Your compressor is overheating

There can be 3 main, completely different, reasons for an overheating compressor. Do you know how to pinpoint the problem?

pressure-64.png

Low pressure

Having low pressure at your compressed air consumers? Is it the compressor, the piping system, the filters… or something else?

The guide includes troubleshooting flowcharts for every problem and compressor part.

It will help you to easily pinpoint the exact cause of the problem. Simply follow the flowchart, answer a simple question and find the cause of the problem.

It’s like I’m standing there with you… You just have to follow the flowchart by answering simple question like ‘was the oil changed recently?’, or ‘is air blowing out of valve x?’.

Of course, for every compressor problem I discuss I also include background information, a detailed explanation of the cause of the problem and what to do to fix it.

For every part I explain in detail how it works, how to check if it works correctly, and what to do if the part doesn’t work.

Who Am I And Why Did I Write This Troubleshooting Guide?

me-xa-186-compressor.png

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

How did I learn all this stuff? My whole professional life I have worked with air compressors. I worked for the biggest air compressor manufacturer in the world as an engineer and product specialist. And I worked in various engineering jobs where air compressors were used or were vital for the correct operation.

Which simply means: I know everything about air compressors.

Plus, I love air compressors and take any chance I get to learn more about them!


I remember when I was a compressor specialist for one of the biggest air compressor brands out there. I was on standby duty and was called at 4 am in the morning to a printing business that had compressor problems: their compressor was down and their whole printing line grinded to a halt.

It took me 1.5 hours to get there. I fixed this compressor in a few minutes. But…

… this company had lost 2 hours of production that the day-shift had to make-up for, and they had to pay my boss at a 200% rate!

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

And I know that not everyone has access to reliable, quick, professional support from a compressor maintenance company.

Maintenance companies can take hours, or even days, before visiting you with your small compressor and your small (in their eyes) problem.… 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 are simply not available within a few hundred miles.

What you will get:

This is a 146 page information-packed troubleshooting guide for oil-injected rotary screw air compressors.

My guide will show you how to troubleshoot the most common air compressor problems.

It covers all topics regarding oil-injected rotary screw air compressors.

The complete workings of the whole air compressor is explained. The oil system, the air system, the control system, and all the parts are explained in depth, with pictures and diagrams, and with troubleshooting flowcharts.

But if you don't care about that, and just want to fix your compressor ASAP, that's possible too! Just follow the troubleshooting flowcharts.

To-the-point and plain English

I’m known for my to-the-point writing style, people appreciate is because they want to fix their compressor, not read about it.

Believe me, I always stay on-topic, to-the-point and I explain everything in clear, plain English language that anybody can understand.

The cost of compressor downtime

I worked in a densely populated, industrial part of the world and I was on-site within hours when a compressor went down.

But, the company I worked for charges accordingly. A complaint I often received back then…

In fact, my hourly rate was higher than the cost of this complete guide!!!

An average compressor service technician will cost you at least $60 per hour…bare minimum. Plus they need time and petrol to drive to your site while valuable work time is being lost.

How much does it cost you to lose 2 to 4 hours…or possibly even a whole day of work?

One problem will cost you at least $300 if you don’t know how to fix it. And this is in addition to the hours of downtime while waiting for the man to arrive.

Now you can have this easy-to-use guide, bonus printable flowcharts, all for the cost of significantly less than one service call.

And, you will have your compressor up and running again in no time!
