Applications

Regenerative blowers are commonly used in industrial applications, such as wastewater treatment, pneumatic conveying, and chemical processing, where high volumes of air are required at low pressures. They are also used in some automotive applications, such as supercharging engines, where they can increase the amount of air that is forced into the engine, resulting in increased horsepower and torque.

Tips: Are regenerative blowers noisy?

Regenerative blowers are typically louder than other types of blowers due to their design and operation. The pulsating airflow generated by the blower as it moves air through the system creates a distinct "whining" or "whistling" noise, which can be particularly noticeable at higher speeds.

However, the level of noise produced by a regenerative blower can vary depending on a number of factors, including the specific model and size of the blower, the speed at which it is operating, the design of the intake and discharge systems, and the acoustic characteristics of the surrounding environment.

In general, regenerative blowers tend to be louder than other types of blowers, such as centrifugal or axial flow blowers, but there are ways to mitigate the noise produced by a roots blower, such as using sound-dampening materials, optimizing the blower's installation and placement, and selecting a blower with a lower noise output.
