Ventilation in metro and railway industries is primarily utilized for managing pollutants and controlling temperature under normal conditions and during emergencies such as fires. Essentially, having an appropriate ventilation system ensures the safe and proper transfer of air inside tunnels. Smoke and heat are the number one hazards in metro systems; therefore, a safe and standardized smoke extraction system assists passengers and staff in reaching a “safe refuge” quickly and easily. Moreover, in emergency situations, creating a smoke-free environment aids rescue teams and firefighters in their operations. Industrial ventilation equipment by FanIran facilitates rapid, safe, and easy smoke extraction for the peace of mind of passengers and quick access for emergency response teams to project locations.

Today, railway ventilation systems pose challenging conditions due to environmental factors and specific equipment requirements. Pollutants emitted by trains can manifest as emissions, heat, or sometimes particles. Typically, ventilation requirements to reduce pollutants and heat differ significantly from emergency ventilation, presenting multiple challenges in selecting ventilation equipment that must operate efficiently in both scenarios. Nearly all equipment utilizing electrical power generates some heat and must be ventilated underground using a combination of natural and mechanical ventilation. Under normal operating conditions, the piston effect of trains may suffice for adequate ventilation, and natural ventilation may maintain conditions even when trains are stationary. However, during periods of operational traffic or in the event of an incident, mechanical ventilation becomes essential.
