Forward Curved Steel Centrifugal Wheel - Type C
The design of the forward curved centrifugal wheel is optimized through advanced technologies and CFD simulation. It is more accordant with the aerodynamic characteristics and features great efficiency and more stable airflow.
The advanced cutting process, precise positioning jig and continuously welded technique help to ensure smooth blade edges. The accurate welding and high strength of blades produce evenly distributed stress reliability in long-term high-speed operation, thus ensuring reliability.
High Static Pressure
The forward curved blades with the best pressure characteristics and high static pressure are used. In model selection, this blade design makes smaller wheel diameter that has lower price/performance ratio the choice. When the wheel diameters are the same, there will be lower RPM, greatly reduced vibrations and sound, quieter and more stable operation by virtue of this design.
Smaller width-diameter ratio and longer blade passage make the wheel more compact and strong enough to withstand more stress. Also, the fan operation will be more reliable.
High Balance Quality Grade
Each wheel has been dynamically balanced up to G4.0 standard (Just G6.3 for general products). This has ensured the long-term quiet and stable fan operation.
● Smaller width-diameter ratio and longer blade passage make the wheel more compact, stronger and safer.
● The fan design is aided by the FEA method for greater structural reliability.
● The scroll and wheel are continuously welded with high strength and no leakage, improving the operational safety.
● Each fan wheel has been dynamically balanced. The balance quality grade is above the national standard of G6.3 (AMCA204).
● The Model YFFCSC fan has undergone vibration tests before leaving the factory for long-term stable and reliable operation.
● The fan shaft has been treated through hardening and tempering and finish turning processes. Its maximum load is 35% more than the highest running speed of the fan to ensure the long-term safe operation.
● The bearing is sealed and can be lubricated. Its L10 rating service life is in excess of 80000 hours to ensure the long-term reliable operation.
● The design is optimized through CFD simulation and repeated tests to ensure the aerodynamic performance conforms to the flow field characteristics.
● The efficient centrifugal wheel with wide performance range of high efficiency avoids a drop in performance when the operating point moves up or down.
● The wheel cone is carefully matched to the inlet cone for precise running tolerances to avoid turbulence and air leakage and to improve airflow movement and air performance.
● Excellent air performance with the highest efficiency grade up to FEG80 (AMCA205)
● Different drive types available for flexible selection
● Various commonly used accessories provided
●Complete range of accessories to meet different application scenarios.
The fan shall be forward curved steel single-inlet centrifugal type. It shall be direct or belt driven. The fan shall be designed to allow the wheel to be removed for maintenance and cleaning.
