Air storage tank capacity.

New air compressor hose preferably coiled for neatness rtv silicone adhesive. A π r 2 where r is the radius which is equal to 1 2 the diameter or d 2. What to consider when choosing air tanks. 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. 1 4 npt brass tee. The tank is a reservoir of compressed air that can be used during peak demand. So if your air compressor is rated for 100 cfm you would want 300 to 500 gallons of compressed air storage.

The receiver tank is usually 150 cubic feet minimum for compressors with a rating of 25 scfm at 100 psi. Portable air receiver tank with a capacity higher than that of your air compressor i e. Air compressor 100 psi will require portable air compressor tank 125 psi 1 2 to 3 8 female npt brass coupler. As explained above 1 3 of the total storage capacity should be wet storage and 2 3 should be dry storage.

3 8 to 1 4 female npt brass coupler. Total volume of a cylinder shaped tank is the area a of the circular end times the length l. An air receiver tank is an important component of a compressed air system. A good rule of thumb for most applications is to have three to five gallons of air storage capacity per air compressor cfm output.

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. 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. 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.
