11-62A-4 Low Noise High Efficiency centrifugal extractor fan snail fan
11-62A-4 low-noise multi-blade centrifugal fan is designed and manufactured to meet the needs of the increasingly developing purification industry and environmental protection and noise reduction. The fan adopts the multi-objective optimization design method of various aerodynamic parameters such as noise and efficiency in the design, and realizes the best performance matching of the whole machine. It has good aerodynamic performance, and the impeller is corrected by strict dynamic balance, so it has the characteristics of stable operation, low noise, large flow, small vibration and long life.
It is widely used for kitchen exhaust, fume extraction or ventilation in public places such as canteens, hotels, restaurants, etc. It is also suitable for use in food machinery, chemical machinery, plastic machinery and other production equipment.
Feature
* The impeller adopts multi wing forward bending design, which has the characteristics of high efficiency and low noise. The impeller is made of high-quality galvanized steel and has a long service life.
* All copper wire wound motor, high-quality bearing and H-class protection grade motor are adopted, with good sealing, stable performance and longer service life.
* The shell design can realize the interchangeable installation of 0 degrees, 90 degrees and 180 degrees, and the shell surface is treated with spraying technology.
* The fan shell is provided with an oil drain hole, which can take over and drain oil regularly. This model is design basing on leading performance, convenient using and easily maintenance.

The centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas changes to the radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the increase in the cross-sectional area of the duct slows down the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, and secondly in the diffusion process. In a multi-stage centrifugal fan, a recirculator is used to move the airflow to the next impeller, creating a higher pressure.
Effect
The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft in boilers and industrial furnaces; cooling and air conditioning in air conditioning equipment and household appliances. Ventilation; drying and selection of grain; air source of wind tunnel and inflation and propulsion of hovercraft, etc.
Zhejiang Jiayi Fan Co., Ltd. was established in 2003. It is a modern private enterprise focusing on the research, development, production and sales of ventilation equipment. The company is headquartered in Daxi Town, Wenling City, Zhejiang Province, which is the "Hometown of Pumps in China", and has branches across the country; the production base is located in the East New District of Wenling City.
