Air Storage Tank Capacity

A π r 2 where r is the radius which is equal to 1 2 the diameter or d 2.

Air storage tank capacity.

V tank π r 2 l calculate the filled volume of a horizontal cylinder tank by first finding the area a of a circular segment and multiplying it by the length l. Air compressor 100 psi will require portable air compressor tank 125 psi 1 2 to 3 8 female npt brass coupler. 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. The tank is sized 6 10 times the flow rate of the compressor system.

For an air compressor system with mean air consumption 1000 cfm maximum tank pressure 110 psi minimum tank pressure 100 psi and 5 sec time for the receiver to go from upper to lower pressure the volume of the receiver tank can be calculated by modifying 1 to. What to consider when choosing air tanks. New air compressor hose preferably coiled for neatness rtv silicone adhesive. 3 8 to 1 4 female npt brass coupler.

However there can never be enough storage for an air system. So if your air compressor is rated for 100 cfm you would want 300 to 500 gallons of compressed air storage. An air receiver tank is an important component of a compressed air system. Portable air receiver tank with a capacity higher than that of your air compressor i e.

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. P 2 minimum tank pressure psia example sizing an air receiver. As explained above 1 3 of the total storage capacity should be wet storage and 2 3 should be dry storage. Total volume of a cylinder shaped tank is the area a of the circular end times the length l.

The receiver tank is usually 150 cubic feet minimum for compressors with a rating of 25 scfm at 100 psi. V t c p a. The tank is a reservoir of compressed air that can be used during peak demand. A good rule of thumb for most applications is to have three to five gallons of air storage capacity per air compressor cfm output.
