TRE series single inlet forward curve air condition centrifugal fan
The fan adopts advanced technology. Design of forward curved centrifugal wheel is optimized by means of CFD hydro-field simulating. The design is more accordant with the aerodynamic characteristics, and high efficiency, and stable airflow.
Advanced cutting process, precise positioning jig and all-welded technique are adopted for the blade to ensure smoothness of the margin of the blade. The welding angle is accurate, the whole blade is with strong strength, and the stress is evenly distributed during long-time high-speed operation. The operation is stable and reliable.
High static pressure
Selecting fans featured in forward curved blade with high pressure coefficient has the advantages of smaller model and lower costs than other fan types under meeting the same working point, and has a lower speed, which may decrease vibration and sound level obviously and make fan work more quietly and steadily comparing with the same model of other fan types.
Smaller radio of width and diameter and longer blade flow passage make forward curved wheel more compact and stronger, which may bear a bigger stress and ensure a reliable running.
High balancing level
Each wheel is subjected to dynamic balance test. We insist to the balancing level of G4.0 (Typical products are balanced to G6.3 only). Long-term quiet and stable running of the fan is ensured fundamentally.
1. Smaller radio of width and diameter and longer blade flow passage make forward curved wheel more compact and stronger, high strength and safety.
2. To be adopted FEA-aided design for enhancing the reliability of structure
3. Scroll and wheel with high strength and no leakage characteristics are all-steel continuous welded to improve operation safely
4. Each wheel is balanced, and balancing level is higher than the GB product G6.3 (ISO1940)
5. To be vibration tested before the fan leave the factory to achieve the requirements of long-term stable and re
