need for manual draining of liquid inside the tank.An automatic drain valve is set to let accumulated liquid out of the tank at intervals.

  • Zero Air-Loss Condensate Drains

This component is another one that offers automatic drainage of liquids out of the tank. Instead of draining in intervals, they have float mechanisms to regulate drainage. The drain valves open when the liquid accumulates to a certain level, and they are therefore more energy-efficient and reduce the loss of compressed air from the receiver tank.

  • Pressure Gauges

The pressure gauge is used to check the air pressure in the receiver tank. The gauge is essential in monitoring of pressure and ensuring that the receiver tank is not under immense stress as a result of very high pressure.

  • Pressure Relief Valves

OSHA and ASME guidelines require that all air receiver tanks have a pressure relief valve. The pressure relief valve is essential in reducing the air pressure inside the air tank by opening automatically to release some air if the pressure inside the tank is too high. This is a safety mechanism that prevents the tank from rupturing due to over-pressurization.

  • Vibration Pads

Vibrations pads may not be necessary for all applications. However, they are crucial in case your air compressor is mounted on top of the air receiver tank. These components absorb the vibration from the air compressor motor to reduce fatigue on the air tank.


Air Receiver Tank Safety

Air receiver tanks store air under high pressure. This situation often creates safety hazards, especially when the tank is not compliant with industrial codes and when not maintained properly.

Causes of Air Receiver Tank Failure

Pressure vessels are supposed to be designed in a way that can withstand high pressure for longer durations. As time passes by, corrosion, stress, and fatigue can cause air tank failure. The most common causes of air tank failure can be:

  • Use of non-code air tanks that are faultily designed.
  • Operating the tank above the maximum allowable working pressure.
  • Corrosion
  • Cracking
  • Improperinstallationof the tank and its components
  • Improper maintenance, such as failed repairs and leaks
  • Failure in safety valves
  • Exposure to extreme weather conditions.

Air Receiver Tank Occupational Hazards

Air receiver tanks hold air under immense pressure, and this makes failures extremely hazardous. Any crack or weld failure can lead to an explosion, projecting metal fragments at high speed. Air receiver tank failure can cause extensive damage to the working facility and equipment within the room. Workers are also exposed to injuries, and in some cases, death.

Maintaining Air Receiver Tank Safety

You have to follow all safety measures and guidelines, as stated in the owner’s manual for your air receiver tank. The first steps into improving safety include:

  • Ensuring that you only use certified air receiver tanks.
  • You should never put the air receiver tank under immense pressures above its ratings.
  • Ensure that your air receiver tank has a pressure gauge to help you monitor pressure inside the air tank.
  • Take time to inspect the tank after some time to ensure that it is corrosion-free and does not show any signs of a seamstress, cracks, and any other notable defect.
  • Ensure that your tank ahs safety pressure relief valves.
  • Darin your air receiver tank frequently to prevent the accumulation of water inside the tank.
  • Have your repairs completed by certified professionals only.

The bottom line

Your compressed air receiver tank is an essential component of the air compressor. Having the right size of the air tank will ensure that your operations are safe and efficient by allowing youto have enough compressed air at all times. Additionally, compressor air tanks reduce the need to have your air compressor refilled frequently because you have reserve storage at all times. The reserve comes in handy at times of peak demand for compressed air.
