Compressor 1 Phase: How Many Amperes Do You Need?

When it comes to selecting a compressor for your air tools or equipment, one of the most important considerations is the power rating. Specifically, you need to determine the amperage required to run your compressor efficiently and safely. In this article, we will explore the amperage requirements for a 1-phase compressor.

What is a 1-Phase Compressor?

A 1-phase compressor, also known as a single-phase compressor, is a type of compressor that uses a single phase of alternating current (AC) to operate. This type of compressor is commonly used in residential and light commercial applications, where the power supply is limited to a single phase.

Amperage Requirements for a 1-Phase Compressor

The amperage required to run a 1-phase compressor depends on several factors, including the horsepower (HP) rating of the compressor, the voltage rating, and the efficiency of the motor.

Typical Amperage Ratings for 1-Phase Compressors

Here are some typical amperage ratings for 1-phase compressors:

  • 1 HP Compressor: 10-15 Amps at 115 VAC, 5-7 Amps at 230 VAC
  • 2 HP Compressor: 20-25 Amps at 115 VAC, 10-12 Amps at 230 VAC
  • 3 HP Compressor: 30-35 Amps at 115 VAC, 15-18 Amps at 230 VAC
  • 5 HP Compressor: 50-60 Amps at 115 VAC, 25-30 Amps at 230 VAC

Calculating Amperage Requirements

To calculate the amperage requirements for your specific compressor, you can use the following formula:

Amperage (A) = Horsepower (HP) x Voltage (V) / Efficiency (η)

For example, if you have a 2 HP compressor with a voltage rating of 115 VAC and an efficiency rating of 0.8, the amperage requirement would be:

Amperage (A) = 2 HP x 115 VAC / 0.8 = 23.75 Amps


In conclusion, the amperage requirement for a 1-phase compressor depends on several factors, including the horsepower rating, voltage rating, and efficiency of the motor. By understanding the typical amperage ratings for different horsepower ratings and calculating the amperage requirement using the formula above, you can ensure that you select a compressor that meets your power requirements and operates safely and efficiently.
