Given the availability of a large variety of air blower products, it can be challenging to determine which equipment is most suitable for your application. Therefore, it is imperative to distinguish the difference between side channel blowers and other kinds of air technology equipment. To begin, let’s try and understand what a side channel blower is.


What is a side channel blower?
A side channel blower transports air using high-speed rotating impellers, transferring the accumulating kinetic energy through a tight passage and converting it into pressure with each rotation. The rotating impellers generate a series of vortexes, forcing the air to advance in a spiral motion, continuously compressing the air to build pressure from the moment it enters the inlet to the time of leaving the outlet.

It is also important to note there are many names for a side channel blower. This is especially common in the various global regions Goorui operates in.

The units can be referred to as:
Side channel blower
Vacuum pump
Regenerative blower (Regen blower)
Ring blower
Vortex blower
Blower fan

There are many factors that we consider when selecting a side channel blower due to the different variations for different applications. Some of the questions that we must consider are:
1. Do you require a vacuum form or pressure form?
2. Will it be high or low vacuum/pressure?
3. Do you require high or low airflow?
4. Are you looking for a single-stage or two-stage blower unit?

A good place to start to determine the optimal working point is by using Goorui’s performance graph. But of course, our technical team is available to work through your side channel blower needs and determine a suitable setup to overcome your challenges.
