What does dual-circuit system in air suspension mean?

A dual-circuit system in air suspension means that there are two separate air circuits used for the air springs in the vehicle. Each air circuit is usually responsible for one side (left or right) or one set of axles (front or rear), so that the pressures in the air springs on each side of the vehicle can be controlled independently.

In a dual-circuit system, there are usually two separate control valves and one or two air compressors responsible for controlling the air supply and pressure in the air suspension. Each air circuit has separate lines and valves to control the flow of air into the appropriate air springs.

A dual-circuit system provides greater flexibility and control over the pressure in the air springs because the pressure on each side of the vehicle can be controlled independently. This allows the vehicle to be better balanced and stabilized, especially when cornering and on rough terrain.

However,dual-circuit systems tend to be more complex and expensive than single-circuit systems and require more maintenance and repair.
