Product Description

 

4-79,4-2*79 types of centrifugal fan


The 4-79 centrifugal fan can be used for indoor ventilation in general factories and large buildings, both for inputting and outputting gas. The types of gases transported are air and other gases that do not spontaneously ignite, are harmless to the human body, and are non-corrosive to steel materials. There should be no viscous substances inside the gas, and the dust and hard particles contained should not exceed 150mg/m ³, The gas temperature shall not exceed 80 ºC.
Structural characteristics
The fan can be made into two forms: clockwise rotation or counterclockwise rotation.
The fan mainly consists of an impeller, casing, air inlet, transmission, and other parts equipped with a direct connected motor.
1) The impeller consists of 16 backward inclined circular arc thin plate blades, curved front discs, and flat rear discs, all made of steel plates and subjected to dynamic balance correction. It has good air performance, high efficiency, low noise, and balanced operation.
2) The casing is made into two different forms, and the No.3-12 casing is made into a whole and cannot be disassembled; The casing of No.14-20 is made into two open sections, which are divided into two halves along the horizontal plane of the split and connected by bolts.
3) The air inlet is made into a whole and installed on the side of the fan. The section parallel to the axial direction is curved, allowing gas to enter the impeller smoothly with minimal loss.
4) The transmission part consists of a spindle, a bearing box, rolling bearings, and a pulley.

Our Advantages

 

 

Strict quality standards, precision machining, and other spare parts and design maintain product stability, strictly select product parts suppliers, and perfect after-sales service system to allow customers to enjoy a new experience

Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.

 

Quality assurance measures:

In long-term production management, our company has formed a set of standardized process control measures and control points, which can provide users with high-quality products in all directions. Our company has a good reputation and is an enterprise that users can absolutely trust.
