Ventilating a building simply replaces stale or foul air with clean, fresh air. Although the ventilation process is required for many different applications, the airflow fundamentals never change: Undesired air out, fresh air in.
Belt drive fans
Belt drive fans are better suited for air volumes above 2,000 CFM or static pressures above 0.50.” Adjustable pulleys allow fan speed and CFM to be adjusted by about 25%. High temperature fans above 50ºc (above 122º F) are almost always belt driven.
