Industrial Applications

Food Processing and Pharmaceutical Industry

Centrifugal fans play a critical role in maintaining hygienic and controlled environments in food processing and pharmaceutical manufacturing. These industries require precise control over temperature, humidity, and air cleanliness to ensure product safety and quality. High-efficiency supply and exhaust fans are commonly used to circulate fresh air and remove heat, moisture, or contaminants from production areas. Low-noise designs are particularly important in laboratories, clean rooms, and production lines where noise levels can impact worker comfort and compliance with occupational standards.

Airflow optimization in food and pharmaceutical facilities is vital to prevent contamination and maintain consistent environmental conditions. Fans must often meet strict hygiene standards, including easy-to-clean surfaces and materials resistant to corrosion or chemical cleaning agents. Additionally, centrifugal fans are used in drying ovens, cooling tunnels, and packaging lines, where precise airflow ensures uniform processing and reduces production variability.

Chemical and Petrochemical Industry

In chemical plants, centrifugal fans must meet rigorous safety and performance requirements. Explosion-proof fans are essential in handling flammable, volatile, or hazardous gases, preventing sparks or ignition while maintaining effective airflow. High-pressure fans are often used to move air through ductwork with high resistance, supporting processes such as fume extraction, ventilation of reaction chambers, and industrial drying.

Environmental compliance is a significant driver in chemical industries. VOC exhaust fans remove harmful volatile organic compounds from production areas, protecting worker health and meeting environmental regulations. Fans designed for chemical plants often use corrosion-resistant materials and high-precision engineering to withstand aggressive chemicals, high temperatures, and continuous operation.

Steel and Energy Industry

Steel production and energy generation industries often operate in high-temperature and high-pressure environments. High-pressure fans are essential in boilers, furnaces, and material conveying systems. High-temperature resistant fans are designed to withstand extreme heat, providing consistent airflow without performance degradation. Efficient fan operation in these sectors contributes to energy savings and operational reliability.

Material handling in steel mills and power plants also requires durable fans capable of moving abrasive particles or gases containing dust. Dust extraction fans ensure clean air circulation, protect equipment, and improve workplace safety.

Photovoltaic, New Materials, and Electronics Manufacturing

Precision and cleanliness are critical in these industries. Centrifugal fans are used for dust removal, temperature control, and ventilation in electronic assembly areas, photovoltaic cell production, and new material processing. Material conveying fans help transport powders or granules, while low-noise fans maintain quiet environments suitable for sensitive equipment and worker concentration. High-efficiency fans reduce energy costs, which is particularly important for large-scale manufacturing facilities.

Optical Fiber/Preform Manufacturing and Glass Industry

The production of optical fibers, preforms, and glass requires highly controlled airflow to maintain material quality. High-temperature and high-purity fans are used to remove heat, gases, and dust without contaminating products. In regenerative thermal oxidizer (RTO) systems or VOC management, centrifugal fans ensure safe and environmentally compliant exhaust. These applications often demand fans that can withstand continuous operation under extreme conditions while maintaining consistent performance.

Product Types and Technical Comparison

TF series centrifugal fans are available in various types, each designed to meet specific industrial needs. Understanding the differences between these fan types helps engineers and facility managers select the most suitable solution for airflow, pressure, temperature, safety, and environmental requirements.
