What is the primary function of a blowers driving belt in a ventilation system?

The primary function of a blower driving belt in a ventilation system is to drive the blower or fan. The belt is a key component that connects the motor to the blower, transferring mechanical power from the motor to enable the blower to operate. When the motor runs, it turns the belt, which in turn rotates the blower or fan blades. This rotation is essential for moving air through the ventilation system, allowing it to either exhaust stale air or supply fresh air into a designated space.

This mechanical link ensures that the blower operates efficiently and effectively within the system. Without the driving belt, the blower would not function, and as a result, the ventilation system would fail to provide the necessary airflow for maintaining indoor air quality and comfort. Other options, while they mention aspects of ventilation, do not accurately describe the specific role of the blower driving belt, which is solely to drive the blower or fan.
