Regenerative Blower vs. Side Channel Blower: Selection Guide

What are Blowers?

Industry uses regenerative blowers and side channel blowers for blowing air/gas into multiple applications. These are used in different sectors and assist in many tasks. If you are in the need of a blower for your work, then it is very beneficial to know about the differences between these two types and which one suits what you require. In this guide, we will break down everything you need to know about regenerative blowers and side channel blowers in the simplest way possible!

Regenerative Blower

An alternative name for a regenerative blower is ring side channel blower Or possibly vortex blower. This type of blower causes very fast rotation to do the work. The act of spinning the impeller at high speed results in a vortex (whirlpool) effect. This creates a pull, whereby air/gas is drawn into the machine through an intake port and out through an outlet port. Regenerative blowers are quiet due to the fact that no parts come into contact with one another, which makes them ideal for places like hospitals or food factories where noise must be kept low.

Side Channel Blower

On the other side, it is also called vacuum pump or air blower which means a side channel blower. A blower of this sort operates from a spinning blade in a side channel. These blades spin to create a pressure differential across the inlet and outlet ports. The difference in pressure generates the pull to draw in air or gas into the blower and get it out. Side channel blowers are great, but sides tend to be noisier than regenerative blowers as some components can touch and may move.

Differences Between Blowers

Regenerative and side channel blowers may appear nearly identical upon initial inspection, but there are a few attributes you will want to take into consideration when selecting one.

Noise: This is one of the most important differences as they are somewhat loud. Generally speaking, regenerative blowers are significantly quieter than side channel blowers. Due to the non-contacting nature of the components inside a regenerative blower they have lower noise levels. This aspect of them makes these engines more suitable for places where noise reduction is a top priority, including medical fields and food production zones.

Electricity Consumption — Yet another major distinction is the electricity drawn up by every Ring blower. Regenerative blowers normally consume lesser energy as compared to side channel blowers. They are also more efficient as they have no parts to rub against each other, so less energy is wasted. As a result, regenerative blowers can be an ideal choice for any company looking to reduce energy costs or with sustainable values.

Choosing the Right Blower

Obviously when you are trying to decide which blower to choose there are important factors that you need to keep in mind:

Flow Rate: This is the volume of air that can be displaced by the blower. Be sure to check the flow rate if you require a great deal of air!

Pressure: It refers to the intensity with which you want the air to come out of the blower. For some work—as with tamping soil or snow—one needs to exert more pressure.

Energy consumption: Consider how much power the blower does require to function. Long-term: Less energy usage = More savings.

Noise: Think about how noisy the blower will be when it is in operation. If it needs to be silent, that matters.

Hot or Cold: Ensure the blower will operate properly in the temperatures you require, hot and/or cold.

If you require a high capacity and strong regenerative blower, look no further than a regenerative blower. These blowers can only be used to transport items through the most airflow, or lift heavier goods or use in a facility for wastewater treatment purposes.

Contrary, if you need a low-power and low-noise blower then the side channel blower could be suitable to such purposes. Side channel blowers are ideal for air knives to cut a material or shape it, packaging machines to wrap products and vacuum packaging for keeping food fresh.

Conclusion

And in summary, the type of Industrial blower you go for – regenerative or side channel – really comes down to your particular requirements and objectives. A regenerative blower is probably your only option if you want a quiet, efficient blower. However, if your application requires high flow capacity and high pressure then a side channel blower is the answer.
