NJF NJF series aluminum alloy hollow type cooling tower fans are innovatively engineered to enhance the performance of cooling towers, providing significant benefits over traditional fans. Each blade is meticulously enhanced for whisper-quiet operation, ensuring optimal airflow and pressure capabilities while operating at a reduced speed. The NJF fan's exterior boasts high-quality aluminum alloy, meticulously infused with pigment to ensure flawless and uniform distribution across the laminate. The blades are securely connected to the fan hub via a robust, heavy-galvanized iron ring, expertly molded with each blade. Simply by adjusting the hub attachment hardware, blades can be effortlessly rotated to the desired pitch, allowing for the maximized utilization of fan horsepower.
High transmission efficiency: Precision-crafted aluminum alloy airfoil blades ensure superior transmission efficiency.
Lightweight: Constructed from high-strength aluminum alloy material, ensuring durability and ease of installation.
Excellent balance: Each fan undergoes rigorous precision testing for weight matching and balance, ensuring smooth operation with enhanced stability.
Exceptional anti-corrosion ability: Advanced surface oxidation treatment significantly enhances the fan's resistance to corrosion, ensuring long-lasting performance.
TECHNICAL PARAMETERS
The connection of fan blades to the hub employs a robust heavy-galvanized iron ring, which is seamlessly molded with each fan blade. This innovative design allows for easy blade rotation by simply loosening the hub attachment hardware, enabling you to adjust the pitch to your desired angle. As a result, you can achieve optimal fan horsepower utilization, ensuring efficient and smooth operation.

FAN ASSEMBLY INSTRUCTIONS
The Newin NJF series, renowned for their hollow type aluminum alloy fans, are delivered in an unassembled form. This allows for easy transport and storage. Each fan blade and hub are matched meticulously to guarantee a seamless re-assembly process, ensuring that your fan operates at its peak performance.
a. Select a wide open area to accommodate the fan's diameter, providing ample space for assembly and operation.
b. Position the fan hub at the center of this designated work area, ensuring the blade sockets are correctly oriented for assembly.
c. Carefully place fan blade 2 into a blade socket on the hub. For fans where blade overlap occurs at the hub, ensure the leading edge is positioned under the trailing edge of the adjacent forward blade for correct assembly.
d. Ensure that the blade shank safety collar is positioned inboard of the inner hub rim for optimal safety and performance.
1. Ensure the cooling tower motor is securely locked out to guarantee safety during installation.
2. Thoroughly clean the hub bore and the driving shaft extension throughout the entire length of the key to ensure a precise fit.
3. Carefully insert the key into the keyway. Make sure the top of the key is positioned no more than 3 mm below the top of the shaft. The key must fit tightly across the width and should never be altered.
4. After ensuring all components are clean, apply a coat of anti-seize compound to the shaft's engagement portion to prevent corrosion and ensure smooth operation.
5. Elevate the fan assembly above the shaft and gently lower the hub onto the shaft, ensuring the keyways are perfectly aligned. Take care that the key remains in place during installation.
6. Secure the Hub Retention Cap Screw firmly with the Lock Washer to ensure stable and reliable fan operation.
