Product Description

Product Description

R4Z
The R4Z series axial flow fansare developed according to the need for fan reversal in some occasions. The symmetrical blade shape design allows the same flow of air in both positive and negative directions. Compared with ordinary fans, the second blade separated by R4Z fan is installed at 180 °. UTEK-DELE's fans of this series have the following advantages:

1.More efficient
2.Less absorbed power
3.Low noise


The fan diameter ranges from 299 to 1011mm, and the blade twist angle can be adjusted from 15°to 40° to meet the different application requirements of the customer. The R4Z owns Z-type blade root (patent No.2439767), which has become the international standard for blade root of the same type. The root of the blade is locked in the corresponding fan hub through the steel locating pin to ensure that the blade installation will not be displaced and the torsion angle will remain unchanged. Blades machined by aluminum alloy die casting process can work in the range of -40ºC to 150ºC, and have the following significant characteristics:

1.Light weight High strength
2.Corrosion resistance
3.Customization
4.Smooth
