Compressors are electric or gas-powered air pumps. They come in a variety of shapes and sizes, from small, portable units to large, stationary ones. The size of the compressor you need depends on the job you need it to do.

For example, if you need to blow out your sprinklers, you will need a compressor that can generate enough air pressure to push the water out of the system. The amount of air pressure you need is measured in pounds per square inch (psi). Most compressors can generate between 90 and 120 psi.

To calculate the size of the compressor you need, first determine the volume of your sprinkler system. This is the total number of gallons of water it can hold. For example, if your system can hold 200 gallons of water, you will need a compressor that can generate at least 200 psi.

You may also need to consider the CFM, or cubic feet per minute, rating of the compressor. This is a measure of how much air the compressor can deliver in a given amount of time. For example, if your system needs 200 gallons of air per minute to work properly, you will need a compressor with a CFM rating of 200 or higher.

Once you have determined the size of the compressor you need, be sure to select one that is properly rated for use in your area. In most cases, this will be an electrically powered unit. However, if you live in an area with frequent power outages, you may want to consider a gas-powered unit as well.

How to determine the size of your compressor

Whether you’re a first-time buyer or simply need to upgrade, this task may feel daunting. Sizing a compressor requires only a few minutes and basic understanding of CFM (Cubic Feet per Minute). CFM is a unit of measurement that determines the volume of air that a compressor can output in a single minute. In order to calculate the CFM, you’ll need to know the compressor’s PSI (Pounds per Square Inch).

Look in your user manual

The user manual for your specific model of compressor should have all the information you need to know about how much air it can produce per minute. This will tell you the CFM, or cubic feet per minute, ratings for your compressor at various PSI, or pounds per square inch, readings.

Check the CFM requirements

Compressors are rated by the volume of air they can deliver, expressed in cubic feet per minute (CFM). To calculate the CFM you need, first determine the size of youripple system. Then add up the CFM requirements for each component in your system.

For example, a standard 1/2-inch impact wrench requires 6 CFM, and a 3/8-inch impact wrench needs 4 CFM. If you have both sizes of impact wrenches, you would need 10 CFM.

Consider the PSI requirements

compressed air by the pound per square inch or CFM (cubic feet per minute). Standard home air compressors range in size from 1 to 5 horsepower. The average size used in most auto repair shops is around 2 or 3 horsepower. Once you know the CFM and PSI requirements of the job, you can narrow your choices down to a few compressor types.

The first thing you’ll need to know is the PSI. Most air compressors have a Continuous Duty rating or an Intermittent Duty rating. The Continuous Duty rating is the maximum amount of pressure the compressor can produce while being used constantly. The Intermittent Duty rating is usually about 20 percent less than the Continuous Duty rating and is what you’ll want to look for when selecting an air compressor for intermittent use, like blowing out your sprinklers.

When looking at air compressors, you’ll want to find one that has a PSI (pounds per square inch) that meets or exceeds the maximum PSI required by your tools or equipment. In general, most pneumatic tools require between 90 and 120 PSI. To be safe, look for an air compressor with a PSI that meets or exceeds the tool’s requirements.

Factors to keep in mind when choosing a compressor

When choosing a compressor to blow out your sprinklers, you’ll need to keep a few factors in mind. The size of your compressor will depend on the size of your sprinkler system. If you have a large system, you’ll need a larger compressor. You’ll also need to consider how often you’ll be using your compressor. If you only need to use it once a year, a small compressor will suffice. However, if you plan on using it more frequently, you’ll need a larger compressor.

Tank size

The size of the tank is an important determining factor when choosing a compressor. A larger tank will be able to hold more air, meaning that the compressor will not have to work as hard and will therefore last longer. If you plan on using your compressor for long periods of time or for large projects, a larger tank is a better choice. Smaller tanks are less expensive and can be a good option for shorter-term use or for smaller projects.


Horsepower is one of the key factors to keep in mind when choosing a compressor. The amount of power you need will depend on the job you’re doing. If you’re just blowing out your sprinklers, a small, household compressor should suffice. But if you’re working on a construction site or doing other heavy-duty work, you’ll need something with more power. In general, the more horsepower a compressor has, the more expensive it will be.

Duty cycle

Duty cycle is the percentage of time in a 10-minute period that a compressor can be operated without damaging it. For example, a 100-PSI air compressor with a 60% duty cycle must be turned off for 4 minutes after 6 minutes of use to allow the unit to cool down. This Limits its applications.


Now that you know how to determine the CFM and PSI requirements for your compressor, as well as which size tank is best for you, you’re ready to purchase the perfect model for the job. Be sure to consult with an experienced contractor or sprinkle system professional to ensure that you’re getting the most out of your purchase.
