Technical data

Bulk storage for limiting the number of compressor starts to 4 times per hour can be calculated by the following formula:

WORKING PRESSURE
psig
ΔP
(psig)
4500 450
5000 500
6000 600

Cubic Feet = Gallons x 0.134
Gallons = Cubic Feet x 7.48

VR = 58 x (QC / ΔP)

Where:

  • VR = Volume of storage, cubic feet water volume
  • QC = Capacity of compressor, standard cubic feet per minute (scfm)
  • ΔP = Approximate deadband of final pressure switch, pounds per square inch (psig)

Multiple cylinders can be used for applications that require a large volume of storage.
Contact BAUER for sizing storage with multiple banks for cascading.

TECHNICAL DATA FOR GASES AT PRESSURE

The table below list the volume of different gases that can be compressed into one (1) cubic foot water volume at the given pressure. The information is based on 70° F and accounts for the compressibility of the gas. The table can be used to calculate the volume of air or gas that can be stored in a cylinder of known water volume. Likewise, the water volume of a cylinder can be calculated if the capacity of air or gas stored in the cylinder is known.
