High-Flow Centrifugal Fans for Delivering Clean Air at Room Temperature

1. Applications for Single Inlet Centrifugal Fan for Boiler

Our high-flow centrifugal fans are engineered to deliver large volumes of clean, uncontaminated air at room temperature, making them ideal for ventilation, cooling, and air supply applications across various industries. Designed with aerodynamically optimized impellers and precision-balanced components, these fans ensure efficient and stable airflow while minimizing energy consumption and operational noise.

Constructed from high-quality, non-corrosive materials, the fans maintain air purity and are suitable for environments where clean air is critical, such as in food processing, pharmaceutical manufacturing, electronics cleanrooms, and commercial HVAC systems. The robust design supports continuous operation with minimal maintenance, providing long-term reliability and consistent performance.

Customizable in size, capacity, and configuration, these centrifugal fans can be tailored to meet specific airflow requirements and spatial constraints. By combining high flow rates with energy-efficient operation, they offer a sustainable and cost-effective solution for maintaining optimal air quality and comfort in industrial and commercial settings.

☆Type of fan
Viewed from the side of the motor, the impeller that rotates clockwise is called a right-handed fan, which is represented by "right"; the impeller that rotates counterclockwise is called a left-handed fan, which is represented by "left".
The outlet position of the fan is expressed by the angle of the air outlet of the casing. 4-72 type fans №2.8～6 are all made into one type when they leave the factory, and the user can install them in the required position according to the requirements, and there is no need to specify when ordering. Among them, the adjustment range of the air outlet position of №2.8 is 0°～255°, and the interval is 45°; the air outlet positions of №16 and 20 are made into three fixed positions of 0°, 90°, and 180°, which cannot be adjusted, and must be specified when ordering .
There are four kinds of fan transmission modes: A, B, C, and D: among the 4-72 type fans, №2.8~6 adopts A type transmission, №8~12 adopts C and D type transmission, and №16~20 adopts B type transmission .
☆The structure of the fan
№2.8～6 of the 4-72 type fan is mainly composed of impeller, casing, air inlet, motor and other parts. №8～20 has not only the above-mentioned parts, but also a transmission part.
(1) Impeller: It is composed of 10 backward inclined airfoil blades, a curved front disc and a flat rear disc. It is made of steel plate and has been corrected by dynamic and static balance. The air performance is good, accurate and the operation is stable.
(2) Shell: made into two different types. Among them, the casings of №2.8～12 are made as a whole and cannot be disassembled. The casings of №16～20 are made into three open types. In addition to being divided into two halves along the middle horizontal plane, the upper half is vertically divided into two halves along the center line. , connected with bolts.
(3) Air inlet: It is made as a whole and installed on one side of the fan. The section parallel to the axial direction is a curved switch. The function is to make the airflow enter the impeller smoothly, and the loss is small.
(4) Transmission: It consists of a main shaft, a bearing box, a flow bearing, a pulley or a coupling.

2.performance parameters

Flow rate: 20~500m3/s, pressure range: 2000~20000 PA, gas temperature is 200℃.

3. the main purpose

Widely used in boiler ventilation, energy recovery, environmental dust removal, desulfurization and denitration conditions. "
