The Tunnel Ventilation System (TVS) is an air management system used in the MRT Jakarta railway tunnels. The
TVS is divided into two subsystems: the Trackway Exhaust Fan (TEF) and the Trackway Ventilation Fan (TVF).

The Trackway Exhaust Fan (TEF) functions to remove hot air generated by train operations. It also serves as a
smoke extraction system in the event of a fire on the platform side. Meanwhile, the Trackway Ventilation Fan
(TVF) operates bidirectionally, meaning it can either extract air from or supply air into the railway tunnel,
depending on operational requirements and emergency conditions.
