Average vs at-load CFM: which number belongs in the calculator?
Separate tool consumption while running from a catalog average, then calculate the demand of your own trigger schedule.
Open guide & tool →UNDERSTAND THE NUMBERSUseful calculations.
Useful calculations.
Clear assumptions.
Explore one question at a time. The examples explain what a calculation establishes and what still needs a manufacturer specification.
CFM to liters per minute: convert the unit, keep the conditions
Convert air-volume flow between CFM and L/min without changing the pressure or test basis attached to the specification.
Open guide & tool →PSI to bar: compare pressure labels accurately
Translate PSI and bar while preserving gauge versus absolute pressure and the distinction between working and maximum pressure.
Open guide & tool →Compressor duty cycle: separate the percentage from the time limit
Calculate an observed pump-on fraction and understand why a published duty percentage is only part of an operating limit.
Open guide & tool →Tank size vs airflow: what extra gallons actually change
Estimate a theoretical stored-air buffer over a pressure interval and see why tank capacity and pump delivery are separate specifications.
Open guide & tool →Air hose size: check the inside diameter, not just the fitting
Read a tool’s minimum hose requirement separately from its inlet connection and identify the information a hose check cannot establish.
Open guide & tool →Maximum tank PSI is not the pressure available at your tool
Check a basic pressure conflict, then separate tank capacity, regulation, delivered airflow and pressure under operating flow.
