What Does the HP of an Air Compressor Mean?

When choosing an air compressor, a bit of research can give you a better understanding of what you could buy. The HP measurement is a common power measurement used in air compressors to identify the power of the motor.

Identification

On an air compressor, HP stands for horsepower. You can find out your air compressor's horsepower by checking the box or manual for power information.

Function

The horsepower rating on an air compressor is a measure of the power of the compressor's motor.

Size

Most commercially available air compressors advertise horsepower ranging from 2.5 to 10 HP. Horsepower is a measurement equal to 746 watts. If you are running seven 100-watt light bulbs, you are using slightly less than 1 HP.

Misconceptions

Though horsepower does affect the power of an air compressor, it is not an exact measurement of the potential output of the compressor, since motor efficiency affects the compressor's output. A lower horsepower motor could outperform a less efficient, higher horsepower motor.

Considerations

An HP compressor can also refer to a high pressure compressor. High pressure air compressors have a higher air pressure range than ordinary compressors and are often used with nail or paint gun attachments.
