These fans provide unparalleled benefits, setting them apart from the competition. With blades engineered for whisper-quiet performance, they deliver optimal airflow and pressure efficiency even at reduced speeds. The fan's skin is composed of high-quality aluminum alloy, uniformly infused with pigment for consistent distribution across each laminate. Each blade is securely fastened to the fan hub with a robust galvanized iron ring, meticulously integrated into each blade's structure. Adjusting the blade pitch is a breeze—simply loosen the hub attachment, rotate to the desired angle, and unlock the full potential of the fan's horsepower.
High transmission efficiency: Experience top-tier performance with aluminum alloy airfoil blades designed for exceptional transmission efficiency.
Light weight: Crafted from high-strength aluminum alloy, these fans are remarkably lightweight yet incredibly robust.
Good balance: Precisely engineered fan blades ensure superior balance, having undergone rigorous testing for weight matching and stability before reaching you. Every fan is finely tuned for optimal running balance.
Anti-corrosion ability: Enhanced longevity with advanced surface oxidation treatment, significantly boosting the fan's resistance to corrosion.
TECHNICAL PARAMETERS
Engineered with precision, each fan blade is seamlessly connected to the hub using a robust heavy-galvanized iron ring, integrally molded with every fan blade. This design allows for effortless adjustment; by simply loosening the hub attachment hardware, blades can be smoothly rotated to your desired pitch, ensuring the optimal use of fan horsepower and delivering superior performance.

FAN ASSEMBLY INSTRUCTIONS
Crafted with meticulous expertise, Newin's NJF series hollow type aluminum alloy fans are delivered in an unassembled format. The precision-matched fan blades and hub guarantee seamless reassembly, ensuring perfect alignment and performance.
a. Choose a spacious and open area that can accommodate the expansive fan diameter, allowing for safe and easy assembly.
b. Centrally position the fan hub 1 within the work area, ensuring accessibility to the blade sockets for a streamlined assembly process.
c. Carefully place fan blade 2 into a blade socket on the hub. For fans with overlapping blades at the hub, ensure the leading edge is positioned beneath the trailing edge of the preceding blade for optimal aerodynamics.
d. Verify that the blade shank safety collar is positioned inboard of the inner hub rim to maintain safety and functionality.
1. Ensure the cooling tower motor is securely locked out for safety before proceeding with installation.
2. Thoroughly clean the hub bore and the driving shaft extension along the entire length of the key, removing all debris and contaminants.
3. Insert the key into the keyway. Ensure the top of the key is positioned slightly below the top of the shaft by no more than 3 mm. This precision fit must remain unaltered across the width to maintain structural integrity.
4. Post-cleaning, apply a generous coat of anti-seize compound to the engagement portion of the shaft, facilitating smooth engagement and preventing future seizing.
5. Carefully elevate the fan assembly above the shaft, gently lowering the hub onto the shaft with keyways aligned. Confirm the key remains stationary and does not slide during installation for a secure fit.
6. Secure the installation by affixing the Hub Retention Cap Screw along with the Lock Washer, ensuring robust retention and stability.
