Things to pay attention to when purchasing large industrial fans

1. The number of fan blades is generally an odd number to reduce the occurrence of resonance;
2. Whether the motor is integrated into the machine. The integrated machine reduces the load and impact on the motor and has a long service life;
3. The design of fan blades and wings should refer to the design principles of helicopters, and the materials should be corrosion-resistant and have a longer service life;
4. The advantage of double bearing design is to prevent oil leakage, the reducer no longer bears gravity, prevent shaking, protect gears, and increase service life;
5. Install protective devices properly.
