Industrial Fans, Blowers & Air Movement Equipment calculator

Static Pressure Power Calculator

Use this calculator to connect fan static pressure decisions with energy cost. It is useful when comparing higher efficiency wheels, duct changes, damper settings, motor options, or dust collector pressure drop scenarios.

What this calculator does

  • Estimate operating energy cost for a fan or blower from connected motor load, runtime, electricity price, and fan count or test count.
  • Use it when evaluating the cost impact of static pressure, duct loss, filter loading, damper position, or motor selection.
  • The result estimates energy cost tied to the selected fan load and runtime.

Formula used

  • Fan energy cost = connected fan motor load × fan operating runtime × blended electricity price
  • Static pressure power cost per fan = fan energy cost ÷ fans or test units covered

Inputs explained

  • Connected fan motor load: Use measured kW, nameplate kW adjusted for load, or expected brake power converted to kW.
  • Fan operating runtime: Enter the hours for the shift, test run, production batch, month, or annual scenario.
  • Blended electricity price: Use the delivered electricity cost including demand assumptions if that is how your plant evaluates energy.
  • Fans or test units covered: Enter the fan count, blower count, or test units sharing this energy cost basis.

How to use the result

  • Use it to compare pressure drop reduction, efficient wheel selection, VFD control, or motor sizing options.
  • It does not replace a full fan system energy audit with measured airflow, pressure, and power.

Common questions

  • What is the static pressure power calculator for? It estimates energy cost for a fan or blower operating at a connected load.
  • What information should I enter? Use connected motor load, runtime, electricity price, and fan or test count.
  • What does the result tell me? The result helps compare pressure loss, damper, motor, and efficiency scenarios in cost terms.
  • When is the result only an estimate? It is only an estimate when actual brake horsepower, duty cycle, demand charges, or static pressure changes.
