Industrial Filtration, Separation & Dust Collection calculator
Fan Horsepower Calculator
Use this calculator to estimate the energy cost tied to dust collector fan horsepower. It is useful when pressure drop, air-to-cloth ratio, duct loss, damper position, or filter loading changes the load on the collection system fan.
What this calculator does
- Estimate fan horsepower energy cost from connected fan load, runtime, electricity cost, and collectors or units served.
- Use it when evaluating dust collector fan power, pressure drop changes, airflow increases, or motor and fan upgrade options.
- The result estimates energy cost for the selected fan load and operating period.
Formula used
- Fan energy cost = connected dust collector fan load × fan operating runtime × blended electricity price
- Fan horsepower energy cost per served collector = fan energy cost ÷ collectors or lines served
Inputs explained
- Connected dust collector fan load: Use measured fan kW, motor load, or brake horsepower converted to kW for the collector operating point.
- Fan operating runtime: Use shift, monthly, annual, or test runtime for the dust collection fan scenario.
- Blended electricity price: Use delivered electricity cost including demand assumptions if your plant includes them.
- Collectors or lines served: Enter the collectors, production lines, filter modules, or units sharing this energy cost basis.
How to use the result
- Use it to compare fan upgrades, pressure drop reduction, VFD operation, or filter replacement timing.
- It depends on actual fan load, airflow, pressure drop, duty cycle, motor efficiency, and utility pricing.
Common questions
- What is the fan horsepower calculator for? It estimates energy cost tied to dust collector fan horsepower.
- What information should I enter? Use fan load, runtime, electricity price, and collectors or lines served.
- What does the result tell me? The result helps compare pressure drop, airflow, motor, and fan upgrade scenarios.
- When is the result only an estimate? It is only an estimate when fan load, airflow, duty cycle, motor efficiency, or utility pricing changes.
