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. "
