Backward Curved SWSI Centrifugal Fan – Wheel Type I – YFBCSI

 Impeller Technology

1. Optimized Design

The fan adopts advanced technology. The design of backward curved centrifugal impeller is optimized by means of CFD hydro-field simulating. The design is more accordant with the aerodynamic characteristics, high efficiency, and stable airflow.

1. Advanced Process

All steel laser cut blades are welded and positioned accurately. The overall strength of the blades are designed and welded to withstand long hours high speed operation.

1. High Balancing Level 

Each impeller is subjected to dynamic balance test. The balancing level is kept at G4.0 (Typical products are balanced to G6.3 only). Durability, stability and quietness are guaranteed.

1. High Performance Curve

The impeller has a stable, smooth air performance curve which can efficiently avoid performance drop caused by the deviation of the working point.

1. Surge Protection

The fan shaft power will not exceed the motor rated power regardless the operation point of the stable working range. Customers can use it without any worries.

 General Features

1. High Reliability

• Our products use advance FEA-aided design to enhance the reliability of structure.
• The hub and the impeller are strengthened and leak-proof thanks to the all-steel continuous welding method. Safety is also significantly improved during operation.
• The new shaft and coupling technology ensuring the accuracy during the assembly process while maintaining high reliability.
• Maximum load surpasses 35% of limit speed to ensure the long-term continuous operation of the security.
• Bearing seal can be lubricated to ensure operation reliability and durability.
• The drive unit has a protective shield using eye-catching warning color to ensure personal safety.
• All our machines underwent vibration tests prior leaving the factory in order to achieve reliable and durable operation.

1. High Efficiency

• Venturi inlet shall match the front disc precisely to avoid turbulent flow and air leakages, so that the air flows more smoothly to improve aerodynamic performance.
• Optimized design repeatedly of CFD flow field simulation to ensure aerodynamic performance complied with the flow field characteristics.
• Excellent aerodynamic performance.

1. User Friendly

• Flexible motor allocation.
• Wide range of standard accessories available.
