Description
4-72centrifugal fan
4-72centrifugal fan is a high-efficiency and energy-saving centrifugal fan. Its airfoil-shaped blades, curved impeller front disk and cone-shaped inlet collector make the fan have excellent aerodynamic performance and play an important role in my country’s economy. In the construction industry, it has been enduring for many years.The 4-72 type centrifugal fan is suitable for air supply, exhaust and general ventilation in various civil and industrial buildings. It is mainly composed of impeller, impeller casing, air inlet and motor. The direction of rotation is divided into right rotation and left rotation, viewed from one end of the motor.

Advantage
1. The ventilation effect is good. The 4-72 centrifugal fan has a good exhaust effect and is very suitable for use in duct exhaust or air supply;
2. Strong applicability. The 4-72 centrifugal fan is commonly used in pipelines to transport air. It can be used in places without corrosion, flammable and explosive gases.
3. Low noise. The 4-72 centrifugal fan adopts a reasonable impeller angle design based on air flow mechanics. During operation, there is no mechanical friction and the reasonable blade shape minimizes the noise; the noise generated by the 4-72 centrifugal fan It is high-frequency noise and can be soundproofed as long as there are obstacles.
4. Smooth operation. The optimized design of the impeller reduces the axial force to a minimum. It has an efficient impeller and has been corrected by static and dynamic balance to make the whole machine run smoothly. Without any vibration reduction device, the bearings The amplitude is relatively small.
5. Less maintenance, because the impeller adopts a backward tilt type, which is not easy to adhere to dust and other media, and the motor uses imported bearings.
6. It is easy to maintain. Some models can be equipped with cleaning doors, so there is no need to disassemble the machine for maintenance and cleaning, saving time and effort.
7. Sturdy and durable, the casing and impeller are made of high-quality steel plates, making the fan stronger. The surface of the whole machine is spray-coated, which has strong oxidation resistance and is not easy to be rusted.
