A surprising number of industries rely on roots blowers to efficiently provide continuous flows of air or gas. Just a few examples include pneumatic systems, combustion systems, wastewater, and fish farming. The blowers are one of the most popular pieces of equipment here. They can provide the ideal balance of precision, performance, and versatility. However, they can also be noisy. You may need a bespoke inline silencer to tackle the problem.
How do they work?
The main reason roots blowers are so essential is they can provide a really consistent flow of gas or air. At the same time, they offer low pulsation levels to maintain the pressure. It ensures efficiency and reliability for all kinds of applications.
Central to the amazing performance is the design and precise engineering. What you have is a casing with two rotating lobes inside. They turn in opposite directions. The rotation of the first lobe pulls whatever gas you are working with in through the inlet. It stops in the gap between the lobes before scattering to the casing. The second lobe then sends it to the outlet.
An important detail here is the lobes don’t touch the casing. They never come in contact with each other either. This ensures the rotation is consistent. Additionally, it massively reduces wear, meaning you don’t need to replace parts as frequently. It can reduce noise too.
Choosing the right type
As we said, generally roots blowers have two lobes. This is the classic design, simple and reliable. However, there are also models with three lobes. The extra lobe provides two key benefits; it reduces the pulsation even further and it makes the blower quieter. You may still need an inline silencer though.
Some applications will need a very specific type of blower able to achieve a high vacuum. These high vacuum blowers provide a lower flow rate in order to achieve the required pressure.
If you’re trying to decide what type of roots blower to choose, there are a number of key factors to look at. As with most things, the starting point is always to make sure you understand the application, especially the volume of gas you require. Think about the operating conditions and environment too.
It’s also vital to think about the costs. Firstly, look at energy efficiency. Blowers can be incredibly efficient to save energy and reduce daily running bills. Secondly, think about the maintenance side. Your goal should be to choose a blower that has a long service life with infrequent repairs or replacements.
Talk to us if you need an inline silencer
There is one final thing to think about before you commit to any kind of roots blower. You should have a good look at the noise. Businesses have an obligation to limit noise exposure and protect staff. There are also environmental rules. So, you need to choose blowers that won’t cause problems. If noise is an issue, you must consider solutions like silencers.
