The impeller, motor, volute duct, and motor base make up the majority of it. The 10 rearward curved arc blades that make up the impeller are specifically soldered between the front and rear discs. The complete fan is secured to the motor’s extension of the shaft end, which is mounted to the motor base. Separately fastened to the two sides of the volute is the motor base and the air collection device. On the outlet of the volute, the flange is supplied to connect with other parts, such as an air duct. The anti-corrosion classes range from C3 to C5-M as well.
