The fan blades are stamped and formed from Krupp stainless steel, which is dust-free, beautiful and durable. The special blade shape design makes the air volume large, no deformation, no breakage, and makes the air volume the same way.

Excellent motors and Siemens motors are available. The voltage and frequency of the motor can be customized. Specially designed fans for automobiles are presented in the phase loss protection device, turn off the power supply, and when the power is in short supply, it can self-power off. The motor is rated IP 55 and the insulation class is F.

The fan pulley is made of die-cast high-strength aluminum-magnesium alloy with reduced weight and complete impeller blades. Stiffener pulley design. Eliminate internal stress, improve its own stiffness and stability, and will not break.

The fan bearings are waterproof for double row bearings, so water cannot enter. High intensity, low noise and maintenance-free.

The push-pull mechanism can open the shutters, ensuring low air resistance and high air volume. When closed, it is windproof, rainproof, and dustproof. It is processed by injection molding with 100% raw materials of high-quality nylon. The fastener push-pull mechanism is all copper rivets, which are not rusty and flexible. The guide rod is made of 304 stainless steel, which ensures high strength, no rust and reduced friction.
