Why bus and coach clutches are often air assisted?

Bus and coach clutches are often air-assisted to enhance their performance and reliability under heavy loads and demanding driving conditions. Air assistance provides a more consistent and responsive engagement of the clutch, reducing the effort required by the driver and improving overall control. This system also helps in managing the heat generated during operation, prolonging the lifespan of the clutch components. Additionally, air-assisted clutches can facilitate smoother starts and smoother transitions, contributing to passenger comfort.
