If you’re planning to run a compressor with a generator, the type, and size of your compressor are vital to know. It’s essential to understand the amount of power your compressor needs, or you may end up with a generator that’s too weak or too powerful.

We’ll explain the different compressor types and power requirements to help you determine what size generator you need.

Description Of Compressor Types And Their Power Needs

There are three main types of compressors: reciprocating, rotary screw, and centrifugal. Each compressor type has different power requirements, so let’s take a brief look at them:

Reciprocating Compressors

Reciprocating compressors are the most common type of compressors. They come in two styles – single-stage and two-stage, with the two-stage compressor being more powerful. These compressors need a large amount of power to start and generally require up to six times their running wattage to start up.

  • Single-stage reciprocating compressors: Require a starting wattage of 1.5 to 2 times their running wattage.
  • Two-stage reciprocating compressors: Require a starting wattage of 3 to 5 times their running wattage.

Rotary Screw Compressors

Rotary screw compressors are commonly used for industrial applications and are known for their reliability and consistency. They’re more efficient and have a longer lifespan than compressors that use reciprocating technology. These compressors need less power to start up than their reciprocating counterparts.

  • Rotary screw compressors: Require a starting wattage of 1.5 to 2 times their running wattage.

Centrifugal Compressors

Centrifugal compressors are the least common type of compressors and are generally used for industrial applications. They’re known for their high efficiency and power output. These compressors require a lot of power to start up but use less power during their operation.

  • Centrifugal compressors: Require a starting wattage of 6 to 8 times their running wattage.

Calculation Of Compressor Power Requirements

Now that you understand the power requirements of different compressor types, you can calculate how much power you need for your compressor.

To calculate the power requirements, add the starting wattage and running wattage of your compressor type.

For example, if you have a 5 horsepower, single-stage reciprocating compressor:

  • Multiply the motor horsepower by 1,000 to get the compressor’s watts. In this example, 5 horsepower x 1,000 = 5,000 watts.
  • Add the starting wattage and running wattage of your compressor type. If your single-stage reciprocating compressor requires 1.5 times its running wattage to start up, add 5,000 watts (running wattage) x 1.5 (starting wattage multiplier) = 7,500 watts required to start up.

Calculating your compressor power requirements will help you determine the size of the generator you need to run your compressor efficiently.

Understanding your compressor and its power requirements is critical when selecting a suitable generator. Make sure you take the time to calculate your compressor power requirements accurately to ensure you purchase or rent the right generator for the job.
