Air Receiver tank: Principle and Calculations

The air receiver tank is an important and necessary component of the compressed air system. it helps to store compressed air it is installed after drying and filtration, and before end-use devices.

The volume of the air tank is 6-10 times the value of the flow of the compressor system. The task of the tank is to act as a buffer and a temporary storage medium for the consumption and compressor system to achieve and improve the efficiency of your factory operation.

The tank reduces the pulse in the system. The pulse is generated by a periodic process in the direction of the current or an alternating compressor. The absence of at least one device in the air system can lead to increased loading and unloading cycles on the compressor which makes it difficult to yield.

How to properly size the air receiver?

When it comes to setting the volume of the air receiver, it is necessary to allow 3-4 gallons per CFM or 10-15 liters per liter / second of compressed air depending mainly on the type of compressor used.

Several factors, along with air compressor sizing, interfere with determining the exact size of the air receiver for your fixation. The most important of these factors are:

Understanding the process

As long as the pressure is appropriate and sufficient for use only then it shows the effectiveness of the compressed air stored in the receiver.

Know the amount of CFM

In addition to the expected peaks of your machine, it is necessary to understand the position and the amount of CFM or liters / second of the required air because it imposes on you a certain percentage of compressed air to avoid a shortage in your process parts.


To operate with more compact and extended pressure ranges, the air receiver reduces the energy consumption of the compressed air system by enabling load/discharge compressors (constant speed).


To enable safe closing of production systems and processes in an emergency situation, the receiver provides air supply.
