An auxiliary air suspension system supports the existing suspension of the vehicle and enables the suspension to be adjusted within specific limits. Auxiliary air suspension systems are often added to vehicles that (regularly) carry heavy loads or sometimes have variable loads. An air spring is fitted between the chassis and the rear axle, which raises the ride height of the vehicle and generates greater spring travel. The auxiliary air suspension system therefore helps to increase the level of comfort and stability when travelling in your vehicle.
Our auxiliary air suspension system, also known as VB-SemiAir, is supplied as a two-chamber system. This means that the air springs are not connected to each other. The use of a two-chamber system allows left and right to be adjusted separately, enabling the vehicle to be levelled even when it is loaded unevenly.
We offer various different types of auxiliary air suspension system to suit your needs:
VB-SemiAir basic system
The VB-SemiAir basic system is a good option for vehicles that always carry a heavy load and that occasionally carry variable loads (the pressure can stay the same more or less all of the time).
The VB-SemiAir basic system is made up of two air springs, fasteners and two inflation valves. You pressurise the system yourself using an external air supply, such as a tyre inflator.
VB-SemiAir comfort system
The VB-SemiAir comfort system is a good option for vehicles that carry variable loads. The control panel with high/low switch lets you easily adjust the auxiliary air suspension system to the right pressure.
The VB-SemiAir comfort system consists of a VB-SemiAir basic system including control panel with two pressure gauges, two high/low switches and a powerful, heavy-duty compressor. The high/low switches enable you to raise or lower the ride height of your vehicle so that you can easily inflate the air springs. The pressure gauges give an accurate reading of the pressure (in bar) in the air springs.
The control panel for the VB-SemiAir comfort system is available in two versions:
The VB-LevelAir is a VB-SemiAir basic system with automatic level control. The system provides for greater ease of use: there is no need for the driver to worry about operating the system while out making deliveries. This prevents incorrect or improper use. VB-LevelAir ensures the vehicle is always at the correct ride height and that the system is at the right pressure. The rear of the vehicle leans less when loaded, which improves stability and driveability, and so contributes to enhanced safety whenever you are driving.
The VB-LevelAir system is made up of the VB-SemiAir basic system including a high-quality compressor box with air filter, air dryer, valve block, height sensor and an ASCU (Air Suspension Control Unit).
