Horizontal And Longitudinal Negative Pressure Fan 380V for Fresh And Moist Air
Function and Performance:
This type of exhaust fan is primarily used to remove stale air, odors, fumes, and excess heat from a space. It works by drawing in air from one side and expelling it to the outside through a duct or opening.
The belt drive system allows for a certain degree of flexibility in speed control. By adjusting the tension of the belt or using a variable speed controller, you can regulate the fan's airflow output to meet the specific ventilation needs of different environments.
The exhaust fan with belt can handle relatively large volumes of air and is capable of generating significant air pressure to ensure effective ventilation even in large spaces or areas with obstructions.
Advantages:
One of the main advantages of a belt-driven exhaust fan is its durability. The belt can absorb some of the shocks and vibrations generated by the motor, reducing wear and tear on the fan components and extending the lifespan of the device.
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.
