In addition, the air consumption vary due to the process supported. In shorter periods the demand for compressed air may even exceed the maximum capacity of the compressor. In fact, it is common in well designed systems not to design the compressor for the maximum peek loads. Air receivers in compressed air systems serves the important purposes of

Equalizing the pressure variation from the start/stop and modulating sequence of the compressor.
Storage of air volume equalizing the variation in consumption and demand from the system.

In addition the receiver serve the purpose of: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Collecting condensate and water in the air after the compressor.

Sizing the Air Receiver :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

The variation in the consumption demand.
The compressor size and the modulation strategy.

In general it is possible to calculate the maximum consumption in the system by summarizing the demand of each consumer. The summarized consumption must be multiplied with a

Usage factor ranging 0.1 - 1

depending on the system. In practice it is common that the manufacturer use standardized receivers for specific compressor models based on their know-how.
For calculating the receiver, note that it is necessary with a pressure band for the receiver to be effective. If the consumption process requires 100 psig and the compressor is set to 100 psig, there is no storage and no buffer. Any increased demand makes a pressure drop below 100 psig until the compressor controls respond by increasing the volume compressed.
If the compressors operates at 110 psig the difference between 110 psig and 100 psig accounts for the air stored in the receiver.
If the demand increase, the pressure can drop 10 psig before the minimum requirement is met. Pressure and flow controllers can be used after the receiver for stabilizing downstream pressure to 100 psig and flattening demand peaks. Note that in a compressed air system the pipe work also makes the purpose of a buffered volume.
The receiver volume may be calculated with the formula
t = V (p1 - p2) / C pa (1)
where
V = volume of the receiver tank (cu ft)
t = time for the receiver to go from upper to lower pressure limits (min)
C = free air needed (scfm)
pa= atmosphere pressure (14.7 psia)
p1 = maximum tank pressure (psia)
p2 = minimum tank pressure (psia)
It is also common to size receivers.

To 1 gallon for each ACFM (Actual Cubic Feet per Minute), or
4 gallons per compressor hp (horse power)

1 ft3 = 0.02832 m3
1 inch = 25.4 mm
1 psig = 6.9 kPa = 0.069 bar
1 Gallon (U.S.) = 3.785x10-3 m3 = 3.785 dm3 (liter) = 231 in3
