The 4-72 Model Centrifugal Fan conveys air and other non-flammable, non-toxic gases that do not corrode steel. No viscous substances are permitted within the system. The dust and hard particulate content must not exceed 150 mg/m³, and the gas temperature must not exceed 80°C. This fan employs backward-curved blades with superior aerodynamic properties, delivering smooth operation, high airflow, minimal vibration, high efficiency, and extended service life. It is widely used for ventilation in industrial and mining enterprises, large-scale buildings, hotels, and restaurants.
The 9-26 Type High-pressure Centrifugal Ventilator can be widely used for conveying materials, air, and gases that are non-corrosive, non-self-igniting, and free of viscous substances. The temperature of the conveyed medium generally does not exceed 80°C, and the dust and hard particles content does not exceed 150mg/m³. It is suitable for high-pressure ventilation in general forging and smelting, glass, ceramics, radio, electroplating, storage battery industries, as well as material conveying in processing industries such as grain, feed, mineral powder, and plastics.
The Y5-47 type boiler centrifugal induced draft fan features low noise, simple structure, and flexible adjustment of air volume and direction. It is suitable for industrial boilers fired with various coal types and equipped with smoke and dust removal devices. The temperature of the conveyed gas is ≤250°C. The fan is available in two drive modes: Type C and Type D, both equipped with water-cooled integral bearing housings and air volume regulating dampers.
The SFA premium axial flow fan improves upon the SF model by redesigning the blades and adopting an aluminum alloy casing to enhance the motor’s sealing performance. It features low noise, large air volume, high wind pressure, excellent heat dissipation, and stable operation.
The YWF Series External Rotor Fan is a new product developed by our company through repeated research and trial production. Compared with conventional axial flow fans, this fan features higher efficiency, lower noise, minimal vibration, compact structure, and aesthetically pleasing appearance. The impeller is directly mounted on the outer circumference of the external rotor, resulting in shorter axial dimensions. Its successful development represents a major breakthrough in the field of axial flow fans. This series has obtained multiple national patents.
The FCF Square Kitchen Centrifugal Fan is primarily designed for kitchen ventilation and air exchange. It efficiently expels cooking fumes, heat, and odors generated during food preparation, significantly improving kitchen air quality. By preventing fumes from spreading to dining areas, it safeguards customer experience.
