Detailed Specifications
Impeller Technology
-
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.
-
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.
-
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.
-
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.
-
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.
