Use the Air Blow-Off Cost Calculator to calculate energy/cost of continuous or intermittent air blow. The calculator uses Blow-off flow, Duty cycle, Operating hours per year, Specific energy kWh per m³(ref) and Electricity price and reports air, energy and annual cost.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are air, energy and annual cost. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Flow × duty × time × specific energy. The functional engine is shared with related tools in the air-blow-economics family, while this page solves the specific intent represented by compressed air blow off cost calculator.
Flow × duty × time × specific energyReproducible example: start with the calculator's default values (Blow-off flow = 500; Duty cycle = 50; Operating hours per year = 4000; Specific energy kWh per m³(ref) = 0.1) and calculate the result. Then change the variable most relevant to your application and compare the new air, energy and annual cost against the baseline.

It is designed to calculate energy/cost of continuous or intermittent air blow. The reported outputs are air, energy and annual cost.
The calculator uses Blow-off flow, Duty cycle, Operating hours per year, Specific energy kWh per m³(ref) and Electricity price. Only use values that represent the same operating condition or design case.
The calculation follows: Flow × duty × time × specific energy. The page also states the assumptions that define where the method is valid.

Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
