Storage System Sizing Chart

Instructions:

  1. Select the type of BA cylinder to be filled from top of the chart.
  2. Find the fill method and desired number of storage vessels in the left column.
  3. Select the starting pressure of DOT storage, either 5000 or 6000 psi.
  4. Intersect the cylinder type with the number of storage vessels to determine the number of cylinder fills and RF.

*Residual factor (RF) represents residual storage volume which may be utilized in conjunction with a compressor to fill BA cylinders when storage pressure alone is insufficient to fill the cylinders to capacity. By adding compressor cylinders filled per hour, cylinders filled from storage, and RF, the maximum number of cylinders filled from a complete air system may be determined.
