High Speed Rotor Negative Pressure Exhaust Fan Low Noise 370W 380V

High-Speed Rotor Negative Pressure Fan For Low Noise And Stable Performance

Advantages:

• Belt-driven fans often offer more power and airflow capacity compared to some direct-drive models. This makes them suitable for applications that require high-performance ventilation, such as industrial settings, commercial kitchens, and large warehouses.

• The ability to adjust the belt tension and speed allows for customization of the fan's performance, enabling it to adapt to different ventilation requirements and operating conditions.

• Belt-driven exhaust fans may be slightly more complex in design compared to direct-drive fans, which could potentially increase the risk of mechanical failures. However, with proper installation and maintenance, these fans can provide reliable and long-lasting ventilation.
