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.

Intensive Roots Blower

The intensive three-lobe Roots blower features an involute profile, employs forced lubrication for safe and reliable operation, and boasts a mid-split casing and wall plate design that ensures convenient maintenance. It can meet the diverse needs of users and incorporates advanced counter-flow noise-reduction technology, along with comprehensive self-protection mechanisms. Additionally, the unit boasts a compact, space-saving design that makes installation effortless.

By increasing power, reinforcing the rotor assembly, expanding the overall volume, boosting rotational speed, and fine-tuning the impeller clearance, the blower further intensifies the compression of air inside the cavities, thereby raising the pressure even higher.

Bipolar Series Roots Blower

A two-stage Roots blower is a device composed of two three-lobe Roots blowers connected in series. Each blower unit features two counter-rotating, three-lobe rotors inside its housing, with each rotor supported by two bearings. A pair of high-precision, synchronizing straight gears ensures that the relative positions of the two rotors remain constant at all times. This design maintains a consistent gap between the rotors and between the rotors and the housing, enabling non-contact rotation. Driven by the synchronous gears on the side housing, the rotors utilize their "meshing" action to separate the inlet and outlet ports, thereby sealing the gas within the housing and transferring it smoothly from the suction side to the discharge side.
