Process Air Fans are extensively utilized for ventilation, air convection, and de-dusting specially in the agriculture industry. Also, they can be utilized in industries like refrigeration, architecture, mining, textile, chemistry, flour, and feed processing plants. These are important exhaust systems in a modern rice mill. As the most critical components of a dryer, they remove the heated air by means of the drying system. They have higher pressure level as compared to normal fans and can control the resistance of deeper beds. However, the downside to that is Process Air Fans have lower airflow rates.
