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.

Our company has obtained the IS09001 certification from the International Organization for Standardization (see Enterprise Qualification Materials for details). We strictly standardize the operation process and control points of product manufacturing

 

After Sales Service

 

When the equipment of the buyer is installed, our company is responsible for on-site installation guidance, personnel training and commissioning of test-drive, The separately purchased fan accessories can be used for telephone connection guidance and debugging

Our company guarantees that the structural safety, aerodynamic performance, running noise, and appearance, quality of the supplied ventilators can be checked and accepted by relevant departments.

The quality assurance period for the supplied ventilator equipment, except for special provisions, is 18 months from the final acceptance of the ventilator.
