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.
Introduction ▼
The R4Z Series by WingFan is a line of reversible axial fans designed for industrial applications, particularly suited for wood drying and other environments requiring bidirectional airflow. These fans feature a symmetrical blade design, enabling identical airflow performance in both forward and reverse directions, making them highly versatile for dynamic operational needs.
■ High Efficiency & Low Power Consumption: Optimized blade design ensures superior airflow with minimal energy use.
■ Reduced Noise Levels: Engineered for quiet operation, ideal for noise-sensitive environments.
■ Durable & Lightweight Blades:the blades withstand temperatures from -40°C to 150°C and offer exceptional corrosion resistance. Optional anti-corrosive coatings available for harsh conditions.
Blade ▼
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:
■ Light weight High strength
■ Corrosion resistance
■ Customization
■ Smooth

FAQ ▼
Q: Are almost all fans replaceable?A: Yes.
Q: Can they be fitted?A: We can machine the connection holes and bushings, so they can definitely be fitted.
Q: Is it safe to use?A: We will balance and match the angle to the power speed.
Q: Is it possible to replace only the blades?A: No problem, the design is exactly the same.
