PERFORMANCE
The CF-11 series multi-vane, low-noise centrifugal fans feature a forward-curved multi-vane impeller. The blades are constructed from galvanized steel, ensuring high strength and resistance to deformation while delivering high static pressure and low noise levels. These fans are available in both clockwise and counter-clockwise rotation configurations (please refer to the fan orientation selection chart).
Inlet: Manufactured as a single, molded unit and mounted on the side of the fan housing. The inlet profile features a curved shape parallel to the axis, facilitating smooth airflow into the impeller with minimal loss.
These fans offer high efficiency and high airflow capacity. Their innovative design ensures a compact footprint, ease of installation, and operational flexibility, making them well-suited to modern environmental standards.
The company follows the service principle of “user first” and has set up a professional technical support team dedicated to serving every customer with care.
