About Me:
My name is Cas and I am crazy about air compressors!
I started this website to help people learn more about air compressors and compressed air. I’ve worked in the compressed air business for years and saw that many people throw money away every day:

That’s why I’ve decided to build this site: let everyone know about the wonderful world of compressed air, and how to do it right!
