High-Flow Centrifugal Fans for Delivering Clean Air at Room Temperature

Our high-flow centrifugal fans are engineered to deliver large volumes of clean, uncontaminated air at room temperature, making them ideal for ventilation, cooling, and air supply applications across various industries. Designed with aerodynamically optimized impellers and precision-balanced components, these fans ensure efficient and stable airflow while minimizing energy consumption and operational noise.

Constructed from high-quality, non-corrosive materials, the fans maintain air purity and are suitable for environments where clean air is critical, such as in food processing, pharmaceutical manufacturing, electronics cleanrooms, and commercial HVAC systems. The robust design supports continuous operation with minimal maintenance, providing long-term reliability and consistent performance.

Customizable in size, capacity, and configuration, these centrifugal fans can be tailored to meet specific airflow requirements and spatial constraints. By combining high flow rates with energy-efficient operation, they offer a sustainable and cost-effective solution for maintaining optimal air quality and comfort in industrial and commercial settings.

• Type of fan: Viewed from the side of the motor, the impeller that rotates clockwise is called a right-handed fan ("right"); counterclockwise is left-handed ("left").
• Outlet position: Expressed by the angle of the air outlet of the casing. 4-72 type fans №2.8～6 are made as one type, adjustable during installation.
• Transmission modes: A, B, C, and D types available depending on fan size.

• Impeller: Composed of 10 backward inclined airfoil blades, curved front disc and flat rear disc. Made of steel plate with dynamic and static balance correction.
• Shell: №2.8～12 made as one piece; №16～20 made as three open types with bolt connections.
• Air inlet: Curved switch design for smooth airflow entry with minimal loss.
• Transmission: Consists of main shaft, bearing box, flow bearing, and pulley/coupling.

Widely used in boiler ventilation, energy recovery, environmental dust removal, desulfurization and denitration conditions.
