What You Need to Know About VB-SemiAIr
What is VB-SemiAir?
Active Technology is an advanced damping system that automatically adjusts your shock absorbers in real time, improving comfort, stability, and control while you drive.
How does VB-SemiAir improve my motorhome or campervan?
It helps maintain a level ride, reduces rear sag, and improves stability — particularly when carrying heavy loads or travelling long distances.
Can I adjust VB-SemiAir myself?
Yes — air pressure can be adjusted manually via the digital control unit
Does VB-SemiAir replace my suspension?
No — it works alongside your original suspension, providing additional support rather than replacing it.
Will it level my vehicle?
VB-SemiAir can help correct uneven loads and improve ride height, but it does not offer full automatic levelling like full air suspension systems.
Is VB-SemiAir right for me over full air suspension?
VB-SemiAir is a great option if you want improved comfort and stability at a lower cost. Full air suspension is better suited for those wanting maximum adjustability and automatic levelling.
