Features

1. We offer various types of high-density fans, including top-in/top-out and top-in/bottom-out configurations, all available for customization to meet your specific requirements.

2. The fan operates with low noise levels. The fan’s inlet and outlet ports feature a spiral design, allowing air intake and exhaust to occur gradually as the rotor rotates. This eliminates the pulsations and noise caused by the instantaneous opening and closing found in conventional fans, resulting in smooth operation and reduced noise.

3. Impeller machining ensures that the rotor meshing clearance is uniform and consistent, creating a balanced state. On this basis, the rotor undergoes precise dynamic balancing tests, resulting in reduced noise during fan operation.

4. High efficiency, low energy consumption. The fan rotor features a specially designed profile, with an advanced composite curve for its engagement line.

5. After prolonged grinding, the tooth surface exhibits excellent wear resistance.

6. The output air is clean. The fan features a tightly designed structure that prevents oil-based substances from entering the housing, ensuring the output air remains free of oil contamination.

7. Standardized production. All fan products, including accessories, have achieved standardized design and manufacturing.

Installation and Maintenance

1. The installation location must be indoors, protected from wind and rain.

2. The ambient temperature should generally be kept below 40℃.

3. Relative humidity, below 80%.

4. If the conveyed medium contains corrosive or flammable gases such as acids or alkalis, special design is required to prevent potential hazards.

5. Dust Protection: In areas with significant dust, powders, or fibers, install filters and regularly clean the dust accumulated on filter screens and inside the fan units.

6. Ensure proper ventilation and heat dissipation—use in a well-ventilated area only. Do not use in small, enclosed spaces or sealed boxes.

7. Provide ample space to facilitate routine maintenance and repairs, and avoid installing in overly cramped areas.

8. Avoid vibration by installing in a vibration-free environment; if vibration at the installation site is unavoidable, vibration-damping measures should be implemented.

After-sales service

1. Train maintenance and operation personnel for customers, and provide users with spare parts promptly and conveniently.

2. Build a high-quality industry service brand with 24-hour support.

3. After the company ships the product, dedicated after-sales customer service representatives will follow up with usage checks during the first, third, and sixth months.

4. Provide pre-sales selection solutions and technical support for drawings.

5. Customer inquiries will be responded to within 2 hours.

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.

Rotary lobe blower specifically designed for aquaculture

The RotoBlower specifically designed for livestock and aquaculture is a widely used piece of equipment in both animal husbandry and fish farming, primarily serving functions such as ventilation, air exchange, and oxygen enrichment. It boasts high ventilation efficiency: effectively reducing temperature and humidity levels in farms, minimizing odors and dust, and improving air quality—thus creating an optimal growing environment for livestock, poultry, and aquatic organisms.

FSR Three-Blade Roots Blower

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.

High-Pressure Roots Blower

The high-pressure Roots blower operates by two non-contacting rotors that move in opposite directions at the same speed inside the cylinder, pushing the airflow from one side to the other. As the high-speed air stream approaches the exhaust port and momentarily connects with it, a sudden pressure surge occurs due to the backflow of higher-pressure gas within the working volume—this forces the compressed air out of the system. The high-pressure Roots blower relies on synchronized gears at the ends of the rotor shafts to keep the two rotors engaged. Each recessed curved section on the rotors forms a working volume in conjunction with the inner wall of the cylinder; as the rotors rotate, they draw in air from the intake port. This process continues as the two rotors alternate their operation sequentially. By increasing power, reinforcing the rotor assembly, expanding the overall volume, boosting rotational speed, and fine-tuning the impeller clearance, the blower further intensifies air compression within the cavities, thereby elevating the output pressure.
