Ventilated fans are also used in laboratories to remove hazardous vapours and maintain controlled conditions. Agricultural facilities rely on them to regulate temperature and humidity for livestock or crop storage. By addressing the unique needs of various industries, these systems show their versatility.

Ventilated fans operate through the use of an electric motor that powers a set of blades or an impeller to facilitate air movement. This process involves drawing air from a designated area and expelling it to the outside or circulating it within the space, depending on the specific application and design of the fan.

The mechanism of air movement relies on creating a pressure difference. As the fan blades rotate, they generate airflow by displacing air molecules, effectively lowering the pressure in the area being ventilated and encouraging the movement of air. This principle is critical in ensuring the efficient removal of stale air, moisture, or contaminants.

The performance of a ventilation fan can vary based on several factors. The size and design of the fan blades, the motor's speed, and the overall construction of the unit all contribute to its effectiveness. In systems involving ductwork, the layout and resistance within the ducts can significantly impact airflow. The materials used in the fan and its housing also influence noise levels, durability, and efficiency.
