The average horsepower rating for an air compressor falls between 1.5 and 6.5 HP, although large stationary models can feature up to 15 HP. It’s also key to consider your compressor’s power source since it impacts HP ratings. For example, an electric model can do the work of a 10 HP gas- or diesel-powered air compressor at only 5 HP.
What is the output of an air compressor?
CFM measures the volume of air, in cubic feet, for each minute it moves. In the case of an air compressor, CFM indicates how much air can move per minute. For example, an air compressor's output rated for 30 CFM means 30 cubic feet of air is flowing per minute.
How much power does an air compressor pull?
Heavy-duty compressors operate on 220-volt current and require special wiring and outlets. A 110-volt compressor drawing 15 amps uses 1,650 watts (110 volts x 15 amps), while a 220-volt compressor drawing 15 amps consumes 3,300 watts (220 volts x 15 amps).
How do I calculate air compressor output?
The way to measure true power is to measure the time it takes to pump the reservoir tank of known volume from a known starting pressure to a known ending pressure. Then you can figure the true CFM from the difference in starting and final pressures, times the volume of the tank, divided by the time it took to pump up.

How much horsepower does an air compressor have?
Air compressors typically have a horsepower rating between 1.5 and 6.5, though some larger, stationary air compressors can have up to 15 HP. If you are using standard electric power outlets, you’ll need an air compressor at 2 HP or less because standard AC cords require lower voltage to function.
Why do you need to run a gas compressor at 10 HP?
This is because a gas engine actually produces power through its own combustion, while electric motors draw their power from an external system.
How Important Are Horsepower Ratings When Shopping for a New Compressor?
A compressor’s horsepower rating is an important measure of what it can do and how well it can do it. Under no circumstances will a 5 HP air compressor be able to do the same job as a 100 HP air compressor. However, it is important to remember that horsepower alone shouldn’t be the only factor you consider. The “best” 5 HP air compressor may not be the right one for you if it doesn’t deliver the CFM or PSIG you require of it.
What is the difference between HP and CFM?
Horsepower (HP), pressure (PSIG) and capacity (CFM) are the three main measurements of what a compressor can do. PSIG is a measure of air pressure. To work properly, most air-powered tools require at least 90 PSIG. CFM refers to the maximum amount of air a compressor can produce at a given pressure level. To run multiple air powered tools at once, a higher CFM rating is required.
What is a CFM?
CFM refers to the maximum amount of air a compressor can produce at a given pressure level. To run multiple air powered tools at once, a higher CFM rating is required. When all other factors are equal, horsepower is a measure of the compressor motor’s efficiency at producing a given level of CFM and PSIG. For example, if a 5 HP air compressor and ...
What is stationary air compressor?
Stationary air compressors are designed to be bolted to a fixed area and wired directly into your electrical circuit. With larger tanks and greater horsepower, stationary air compressors are ideal for workshops and garages. The tank size of your air compressor also determines the scope of work you can accomplish.
Why do you need horsepower ratings for air compressors?
When shopping for a new air compressor, many customers look to its horsepower rating to get a sense of how much power it can provide. The reason for this is understandable — most of us are familiar with horsepower ratings and use them as a factor when buying a car, lawnmower or other equipment.
How many rpm does a compressor motor run?
Also note the operating rpm. Most electric motors found on compressors will operate at approximately 1,725 or 3,400 rpm. The slower rpm units generally hold more value, since they operate more quietly, generate less heat and produce less wear and tear than faster motors.
How to determine compressor rating?
In theory, this specification could be determined by multiplying the cylinder bore by the stroke and revolutions per minute (rpm). However, this formula only calculates displaced cfm. Due to factors such as atmospheric pressure, temperature and friction, compressors actually produce less air than this number implies.
What is the difference between peak and continuous horsepower?
operates at 1.5 horsepower. This is the difference between peak and continuous horsepower. Peak horsepower is the maximum output that a motor can produce. However, the motor only achieves this level during startup when the start windings are engaged.
What does cfm mean in compressor?
Many terms are used to describe air compressor performance. Cubic feet per minute (cfm) measures the volume of air that a compressor delivers. Pounds per square inch (psi) indicates the amount of pressure behind the air. Horsepower represents the power that the engine or motor produces to turn the pump.
What is the service factor of a motor?
The service factor can further predict how a motor will operate under load. This number indicates the percentage of continuous horsepower at which the motor can safely operate. For example, if the service factor is 1.15, the motor can run without issue at 115 percent of its rated continuous horsepower. The higher the service factor, the better the motor is at handling various operating conditions.
What is the standard CFM?
For instance, standard cfm gives the volume of a unit according to certain conditions, such as 14.7 pounds per square inch absolute (PSIA), 60 degrees ambient temperature and zero percent relative humidity. Actual cfm calculates the true output of a compressor at real-world operating conditions.
What happens if an electric motor is underpowered?
