ENGINEERING GUIDE

Use the Air Receiver Fill Time Calculator to calculate time to raise receiver pressure with known compressor flow. The calculator uses Tank volume, Start pressure, End pressure, Compressor FAD and Air temperature and reports fill time.

How to interpret the result

Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are fill time. Change one input at a time when comparing scenarios so the effect of each variable remains clear.

Formula and methodology

PneumaForge applies this verified method: Ideal-gas mass balance; isothermal/adiabatic option where supported. The functional engine is shared with related tools in the receiver-storage family, while this page solves the specific intent represented by air receiver fill time calculator.

Ideal-gas mass balance; isothermal/adiabatic option where supported

Variables and inputs

Tank volume
Start pressure
End pressure
Compressor FAD
Air temperature

Worked example

Reproducible example: start with the calculator's default values (Tank volume = 1000; Start pressure = 0; End pressure = 7; Compressor FAD = 2000) and calculate the result. Then change the variable most relevant to your application and compare the new fill time against the baseline.

Assumptions and limits

Isothermal/known mean tank temperature unless a transient thermal model is explicitly selected. Absolute pressure differences represented consistently.

Engineering tips

Use absolute pressure internally even when the interface accepts gauge pressure.
State the thermal assumption for fill and blowdown calculations.
Receiver volume cannot replace adequate compressor capacity for sustained demand.
Keep the inputs used for air receiver fill time calculator on a consistent engineering basis before comparing alternatives.

Frequently asked questions
