Your compressor is down. You want it fixed. Fast.

Many people don't realize how important compressed air is for their factory, until their compressor breaks down.

Compressor problems can quickly result in hours (if not days) of production downtime and a loss of thousands of dollars per hour.

Even 'small' problems like a water or oil in the air can have tremendous consequences when they contaminate your products or ruin your machines.

There is nobody there to help you?

Not everyone has access to reliable, quick, professional support from a compressor company.

They can take hours, or even days, before visiting you. While you are stressing out over lost production hours, deadlines, angry customers, and things like that.

In other parts of the world, a good service technician is simply not available within a few hundred miles.

Frequently Asked Questions

Here are some questions and objections I have received about my troubleshooting guide.

Q: I have a ... *insert make and model here* - Will this guide work for my compressor?

A: Yes! This guide works for all oil-injected rotary screw air compressors.

Atlas Copco, Ingersoll Rand, Kaeser, Compair, Chicago Pneumatic, Sullair, Quincy and many more!

All oil-injected rotary screw compressors have the same working principle, same parts and same problems. Yes, some details will vary but in general - they are all alike.

For this reason, my guide works for ALL oil-injected rotary screw air compressor.

Q: I have two left hands - I'm really not sure I can do this?

A: While some parctical engineering experience is always helpful - you don't need any special knowledge or experience with air compressors to use this guide.

The guide explains all in details and includes troubleshooting flowcharts for every part and every problem. It’s almost like I’m there holding your hand.

Q: Will this work for my diesel- / portable air compressor?

A: Most of the time, yes.

The compressor system of a diesel- /portable air compressor is 95% the same as for a stationary electric compressor. You will be able to use most of the information in this guide to fix your problem.

Q: The guide is too expensive for me - can I get a discount? Can I get it for free, pretty pleaaassssee?

A: Sorry, I don't give away this guide for free or give individual discounts.

An air compressors costs thousand to tens of thousands of dollars. Yearly energy costs are about the same.

A factory without compressed air is like a car without petrol. Downtime will cost you hours or days of lost production. Bad quality air will results in hundreds of products that don't pass quality inspection.

The investment in this troubleshooting guide is tiny compared to the amount of knowledge and practical guidance it gives you.

Q: I want to use your guide to learn about rotary screw air compressors in general. Is it suitable for that?

A: Yes, very much.

Although the guide is primarily setup for troubleshooting help.. It will definitely give you a full understanding of how oil-injected rotary screw compressors work.

The guide starts with an explanation of the air- oil- and control-system of the compressor. It includes a complete explanation of all parts in a rotary screw air compressor - what every part does, how it works, how to check them, and how to troubleshoot them.

It then goes into troubleshooting specific problems like overheating, oil-in-air, low pressure, etc.

I know at least one company who use it as training guide for their new technicians. And a few companies (compressor sales/maintenance) ordered multiple copies for their technicians.

Here's what some happy customers have to say about his guide:

Great Job on the Book!!

I just bought you book (Hard copy and download) on rotary compressors. It is fantastic!!!

I did a fast cursory read of the download, and it was great. This is the way all Tech book should be written. It is straight forward, no nonsense with great insight.

I have been doing industrial millwright work for over 45 years. Great Job – I signed up for your upcoming work.

I am very happy with your manual. It's great for troubleshooting any type of machine. Your manual helped me figure out what was wrong with a machine that others had given up on.


I was desperate enough to try something that will help the factory from being down for long.

As a result of buying the guide, we got access to you (Cas), which basically is what helped us troubleshoot the problem. We tried what you told us in an email and it worked. Thank you!

For individuals, it may be a little expensive, for us it is worth it.

Just received your book and it is fantastic. I operate 25 diesel powered compressors in twenty countries ranging from 375 to 1100 CFM. Thanks for writing it!

Thank you for the in depth analysis of our issue and the easy to follow step.

You have a great talent for explaining in easy to follow language...thanks

I didn't have any issues with our compressor... I mainly bought it as a learning guide as I am inexperienced with compressors.

I looked over the book and liked the troubleshooting flow charts. I believe I will be able to use them in the future.

Overall I thought the guide was good and worth the money.


I purchased a copy of your air compressor trouble shooting book. It is excellent.

You have put a lot of home work into this whole program and it is of great benefit. Many thanks

Who am I - and WHY did I write this Troubleshooting Guide?

I like to take a picture whenever I spot an air compressor :)

My name is Cas and I am crazy about air compressors!

My whole professional life I have worked with air compressors. Before starting this website, I worked for the biggest air compressor manufacturer in the world as an engineer and product specialist.

I receive (and answer) troubleshooting questions daily, from all over the world, so I know what the common problems are out there.

Why this Troubleshooting Guide?

I see time and time again how small easy-to-fix compressor problems escalate to thousands of dollars of repair costs and production downtime.

I want to save you from making the same mistakes!

(those maintenance managers I met always had a nervous energy about them because their boss was breathing down their neck and their whole factory was down).

Fact is, most problems were easy to fix - if you just know the basics of air compressor troubleshooting.

That's why I decided to write this troubleshooting guide!

But don't take my word for it!
