When do I need a single-circuit system and when a dual-circuit system for air suspension?

The choice between a single-circuit system and a dual-circuit system for air suspension depends on a number of factors, such as the type of vehicle, the size and weight of the vehicle, the desired stability and control, and the intended use of the vehicle.

A single-circuit system may generally be adequate for smaller and lighter vehicles, such as station wagons or vans, because it is simpler and less expensive than a dual-circuit system while still providing sufficient stability and comfort.

However, a dual-circuit system is often used on larger and heavier vehicles, such as RVs, trucks or buses, because it offers greater flexibility and control over the pressure in the air springs, which can help improve ride stability and safety. For RVs in particular, a dual-circuit system can help balance the vehicle better and prevent sway that can result from uneven load distribution on the front and rear axles.

Overall, choosing the right system depends on individual requirements and preferences, and it is recommended that you consult with an experienced professional to find the best solution for your particular vehicle. If you have any questions, please contact us.
