The special fan blade shape of the fan makes it self-cleaning to achieve higher efficiency. The fan blade is made of Krupp self-cleaning stainless steel material by stamping and forming. The air volume is large, no deformation, no break, no ash, beautiful and durable. Stainless steel thickness: 1.2mm, surface finish: BA

The motor has domestic motor and Siemens motor for customers to choose. It can be customized according to customer's needs voltage and frequency. The domestic motor is added with phase loss protection device. When the power supply is out of phase, the power is off. The motor is protected by IP55. Insulation class: F level.
