Air Consumption Cost Calculator

How to Use This Calculator

1. Enter the air flow rate in CFM (Cubic Feet per Minute).
2. Input the operating air pressure in PSI (Pounds per Square Inch).
3. Provide the cost of electricity per kWh ($/kWh).
4. Set the compressor motor efficiency (as a percentage).
5. Click the "Calculate" button to see the estimated daily, monthly, and annual air consumption costs.

Understanding the Formula

The calculator uses the following formula to estimate air consumption costs:

Cost = (Flow × Pressure × 1.8 × 24 × 0.746 × (1/efficiency)) × Electricity Cost

Where:

• Flow - The volume of air consumed per minute
• Pressure - The air pressure at which the compressor operates
• 1.8 - Conversion factor from PSI to bar (1 PSI = 0.06894757 bar)
• 24 - Number of hours in a day
• 0.746 - Conversion factor from horsepower to kilowatts (1 hp = 0.746 kW)
• Efficiency - The percentage of electrical energy converted to compressed air energy
• Electricity Cost - The cost of electrical energy per kilowatt-hour

Practical Applications

This calculator helps you:

• Estimate the operating costs of compressed air systems
• Compare different compressor configurations
• Identify opportunities for energy savings
• Make informed decisions about equipment upgrades

Important Notes

This calculator provides an estimate based on theoretical calculations. Actual costs may vary due to factors such as:

• Compressor type and age
• System leaks
• Environmental conditions
• Operational patterns
