[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 stage resulting in lower bearing thrust loads and increased airend life.

Sounds logical, but they probably come with a big price tag, and they have more moving parts, which can be a disadvantage.

 

My name is Cas. I’ve worked in the compressed air business for years and saw the same mistakes over and over again. This website is my answer. The best way to get started is to download my free e-book “Hidden Compressor Problems”.
