Air Compressor Buyer’s Guide:

In the above list, we have reviewed some of the best air compressors for you to use. But if you are still figuring out which air compressor will be good for you worry not.

Here are some things to consider when buying an air compressor. After all, this is a one time investment and it is recommended to study all available models before settling for the right one. 

What Is PSI in Air Compressor:

PSI basically stands for pounds per square inch.

If an air compressor has a higher PSI then it will quickly refill your tank in a shorter time and it handles work faster and efficiently. But the PSI will act differently when considering the tank size of an air compressor.

What Does CFM Stand For Air Compressor:

CFM means cubic feet per minute.

This is used to describe the rate at which a compressor can fill. CFM varies on the weather as gases change the pressure at different temperatures.

If you are using the compressor to power your equipment or tools then go for higher CFM. 

Oil vs Oilless Air Compressor:

The Oil-Free Air Compressor is great as they are quite durable and do not require daily maintenance. And they are a lot more cost-effective because you won’t have to buy oil or dispose of it at all. 

Whereas, the Oil air compressors require more maintenance than oil-free because the oil has to be changed from time to time depending upon how much is consumed.

However, oil-free compressors don’t last as long as oil air compressors.

That’s why oil-less is great for home use or where your usage is minimum and oil air compressors are used for industrial purposes and long working hours.

Oil air compressors are much less noisy than oil-free compressors.

When choosing between oil or oil-free compressor keep in mind the amount of usage you want to do and weigh the pros and cons of it. 

Tank size:

Air compressor features different tank sizes from 1 gallon to 80 gallons or more. The bigger tank is great if you want your air tools to run steadily for a long time.

As it will be able to quickly produce as much air as the tool needs. 

Electric vs Gas Air Compressors:

Another factor to consider when buying a compressor is whether it should be Electric or Gas Powered.

Don’t stress on it too much as both of these will do their job efficiently and there are no major differences in terms of performance.

The gas air compressor is great for those situations where there is no electricity or the location where you need to use it is far away.

Also, they are very expensive and they should not be used indoors as that gas compressors produce fumes which are toxic and the Gasoline used in the compressor is highly flammable so you should do proper maintenance of it.

Whereas, the air electric air compressors are more common and they provide much quieter operation than gas compressors.

They are generally cheaper than the gas compressor and are easier to use. If the job site or the place where it has a power outlet then an electric compressor is a good choice. But the main downside of the electric compressor is that you can’t use it without an extension cord.

Which compressor is right for you?

To choose an Air Compressor you need to ask yourself How much power do I need, What kind of jobs can I do with it, Which will be suitable for me gas or electric-powered, and finally What is my budget. By doing this you will easily figure out which air compressor is best for you.
