We have also included a chart below to give you an example of how many fills you can obtain from your storage system before you need to rely on your compressor to top up your SCBA. As you can see storage is critical during an emergency on how may SCBA bottles you will be able to fill. We have eliminated the part of the chart which shows bulk fills as this is not an efficient way to use your air storage.
Fills from Storage
- Select the type of BA cylinder to be filled from top of the chart.
- Find the fill method and desired number of storage vessels in the left column.
- Select the starting pressure of DOT storage, either 5,000 or 6,000 psi.
- Intersect the cylinder type with the number of storage vessels to determine 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.
