NJF The NJF series of aluminum alloy hollow cooling tower fans are meticulously engineered for optimal performance in cooling towers, presenting a spectrum of unique benefits compared to conventional fan models. These blades are specifically enhanced for ultra-quiet operation while delivering superior airflow and pressure capabilities even at reduced speeds. Crafted from premium aluminum alloy, the fan's skin is seamlessly infused with pigment, ensuring uniform distribution throughout its structure. Each blade is securely connected to the robust fan hub through a heavy-duty galvanized iron ring, integrally molded with every fan blade, ensuring durability and strength. Adjusting the fan's pitch is a breeze—simply loosen the hub attachment hardware to rotate the blades, allowing for precise pitch optimization and maximal horsepower efficiency.
Exceptional Transmission Efficiency: Designed with aluminum alloy airfoil blades, these fans boast high transmission efficiency, ensuring optimal performance and energy savings.
Featherlight Design: Constructed with high-strength aluminum alloy materials, our fan is remarkably lightweight yet robust, offering ease of installation and maintenance.
Impeccable Balance: Precision-engineered fan blades are rigorously tested for weight matching and balance prior to delivery, and any necessary adjustments are made to ensure flawless operational equilibrium.
Enhanced Anti-Corrosion Capability: The advanced surface oxidation treatment process significantly boosts the fan's resistance to corrosion, ensuring longevity and reliability even in demanding environments.
TECHNICAL PARAMETERS
The fan blades are seamlessly connected to the hub via a robust, heavy-galvanized iron ring, which is integrally molded with each fan blade. Simply loosen the hub attachment hardware to effortlessly rotate the blades and set the perfect pitch. This allows for the most efficient use of fan horsepower, delivering optimal performance and energy efficiency.

FAN ASSEMBLY INSTRUCTIONS
The Newin NJF series of hollow type aluminum alloy fans are designed with convenience in mind, delivered to you in an unassembled form. Rest assured, each fan blade and hub is perfectly matched to facilitate seamless re-assembly, ensuring that the re-assembled unit operates with precision.
a. Choose a spacious open area that comfortably accommodates the full diameter of the fan for a hassle-free assembly.
b. Position the fan hub 1 centrally within your workspace, ensuring that the blade sockets are readily accessible for a smooth installation process.
c. Insert fan blade 2 into a designated blade socket on the hub. For models where blades overlap at the hub, ensure the leading edge is tucked securely beneath the trailing edge of the preceding blade for optimal alignment.
d. Confirm that the blade shank safety collar is positioned inboard of the inner hub rim for secure installation.
1. Ensure absolute safety by locking out the cooling tower motor before commencing installation.
2. Thoroughly clean both the hub bore and the entire length of the driving shaft extension to remove any debris for a pristine surface.
3. Carefully insert the key into the keyway, ensuring the key's top remains slightly below the shaft's top by no more than 3mm. The key fits snugly across the width and must remain unaltered for a secure fit.
4. Post-cleaning, apply a generous coat of anti-seize compound to the engagement section of the shaft to prevent future seizing and ensure smooth operation.
5. Gently elevate the fan assembly over the shaft and gradually lower the hub onto the shaft, aligning the keyways precisely. Make sure the key remains in place during installation to avoid any slippage.
6. Securely fasten the Hub Retention Cap Screw with the accompanying Lock Washer to complete the installation, guaranteeing stability and durability.
