Air Storage Tank Capacity

A good rule of thumb for most applications is to have three to five gallons of air storage capacity per air compressor cfm output.

Air storage tank capacity.

Sizing the recommended sizing for air compressor tanks is 4 gallons per cfm for rotary screw and piston air compressors and 2 gallons per cfm for variable drive compressors. Total volume of a cylinder shaped tank is the area a of the circular end times the length l. 3 8 to 1 4 female npt brass coupler. The tank is sized 6 10 times the flow rate of the compressor system.

A π r 2 where r is the radius which is equal to 1 2 the diameter or d 2. Air receiver tanks for portable air compressors tanks for reciprocating air compressors. What to consider when choosing air tanks. 1 4 npt brass tee.

New air compressor hose preferably coiled for neatness rtv silicone adhesive. The tank is a reservoir of compressed air that can be used during peak demand. An air receiver tank is an important component of a compressed air system. Air compressor 100 psi will require portable air compressor tank 125 psi 1 2 to 3 8 female npt brass coupler.

However there can never be enough storage for an air system. P 2 minimum tank pressure psia example sizing an air receiver. The receiver tank is usually 150 cubic feet minimum for compressors with a rating of 25 scfm at 100 psi. Air receiver tanks are sized in gallons and can range from small 5 and 10 gallon tanks to massive tanks that hold thousands of gallons of air.

So if your air compressor is rated for 100 cfm you would want 300 to 500 gallons of compressed air storage. The ideal size of an air receiver tank will depend on the type of air compressor and the application. Portable air receiver tank with a capacity higher than that of your air compressor i e. As explained above 1 3 of the total storage capacity should be wet storage and 2 3 should be dry storage.
