HRW single inlet backward fan

 
 backward curve inlet centrifugal air conditioning fan
1)work reliable,low noise 
2)high efficiency,save energy 
3)ce, amca
 
optimized design
-- wheel uses the advanced technology, optimized design of cfd flow field simulation for backward cured centrifugal wheel. it means blade sectionhasacertain radian, not a straight line; the angle between air flow direction and blade velocity direction is blunt angle.
advanced process
-- steel laser cutting, precise positioning jig and all-welded technique are adopted for the blade to ensure smoothness of the margin of theblade.thewelding 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 andreliable.
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-termquietand stable running of the fan is ensured fundamentally.
high-efficiency range
-- the wheel has a stable and smooth aerodynamic performance curve and owns a wide range of high efficiency working area which can efficientlyavoidfanperformance decrease caused by the deviation of the working point.
non-overload
-- the series wheel exist a peak value of shaft power, when the motor is selected according to the power combined with the margin factor of motorpower,thefan shaft power will not exceed the motor rated power no matter on which operation point of the stable working range the is running, then the clients can use it at ease.
