Roths Roots Blower for Wastewater Treatment
The sewage treatment Roots blower injects high-pressure air into the surface or bottom layers of the water body, continuously driving water flow in a circular motion to thoroughly mix and agitate the wastewater. This process significantly increases the contact area between water and air, boosting oxygen levels in the aquaculture ponds. As a result, organic matter, microorganisms, and oxygen are fully mixed and come into close contact, providing essential oxygen for aerobic microorganisms to thrive. Moreover, the sewage treatment Roots blower combines both aerobic aeration and anaerobic mixing functions, effectively accelerating water circulation and helping to break down long-term accumulated organic matter before it has a chance to decompose. It also plays a crucial role in pre-aeration, odor control, preventing anaerobic decomposition of wastewater, and even reducing foam formation—making it an indispensable tool for maintaining clean and healthy aquatic environments.

Rotary Lobe Blower Specifically Designed for Pneumatic Conveying
The dedicated Roots blower for pneumatic conveying utilizes a dual-lobe rotor design, creating a tight seal within the impeller to achieve high conveying efficiency—up to 20% higher than conventional blowers. Its symmetrically balanced impellers ensure uniform airflow distribution, enabling stable operation with minimal vibration and noise. Additionally, the blower features automatic adjustment of inlet pressure and is constructed from wear-resistant materials, offering excellent durability. With its oil-free lubrication design, it guarantees safety and reliability, making it ideal for transporting various granular or powdered materials, such as coal, ores, grains, and more.

Desulfurization Oxidation Blower
In desulfurization systems of thermal power plants, steel mills, and other facilities, the desulfurization oxidation blower delivers compressed air to the desulfurization tower, oxidizing calcium sulfite into calcium sulfate, thereby ensuring both desulfurization efficiency and the purity of the byproduct. Featuring stable flow rates and a wide pressure range, this blower can handle mixed gases such as ammonia and air without oil contamination. Key components are made from corrosion-resistant materials, making them well-suited for use with corrosive gases like ammonia.

The FSR Three-Lobe Roots Blower is a dual-rotor synchronous compression machine, with each three-lobe rotor supported by two bearings. It employs a pair of synchronized gears to ensure that the relative positions of the two rotors remain constant at all times. As a positive-displacement blower, it features forced air delivery. Widely used across numerous industries—including petrochemicals, building materials, power generation, metallurgy, fertilizer production, mining, ports, light textiles, food processing, papermaking, aquaculture, wastewater treatment, and environmental protection—the blower is primarily employed for conveying air. When properly sealed, it can also handle flammable, explosive, and corrosive gases such as coal gas, hydrogen, acetylene, and carbon dioxide.
