Air compressors are an essential tool for many industries, from construction to automotive repair. They can be used for a variety of tasks, such as powering pneumatic tools, inflating tires, and even painting. However, with so many different types and models available on the market, it can be challenging to know what to look for when buying an air compressor. In this article, we will discuss some of the essential factors to consider when purchasing an air compressor.
1. Size and Portability
One of the first things to consider when buying an air compressor is its size and portability. If you need to move your compressor frequently, a portable model with wheels and a handle is a good option. However, if you plan to use your compressor in a fixed location, a larger stationary model may be more suitable. Additionally, larger compressors typically have a higher air volume and pressure capacity, making them better suited for heavy-duty tasks.
2. Power Source
Air compressors can be powered by electricity, gas, or diesel. Electric compressors are typically quieter, lighter, and easier to maintain, but they may not be powerful enough for some tasks. Gas-powered compressors are more robust and better suited for outdoor use, but they require more maintenance. Diesel-powered compressors are the most powerful option but are also the most expensive.
3. Tank Size
The size of the compressor’s tank determines how much compressed air it can hold and how long it can run before needing to refill. A larger tank size is beneficial for tasks that require a continuous supply of compressed air, such as sandblasting or spray painting. However, larger tanks also mean a heavier and less portable compressor.
4. CFM and PSI
The CFM (cubic feet per minute) and PSI (pounds per square inch) ratings of an air compressor determine its air volume and pressure capacity. CFM indicates how much air the compressor can produce, while PSI indicates the maximum pressure it can deliver. It’s essential to consider both ratings when purchasing a compressor, as some tools require a higher CFM or PSI than others.
5. Oil-Free or Oil-Lubricated
Air compressors can be either oil-free or oil-lubricated. Oil-free compressors are low-maintenance and ideal for tasks that require clean air, such as painting or medical equipment. However, they may not last as long as oil-lubricated models. Oil-lubricated compressors require more maintenance but are more durable and better suited for heavy-duty tasks.
6. Noise Level
The noise level of an air compressor can be a significant factor, especially if you plan to use it in a residential area or shared workspace. Electric compressors are typically quieter than gas or diesel-powered models, but it’s still essential to check the decibel rating before purchasing.
In conclusion, buying an air compressor requires careful consideration of several factors, including size, power source, tank size, CFM and PSI ratings, oil-free or oil-lubricated, and noise level. By taking these factors into account, you can choose the right air compressor for your needs and get the most out of your investment.

FAQs for What Do I Need To Know When Buying An Air Compressor?
What factors should I consider when buying an air compressor?
There are several factors to consider when buying an air compressor, including the type of compressor, the horsepower, the tank size, the CFM (cubic feet per minute) rating, and the voltage requirements. You should also consider the type of tools you will be using with the compressor and the environment in which you will be using it.
What type of air compressor should I buy?
The type of air compressor you should buy depends on your specific needs. If you need a compressor for light-duty tasks, a pancake or hot dog compressor may be sufficient. For heavier-duty tasks, a vertical or horizontal stationary compressor may be necessary. If you need a compressor for on-the-go tasks, a portable compressor is a good option.
What maintenance is required for an air compressor?
Regular maintenance is important for keeping your air compressor in good working order. This includes checking and changing the oil, cleaning or replacing the air filter, draining the tank of moisture, and checking for leaks. It is also important to follow the manufacturer’s guidelines for maintenance and to use the appropriate oil and filters.
What safety precautions should I take when using an air compressor?
It is important to follow safety precautions when using an air compressor to avoid injuries and accidents. This includes wearing protective gear, such as eye and ear protection, and following proper procedures for starting and stopping the compressor. You should also be aware of the risks of over-inflating tires or using the compressor in wet or damp conditions.
