About Semi Air
VB-SemiAir enables the suspension to be adjusted manually within specific limits. On a vehicle with leaf springs, an air spring is fitted between the chassis and the rear axle. This air spring supports the existing leaf spring.
VB-SemiAir is supplied as a two-chamber system, which means that the air springs are not connected to each other. The use of a dual chamber system allows left and right to be adjusted separately, enabling the vehicle to be levelled, even when it is loaded unevenly.
