Enter the piston area, stroke, and cycles per minute into the calculator to determine the pneumatic cylinder airflow rate.

Pneumatic Cylinder Airflow Formula

The following equation is used to calculate the Pneumatic Cylinder Airflow.

AF = (A*S*C) / 1728

  • Where AF is the Pneumatic Cylinder Airflow (CFM = cubic feet per minute)
  • A is the cross-sectional area of the piston (in^2)
  • S is the stroke length (in)
  • C is the cycles per minute

What is Pneumatic Cylinder Airflow?

Definition:

The airflow in a pneumatic cylinder system is the flow of air within a pneumatic system. Pneumatic cylinder systems are used in industrial and manufacturing processes to transfer force and motion from one location to another.

Gases such as air and nitrogen are compressed under pressure by a compressor then sent through a series of valves and cylinders to perform the desired task.

Three different methods can create pneumatic cylinder airflow: unbalanced, balanced, and constant-flow.

Unbalanced airflow occurs when there is no means of controlling gas flow speed through a pneumatic cylinder.

Balanced airflow occurs when the air supply determines the maximum pressure that can be used, but it is also possible to vary the pressure or volume of air being supplied to each cylinder.

Constant-flow airflow occurs when a constant air volume or pressure is maintained by a regulator downstream from an air pump, which controls the compressed air from entering the system.
