Stationary Air Compressors

Air Compressors

Industrial Air Compressors It’s all about the heart of every compressed air system: the air compressor. Most information in this section will be about oil-injected rotary screw air compressors.  Oil-injected rotary screw air compressors are the workhorse of many industries. They supply a steady flow of compressed air 24/7. How oil-injected rotary screw air compressors …

About the pressure switch on your air compressor

Pressure switches are found on many different types and sizes of air compressors. From the smallest reciprocating compressor, to the biggest rotary screw compressor… they know when to stop and start (or load and unload) because of the pressure switch. On new and bigger machines, the good old pressure switch is replaced by a pressure …

The air compressor inlet filter: more important than you think

For today’s post in the ‘part of the day’  series, I want to talk about the inlet filter of your rotary screw air compressor. The air compressor inlet filter protects your compressor from outside dust and dirt. This is important, because all the dust that is sucked in by the air compressor eventually ends up …

[video] Rotary vane compressors – a better alternative to rotary screw compressors?

The rotary vane compressor is little known to the general public, but why? I must admit, I don’t have any pages about rotary vane compressors on my website (yet!), so I am guilty as well 🙂 Some time ago I received an email from Andy Jones, general manager of Mattei Compressors Ltd in the United …

How the overload relay (‘thermal block’) protects your air compressor

In this second post in the ‘part of the day’ series, I will discus an important part that is found on almost all but the smallest (<2 kW) compressors: the overload relay. The overload relay is also often called the ‘thermal block’ or ‘thermal relay’. This part protects your compressor from self-destructing when things go …

How the scavenge line keeps your compressed air oil free

This is the first post in the ‘part of the day’ series. In each post I will discuss another air compressor part. I will explain what they do, how they work and how to troubleshoot when there are problems. The part of today is: the scavenge line. The scavenge line is found on all bigger …

[video] Ingersoll Rand – double stage rotary screw air-end, how they work

Here’s a nice video how the double stage rotary screw air-ends of Ingersoll Rand works. In this compressor element, there are two sets of rotary screws: 2 big ones (low pressure stage) and two smaller ones (high pressure stage). It is said that: They provide increased reliability by reducing the compression ratio required for each …
