Air storage tank size

What size air tank do I Need?

The peak demand or most common sizes include 5,7,9,10 and 11-gallon air receiver tanks. The smaller the air tank (gallon number), you guessed it, the smaller the air compressor, and the easier it is to transport or have portable air. The bigger the air tank, the more suited it may be for most applications but the more difficult it will be to move.

How big is an air receiver tank?

In most cases, a receiver tank is sized at 2 gal/scfm. However, if big surges in demand are expected, the size is increased to between 4 and 10 gal/scfm. The following article goes into further detail about what an air receiver tank is, why it is important, and how to properly size one for a compressed air system. What Are Air Receiver Tanks?

How many gallons of air storage do I Need?

The consistency of airflow. The diameter of the piping. A good rule of thumb for most applications is to have three to five gallons of air storage capacity per air compressor cfm output. So if your air compressor is rated for 100 cfm, you would want 300 to 500 gallons of compressed air storage.

What is a compressed air tank?

Compressed air tanks are sealed volumes that are typical of a welded construction strong enough to contain the required pressure. They’re filled by a compressor unit, typically mounted on the tank itself – and they discharge air into compressed air piping systems via an outlet. An air compressor typically operates on a demand basis.

How do I choose a receiver tank for a compressed air system?

Some of the key factors to consider when choosing a receiver tank for a compressed air system are: Size: An air receiver tank should be sized between 6–10 times the flow rate of the system. For example, compressors with a rating of 25 scfm at 100 psi should have a tank that is size at a minimum of 150 cubic feet.

How big should my tank be?

So how big should your tank be? Our team recommends having a minimum of 2 gallons storage for every cubic foot per minute (CFM) created by your machine. Ideally, we will recommend having 4 gallons of storage per CFM. Here's a sheet showing the correct conversions for recommended tank size based on the horsepower and CFM of your machine.
