How Many Blades Should Your Industrial HVLS Fan Have?

When choosing a large industrial fan, you would confuse and ask “How Many Blades Should My Fan Have?” Because you contact the fan manufacturers who have five blades and six blades, so you naturally want to ask this question!

As a member of industrial fan manufacturers, we can’t say whose fan is good, but let's talk about why we chosefivebladesfor the industrial HVLS fan.

1. To influence the air volume is size of the windward area not the number of blades.

The blade airfoil shape refers to the design principles of the propeller. The air flowrate of the blade is huge when the fan works.

2. No sympathetic vibration, safety and low noise.

With even number blades, two blades form a straight line, when one blade is affected by the airflow, the corresponding one will also vibrate, it is easy to damage the motor over time and also cause much noise. We apply five-blade design in odd number with asymmetrical axis, thus to eliminate effectively the magnet noise and vibration.

Steel inserting plate connects and locks tightly with the internal parts of blade,inserting plate is made of 45# high strength steel plate, with the feature ofdeformation resistance and fracture resistance in collision. Special inserting steelplate makes blade joint seamlessly to petiole with 3 pieces screws and coordinate with screw thread sealant. So it is much safety.

3. The lighter the fan is, the better it runs.

The weight of single fan blade is 7 kg, and total five leaves is 35 kg, which is more than 30% lighter than that of 6 leaves. When the large industrial ceiling fan works, the motor bears the torque of running blades and also support the weight of wheel and blades. So it is better to adopt aviation aluminum magnesium material with less the number of blades.

4. Low energy consumption with high air volume.

To generate 15,000 m3/min air volume,5 blades fan consume power energy with 1.29 kilowatts, but 6 blades fan need 1.5 kilowatts.

Besides, the aviation aluminum magnesium blade is integrated into the molding process with 5 extra reinforcement ribs inside, totally with the features of anti-corrosion, high strength, good toughness, fatigue resistance, bright surface oxidation, T6 heat treatment, easy to clean.

To sum up, the number of fans is not important, but considering safety, life span, energy-saving and other comprehensive points, five-blade design industrial HVLS fan is the best choice.
