Manufacturing Process

Aluminum hub is fitted onto the motor shaft, with each blade inserted precisely into the hub slots and secured by controlled press-fitting.

Tapered bushings are installed to ensure perfect shaft-hub alignment and prevent vibration. Fastened with bolts, protected by a plastic end-cap.

The completed assembly is placed within a heavy-duty plastic safety shroud; support brackets are mounted, and shock-absorbing rubber seals are added for noise and vibration reduction.

A metal outer frame is fitted around the assembly, with electronic speed controller wiring connected and fixed with screws.

A metal safety grill guards the blade and motor area.

The fan undergoes powered test runs to verify smooth operation and safety.

After final checks, the unit is mounted on a wheeled base for mobility.

Long aluminum blades are punched with precise mounting holes via stamping.

L-shaped metal reinforcements are bolted to the blades, strengthening the structure and anchoring it to the motor arms.

Plastic wingtips are fitted to reduce drag and optimize airflow.

The ring-shaped lower shell is installed to seal the airflow path and enhance efficiency.

The assembled unit is hoisted to its operating elevation, with careful motor alignment to ensure optimal horizontal balance.

The system is run unloaded to verify balance and noise, ensuring safety and compliance.
