 Impeller Technology

1. Forward Curved Centrifugal Fan: Large Airflow and Low Sound

• The forward curved wheel has larger airflow than the backward inclined wheel at the same speed.

• The forward curved wheel has lower speed and sound than the backward inclined wheel under the same operating condition.

• The inlet bell formed by spinning is carefully matched to the wheel cone for better air movement and lower sound.

2. The Backward Inclined Centrifugal Fan: Great Efficiency and Non-overloading

• The backward inclined wheel has greater efficiency than the axial wheel, mixed flow wheel and forward curved wheel.

• The V-shaped baffle is mounted at the outlet to effectively reduced turbulence, lower sound and improve efficiency.

• The backward inclined wheel has smooth non-overloading performance curves ensuring safer operation.

3. Advanced Technology to Ensure Accuracy

• The scroll is manufactured with Pittsburgh lock seams sealing techniques for zero air leakage.

• The side panels are once formed with high precision to reduce dimension errors.

• The blades are once formed by punching, and dedicated fixtures used for precise mounting positions.

4. More Reliable Structural Design

• The threaded rod is applied as reinforcement for the forward curved wheel for reliable and durable operation.

• The backward inclined wheel is enhanced with stiffeners for durable and safe operation.

• The fan is supported by stable channel steel frame for stable fan operation.

5. High Balance Quality Grade

• Balance quality grade of G2.5.

• Vibration reduced and reliability improved.

• Sound greatly reduced.

General Features

1. Sealed Cabinet Structure for Lower Sound
