Whether you’re a professional contractor or an avid DIYer, a portable air compressor is an essential tool that you should have in your arsenal. The right air compressor will offer you the flexibility and power to get the job done quickly and efficiently.
But before you purchase your first (or next) portable air compressor, there are a few key considerations that you need to keep in mind. This buyer’s guide will help you understand the features and specs of a portable air compressor so that you can choose the best one for your needs.
1. Compressor Type
Contents
The two primary types of compressors are reciprocating and rotary screw. Reciprocating compressors are the most common type and are well-suited for tasks that require intermittent use. They are often used to power air tools and air nailers. These compressors are generally lightweight, affordable, and easy to use and maintain.
Rotary screw compressors are designed for continuous use and can provide a steady stream of high-pressure air. They are more expensive and require more maintenance than reciprocating compressors, but they are more powerful and efficient. Rotary screw compressors are well-suited for tasks like sandblasting and powering pneumatic machinery.
2. Tank Size
The tank size of a compressor is measured in gallons, and it determines how much air the compressor can store for use. Generally speaking, the larger the tank, the more air pressure it can store and the longer it will be able to run without having to stop and refill.
For light-duty tasks, a compressor tank that is between 1.5 and 3 gallons should be sufficient. If you’re using the compressor for more demanding tasks, you may need one with a larger tank size.
3. CFM and PSI Ratings
The CFM (cubic feet per minute) rating of a compressor indicates the volume of air it can deliver, while the PSI (pounds per square inch) rating indicates the amount of pressure it can generate.
When choosing a compressor, you want to make sure that it can deliver enough air to power the air tools and machinery that you will be using. You should also make sure that the compressor can deliver enough pressure to get the job done.
4. Portability
Portability is an important factor to consider when buying a portable air compressor. You want to make sure that it is easy to move and transport from one job site to another. If the compressor is too heavy, it could be difficult to move or even impossible to lift.
The best way to determine if a compressor is portable is to check the weight and size. A compressor that is light and compact will be easier to move and transport.
5. Noise Level
The noise level of a compressor is also an important factor to consider. Compressors can be quite loud, so you want to make sure that it is not too noisy for your work environment.
You can check the noise level of a compressor by looking at the dB rating. The higher the dB rating, the louder the compressor will be.
Conclusion
A portable air compressor is an essential tool for any professional or DIYer. However, there are a few key considerations that you should keep in mind when choosing one. This buyer’s guide should help you understand the features and specs of a portable air compressor so that you can make an informed decision and pick the perfect compressor for your needs.
