It is a mechanical device used to transport and pressurize gases. It works by using two internally meshing impellers to draw in gases from the place where they are compressed and then discharged from the outlet.

The Roots blower derives its name from the German engineer Joseph von Roos, who developed the device in the early 19th century for use in mine ventilation.

The Roots blower is a centrifugal fan, but unlike traditional centrifugal fans, it does not generate airflow by rotating an impeller, but rather the gas is compressed by two rotating impellers that engage with each other.

The design of these impellers allows Roots fans to provide high flow rates for gas delivery at low to moderate pressures, making them ideal for use in industrial applications such as water treatment, chemical processing, and wastewater treatment.

In addition to conveying gases, Roots blowers can also be used for gas pressurization.

In this application, Roots blowers are used to compress gases to high pressures for use in industrial processes or for increasing the efficiency of gas generators.

The high efficiency and reliability of Roots blowers make them one of the gas conveying and pressurizing equipment used in industry.

Roots blowers basically work by compressing gas through two rotating impellers.

The gap between these impellers is very small so that the gas is compressed efficiently.

When the Roots blower begins to operate, the gas flows in, is compressed by one rotating impeller, and then flows through the second rotating impeller for further compression.

The gas is compressed to the required pressure and discharged at the outlet.

The advantages of Roots blowers are their high efficiency, reliability and low noise level.

They do not use oil lubrication and can therefore operate in harsh environments, such as those with high temperatures and high humidity.

In addition, the design of Roots fans makes them easy to maintain and clean, so they can remain efficient after a long period of use.

Overall, Roots blowers are a very important piece of industrial equipment used for gas transportation and gas pressurization.

They are widely used in industry because of their high efficiency, reliability and low noise levels.
