A Semi-Transverse Ventilation System is designed to provide effective air circulation and ventilation in industrial facilities, tunnels, and large enclosed spaces. In this system, fresh air is supplied or contaminated air is extracted through a network of ducts, while the remaining airflow travels longitudinally through the space. This arrangement helps maintain proper air distribution, remove excess heat, control airborne contaminants, and improve indoor air quality. Axial Flow Fans are commonly used where high air volume is required at relatively low to moderate static pressure, while Centrifugal Fans are suitable for applications requiring higher static pressure to overcome duct resistance, filters, and other system components. The fan selection depends on the ventilation layout, airflow capacity, pressure requirements, and the nature of the industrial process. Semi-transverse ventilation systems are suitable for industrial buildings, manufacturing plants, underground facilities, and tunnel applications where controlled air supply and exhaust are essential for maintaining a safe and comfortable working environment.
