Customizable Speed Control Negative Pressure Fan with Belt for Optimal Ventilation

An exhaust fan with belt is a useful ventilation device with the following characteristics:

Functions:

• 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.

Features:

• 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.
