When choosing an air compressor, there are many factors to consider in order to find the best one for you. The following is a guide to help you choose the best air compressor for your needs.
- Size: The size of the compressor is important to consider. You want a compressor that is large enough to handle the job you need it for, but not so large that it is difficult to move or store.
- Type: There are two main types of air compressors: portable and stationary. Portable air compressors are great for those who need to use their compressor in different locations or for small jobs. Stationary air compressors are more powerful and are typically used in workshops or for industrial applications.
- Power: The power of the air compressor is measured in horsepower (hp). The higher the hp, the more powerful the compressor. Choose a compressor with enough power to handle the job you need it for.
- Tank size: The size of the tank is important to consider, especially if you will be using the compressor for tasks that require a lot of air, such as inflating tires. A larger tank will allow you to complete the task without having to stop and wait for the compressor to refill.
- Air flow: The air flow is measured in cubic feet per minute (cfm). The higher the cfm, the more air the compressor can deliver. Choose a compressor with a high cfm if you will be using it for tasks that require a lot of air.
- Pressure: The pressure is measured in pounds per square inch (psi). The higher the psi, the more pressure the compressor can generate. Choose a compressor with a high psi if you will be using it for tasks that require high pressure, such as powering air tools.
- Noise level: The noise level is important to consider if you will be using the compressor in a location where noise is a concern, such as in a residential area. Choose a compressor with a low noise level if noise is a concern.
These are just a few of the factors to consider when choosing an air compressor. Take the time to compare the features of different models to find the best one for your needs.
The different types of air compressors
There are three main types of air compressors: positive displacement, dynamic, and rotary screw.
- Positive displacement compressors work by trapping a volume of air in a chamber and then reducing the volume of the chamber. This type of compressor is often used for applications that require a very high air pressure, such as in scuba diving tanks.
- Dynamic compressors work by using blades or impellers to draw air into the chamber and then compress it. This type of compressor is often used in applications where a high air flow is required, such as in air conditioners.
- Rotary screw compressors work by using two rotating screws to draw air into the chamber and then compress it. This type of compressor is often used in applications where a high air flow is required, such as in air conditioners.
