What is a root blower
- Roots blower is a volumetric blower, also called a rotary blower, which is mainly used to transport gas. It compresses and transports gas through relative movement of two blade-shaped rotors in the cylinder, and is a type of rotary compressor.
- Roots blowers have a simple structure and are easy to manufacture. They are widely used in various industrial fields, such as aquaculture oxygenation, sewage treatment aeration, cement transportation, etc. It is particularly suitable for gas delivery and pressurization systems in low-pressure situations, and can also be used as a vacuum pump.
- The principle of Roots blower is to use two blade-shaped rotors to make relative motion in the cylinder to compress and transport gas.
- This design makes the Roots blower have the characteristics of forced air transmission, and the air volume it delivers is proportional to the number of revolutions.
- There is a slight gap between the impeller end face of the Roots blower and the front and rear end covers of the fan.
- Driven by the synchronization gear, the gas is transported from the air inlet along the inner wall of the casing to the discharge side. This design makes the Roots blower relatively simple to operate and easy to maintain.

Root blower working principle
- The working principle of Roots blower can be simply summarized into the following steps:
- 1.Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
- 2.Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
- 3.Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
- By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

Roots blower uses
- Roots blowers are widely used in many industries and fields, mainly including:
- Sewage treatment: In the sewage treatment industry, roots style blowers are widely used in aeration, stirring, mixing and other aspects to ensure the smooth progress of the sewage treatment process.
- Pneumatic conveying system: roots style blowers are used to transport feed, lime powder, monosodium glutamate, soybean skin, silica and other powdery materials, as well as grain suction machines or crane suction vacuum pumps in grain transportation to ensure the effectiveness of materials transmission.
- Aquaculture: In aquaculture, roots style blowers use micropore aeration technology to oxygenate water quality and improve breeding efficiency.They are important equipment in the aquaculture industry.
- Coal chemical industry: In the coal chemical industry, Roots blowers are used in sewage treatment and different processes, playing an important role in improving production efficiency and product quality.
- Dust removal industry: Roots blowers are also used in the dust removal industry, such as desulfurization, denitrification, dust removal, etc., to ensure the effective treatment of industrial flue gas and waste gas.
- Grain processing, flour mills, food factories: used in transportation, drying, cooling, dust and other links to ensure the smooth progress of the food processing process.
- Paint and Coating Industry: Used for ventilation, dust removal and waste gas treatment to ensure the safety and health of the working environment.
- Mining, quarrying, and mineral processing industries: used in emissions, exhaust, gas transportation, drying and other links to ensure environmental control and safety during the development of mineral resources.
- Pharmaceutical Industry: In the pharmaceutical industry, Roots blowers are used in pharmaceutical processing, chemical reactions and other aspects, such as laboratory ventilation equipment, to ensure the safety and efficiency of the pharmaceutical production process.
