Welcome to the biggest online source of free information about industrial air compressors and compressed air.

Learn all bout air compressors, air compressor parts and everything compressed air related (dryers, filters, maintenance, etc).

If you are looking to buy an air compressor and looking for buying help, be sure to check out my air compressor buying section.

If your air compressor is having problems, read these Compressed Air 101 pages for general information, and be sure to ask your questions/problem in the Air Compressor Troubleshooting pages.

I have divided the information in this section into 4 main blocks:

* Air compressor types

An overview of the different kinds of air compressors. I mainly focus here on rotary screw compressors, reciprocating compressors and scroll compressors.

* Air compressor Parts

An overview of the main parts of the air compressors. I will discuss here the function and use of parts like pressure switches, oil filters, check valves, unloader valves, and a lot more.

* Compressor Uses

Some pages about different compressor uses: paintball compressors, dental compressors, scuba diving compressors, portable air compressors, and more..

* Compressed Air Systems and components

This part is not focused on the air compressor itself, but focuses on everything that comes after it: compressed air piping, air dryers, compressed air filters, and more..

Use the menu in the right column to navigate all the different topics. Some topics span multiple pages or are dived into sub-topics, so be sure to check them all out.
