How much air should be in a compressed air tank?
3 min read
Asked by: Brad Salvadora
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.
How much air is in a compressed air tank?
It means that 80 cubic-feet of air at sea-level air pressure are contained in the tank. Air pressure at sea level is approximately 14.7 psi. Now, follow this. If you compress 80 cubic-feet of air to 3,000 psi, that’s compressing it 204.08 TIMES.

What is the normal capacity of an air tank?
Most standard tanks are rated for use between PSI, but if you need something able to handle more, don’t worry, 300 to 3000 PSI units are available for high-pressure applications. Receiver tank capacities can range from 10 to 10,000 gallons and can be sized by using the formulas listed below.

How is compressed air tank calculated?
t = V (p1 – p2) / C pa
- V = volume of the receiver tank (cu ft)
- t = time for the receiver to go from upper to lower pressure limits (min)
- C = free air needed (SCFM)
- pa= atmosphere pressure (14.7 PSIA*)
- p1 = maximum tank pressure (PSIA)
- p2 = minimum tank pressure (PSIA)
What is the safe pressure for compressed air?
30 PSI
If you must clean the workspace or equipment with compressed air, do not use air set above 30 PSI. 30 PSI is sufficient for removing dirt and debris, any higher can be a threat to workplace safety.
What does 150 PSI mean on an air compressor?
PSI= This stands for pounds per square inch, which refers to how much pressure your tire compressor is able to put out. For example a tire compressor with a PSI of 150 will be able to fill up a tire faster than a tire compressor with a PSI of 100.
Is 100 PSI enough for an air compressor?
Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute (cfm) at 70 to 90 pounds per square inch (psi), whereas with larger tools connected to stationary systems, the requirements usually exceed 10 cfm at 100 to 120 psi.

What is the maximum pressure that should be used with compressed air nozzles?
Compressed air used for cleaning purposes must be regulated to keep the pressure below 30 psi, or must use a nozzle with relief holes or other safety features (e.g., star tipped nozzle) that limit the air pressure to 30 psi or less when dead-ended (i.e., when the primary nozzle opening is held against a flat surface).
Can compressed air explode?
Can compressed air explode? It is possible for an air receiver tank holding compressed air to explode—but it’s extremely rare and tends to occur when operators don’t look after their air receiver tank. The leading cause of air compressor tank explosions is corrosion.
What pressure does OSHA allow for shop air?
The enclosed Occupational Safety and Health Administration (OSHA) standard 29 CFR 1910.242(b) requires that compressed air used for cleaning purposes must be reduced to less than 30 psig (pounds per square inch gauge, 204 kPa).
What does OSHA consider high pressure?
High Pressure: Gas pressure greater than 20 MPa gauge (3000 psig) and liquid pressure greater than 35 MPa gauge (5000 psig).
Can you get an embolism from compressed air?
On rare occasions, some of the compressed air can enter the blood stream through a break in the skin or a body opening. An air bubble in the blood stream is known medically as an embolism, a dangerous medical condition in which a blood vessel is blocked, in this case, by an air bubble.
