3) Small equipment adopts the type of export wood packaging and large equipment, and the steel frame transports large cargo transportation.
4) All equipment is waterproof and rainproof.
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.
