Roots blowers are a generic term used for positive displacement rotary air blowers. These are one of the most important parts of any manufacturing and processing industry.
It is most helpful in handling bulk material and dust collection processes especially in these systems:
Read on to learn more about how choosing the right roots blower can help increase production and process efficiency in the workplace.
With different brands of roots blowers sold in the market today, how do you find the right roots blower for your industry and system needs? What factors should you consider? How do you know which one to buy?
Here are some questions you should consider and expert advice on what factors to weigh up when choosing the right roots blowers for your system needs.
Note: Roots blowers pressure ratings measured in kPa and indicate its performance when considered against flow. So ensure you know the required pressure and flow rate to properly assess which blower fits your requirement.
The performance ratings of roots blowers are influenced by the following factors:
Ensure that the speed at which the gears revolve and its total horsepower works efficiently with your system requirements.
Choose roots blowers made from materials or have particular configurations that help limit the noise output. Pneuvay blowers use vibration isolators and silencers. They can be supplied with acoustic enclosures that are designed to fit.
The efficient performance of roots blowers is dependent on the correct and effective regulation of temperature within the system.
Be mindful of the intensity of heat generated during operation because a slight temperature change can be enough to alter the condition of the material being conveyed into the system.
Test the durability of the roots blower by considering these factors:
Enquire if the supplier offers after sales services to ensure you have someone to assist to in case you require repair and maintenance of your roots blowers. Choose a reputable supplier that has been serving industries for years like Pneuvay Engineering.
Specification should be compared with cost when choosing roots blowers for systems and industries. Pneuvay Engineering offers affordable, durable and reliable roots blowers. Talk to us at or contact us online

Roots blowers are widely used in process applications demanding medium pressures and relatively large flow rates. This includes:
Below is a brief discussion on how roots blowers help optimise system performance, automate difficult processes faster and deliver power saving efficiency to your systems.
Roots blowers are important in supplying oil free clean pressurized or vacuum air to the pneumatic conveying system. However, it is important to choose the right roots blowers that will uniformly deliver and efficiently regulate the processing of materials passing through the system.
This pressurised system is most evident in industries such as:
Industrial vacuum cleaning system with roots blowers for Rio Tinto (Bellbay)
Central vacuum cleaning chambers rely on the efficient suction power of roots blowers in reducing and eliminating dust waste pollution in the workplace. However, the efficient suctioning power of a roots blower is not the only factor you should consider. Arguably, the largest system installed in Australia is at the Port Kembla grain terminal where over 10 km of pipework and operating points were installed.
Some aspects to take into consideration includes:
Our modern roots blower are designed with the following features:
These ensure the machine operator's safety and simplifies the maintenance process.
The refining and oxidation processes involved in processing materials from farms, mining sites and water treatment plants require efficient roots blowers that can supply strong air into the system. This is needed to ensure the temperature level required to reduce moisture, mold development and insect activity inside the storage silos are maintained for these industries:

Air drying is one of the safest ways of product preservation. Roots blowers can deliver humid air at a controlled pressure and temperature. This helps retain most of the properties of these materials. Thus preserving it in a quick, safe and cost effective manner.

It has a wide range of industry applications including:Does your system require higher volume, flow and pressure but reduced power consumption? Need help knowing the amount of volume flow and pressure your system needs for it to efficiently convey materials into your production line?Pneuvay Engineering can help calculate this for you. Tell us the material you need to transport into your systems and we will handle it from there. Contact us online for assistance. Otherwise, see the pressure ratings of our roots blowers to properly assess if it fits your requirement.
Another area, is carb sizing. If you are going to be running a supercharger, ESPECIALLY one that is a bit small for the application, you do not want to under carb the setup. When it comes to these old roots blowers, you need to throw the idea that "my engine only needs 950cfm, so a 950cfm carb will work fine" out the window. You really need to size the carb or carbs, with the consideration that it is no longer gonna be on top of a N/A setup. Things work a little differently on a roots.
Short of running the engine on the dyno and switching carbs, or running it on the lake, and switching carbs, you may never realize you are undercarbed. What happens when you are undercarbed, and lets say you are trying to make 6lbs of boost, but only seeing say 4lbs on the gauge. Naturally you simply install a smaller pulley, to spin the blower harder, to get to 6lbs. When, quite possibly, you just didnt have enough carb, or a restrictive flame arrestor, etc. So by installing a smaller pulley, you just introduced more heat than necessary into the charge.
True story here. I went on a fun run a couple months ago. My engines are 468ci, with 420 B&M blowers, and twin 850 holleys. While on the run, I had noticed my starboard engine was down on boost about 1lb. Never had that happen before. Normally they are both at 6lbs, but the starboard was maxing out at 5lbs. I started to think my blower was wearing, or belt was slipping, or something was going on. Back at the dock i started looking things over. What I noticed, was when I had the carbs apart for a jet change a few days prior to the run, I had pinched the secondary linkage by binding the accelerator pump arm. I put the throttles to wot, and went back and looked down the throats of the carbs. Yup, sure enough, the secondary on only 1 carb, wasnt opening all the way. Mind you, I still had one 850 carb fully opening, and the primary of the other one fully opening. Theoretically, I had cfm of air available. But, it obviously wasnt enough. Now, if I used that little carb cfm calculator, it would have told me that my engine would be just fine with cfm of carb. The real world told me different. Fixed the linkage problem, went back out, and got my 1lb of boost back. How much is 1psi of boost worth on a setup like mine? About 25hp.
Would it be safe to say, that on my engines, going from 1 big ole single dominator, to a pair of twin 850's, would have netted a 25hp gain on the dyno? quite possibly. Its not uncommon to see guys running big massive throttle bodies, or some big twin - dominator carbs, on top of a psi style blower. Its not that the engine really needs - CFM of carb/throttle body, but its the blower that likes it. Basically, you want just enough carb, where the blower doesnt have to work harder than it needs to , to get the desired boost level.
