If there's any needs in roots blower, pls share specifications you need with us, such as flow rate and pressure, our engineers will provide proper models accordingly.

The impellers of the HG three-lobe Roots blower adopt a thin involute profile, and the impeller and shaft are integrally designed with a well-optimized structure. This design offers high efficiency, premium material quality, long service life, low noise, and low vibration.

The blower uses a forced lubrication system and can operate at a pressure rise of up to 98 kPa without water cooling. With its integral structure, the unit is compact in size, requires minimal installation space, and does not need a special foundation — a flat concrete surface is sufficient. The blower is also equipped with built-in vibration isolators, making it especially suitable for elevated installation positions.

The HG series Roots blower is an upgraded product developed using our proprietary technology. Its structure and performance have been significantly enhanced, offering reliable operation and excellent cost performance.

Additionally, the HG series features dimensional compatibility with certain Robuschi roots blower models, making it a practical option for replacement projects and system upgrades where matching interfaces are required.

The following is a detailed introduction of Roots blowers used in different industries:

1. Wastewater treatment

Aeration: Roots blowers are used to provide air to the aeration tank of the wastewater treatment facility. This helps maintain aerobic conditions, which are essential for microbes to break down organic matter.

Sludge treatment: They also help transport the sludge and facilitate the mixing and agitation required for effective treatment.

2. Pneumatic conveying

Bulk material transport: In food processing, pharmaceutical and chemical industries, Roots blowers are used to transport bulk materials through pipes. They can effectively handle powders, particles and pellets.

Powder handling: For industries that handle fine powders, Roots blowers provide a controlled and stable flow rate that minimizes dust and spills.

3. Industrial processing

Combustion air supply: During the combustion process, Roots blowers can provide the necessary air for the burner and furnace, ensuring the efficient combustion of fuel.

Cooling and ventilation: They are used in various cooling systems to move air and maintain temperature control during manufacturing.

4. Chemical and petrochemical industries

Gas delivery: Roots blowers are used to transport and compress gases in chemical processing, including handling dangerous or corrosive gases.

Process air supply: They provide air for a variety of chemical reactions that require precise control of air flow and pressure.

5. Food and beverage industry

Packaging: In packaging operations, Roots blowers are used to create and maintain vacuum conditions or to fill packaging with inert gas to extend shelf life.

Fermentation: They help fermenters, yeast or bacterial cultures that provide air or oxygen to grow.

6. Mining and quarrying

Ventilation: Roots blowers are used to provide ventilation in underground mines and quarries, ensuring the supply of fresh air and the removal of harmful gases.

Dust control: They help control dust by providing air to dust suppression systems.

7. Medicine

Clean room environment: In pharmaceutical manufacturing, Roots blowers maintain clean room conditions by providing controlled airflow and pressure.

Material handling: They are used to handle sensitive materials that require precise flow and sealing.

8. Cement industry

In the cement manufacturing process, the main applications of Roots blowers have two aspects:

(1) Pulverized coal transport: Pulverized coal is blown into the combustion furnace by Roots blower for combustion.

(2) Flue gas treatment: A certain amount of gas is generated in the cement production process, which requires flue gas treatment, and Roots blower is one of the core equipment of the flue gas treatment system. It can help move smoke and dust and send the smoke into the electrostatic precipitator for purification.
