Compressor Power Consumption Calculator

What is Compressor Power Consumption?

Compressor power consumption refers to the amount of electrical energy that a compressor consumes while operating. This is an important factor to consider when choosing a compressor for your industrial or commercial application. By calculating the power consumption of a compressor, you can determine its energy efficiency and make informed decisions about its usage.

Why is Compressor Power Consumption Important?

Compressor power consumption is important for several reasons:

  1. Energy Efficiency: Compressors can consume a significant amount of energy, and inefficient compressors can lead to high electricity bills. By calculating power consumption, you can identify energy-efficient compressors that can help reduce your energy costs.
  2. Sustainability: In today’s environmentally conscious world, reducing energy consumption is crucial. By choosing a compressor with low power consumption, you can minimize your carbon footprint and contribute to a greener future.
  3. Equipment Sizing: Calculating power consumption also helps in determining the appropriate size of the compressor for your specific application. Undersized compressors may not meet your air demand, while oversized compressors can lead to unnecessary energy wastage.

How to Calculate Compressor Power Consumption?

Calculating compressor power consumption involves the following steps:

  1. Gather Data: Start by gathering the necessary data, including the compressor’s motor power rating (in horsepower or kilowatts) and the duration of operation (in hours).
  2. Convert Units: If necessary, convert the motor power rating to the same unit (either horsepower or kilowatts).
  3. Calculate Power Consumption: Multiply the motor power rating by the duration of operation. This will give you the total power consumption of the compressor during that period.
  4. Consider Efficiency: Keep in mind that the actual power consumption may be higher due to factors like motor inefficiency or energy losses in the system. It is recommended to add a safety margin to your calculated power consumption.


Compressor power consumption is a crucial factor to consider when selecting a compressor for your application. By calculating power consumption, you can make informed decisions about energy efficiency, sustainability, and equipment sizing. Remember to gather accurate data and consider efficiency factors while performing the calculations. Choosing a compressor with low power consumption can lead to cost savings, reduced environmental impact, and optimized performance.
