What is Air suspension?

Air suspension is an interconnected air-operated component that replaces the so-called MacPherson strut suspension. The air suspension gives a huge advantage to increase driving comfort and keep the ground clearance constant, regardless of the load of the car. The air suspension allows the car to be at a higher or lower level. The air suspension control system consists of: 

-High performance air suspension compressor that supplies the entire system

-Valve block with solenoid valves, which is responsible for the supply of air at the right time to each of the four airbags

-Height sensors that measure every second and determine the required exact height of the air suspension in order for the car to be perfectly leveled.

-Air springs - rubber spheres / balloons filled with compressed air

-Electronic unit that takes care of the entire air suspension system, when and how to work





Modern cars, thanks to the air suspension, are much quieter and move with much lower vibration levels. This contributes to both lower levels of fatigue and driver discomfort and more comfortable passenger travel. More efficient air suspension leads to lower levels of body vibration, which in turn leads to less load and wear. on the tires. Usually in the highest class, the so-called premium class cars, air suspension is mounted on both the front and rear axles, thus a level of regulation of the whole car is possible. This in turn helps to drive on rough terrain and off-road, as the car could be lifted to overcome high obstacles. Conversely, the air suspension is lowered when driving at higher speeds, on a highway, for example. This contributes to lower drag, better aerodynamics, better stability, and lower fuel consumption. For cars that are T models, or so-called station wagon models, air suspension is mounted only on the rear axle. In this way, it is possible to tow heavier caravans and trailers, while maintaining the horizontal position of the body is guaranteed. The air suspension prevents the lower position of the rear axle. When the car is heavy, its rear does not lie to the ground and the front does not rise high. The air suspension ensures and guarantees the correct position of the headlights, as well as stability, safety, ease of operation and comfort.



Air suspension is usually used as an increase in comfort and safety in premium cars, but not only. Air suspension is also widely used in special purpose vehicles, such as ambulances, fire trucks, civil protection vehicles, roadside assistance, vehicles for the transport of people with disabilities and many others. In all of them, the air suspension allows for higher reliability under increased load. Such cars are usually equipped with heavier equipment, which in a spring suspension would lead to very rapid fatigue of the metal in the springs, reducing the ground clearance, which in turn leads to non-functionality and unreliability of special purpose vehicles. The air suspension allows the car to maintain a flat body position. The air suspension prevents the low position of the rear axle, also allows the correct positioning of the headlights. The air suspension improves stability, safety, comfort and ease of handling and maneuverability.




The care of the air suspension is of particular importance for its proper functioning. In general, the most susceptible to problems are the rubber parts of the airbags. In case of untimely detection and solution of such a problem or its neglect, it leads to problems in the proper functioning of the air suspension and subsequent replacement, except for the airbags and the air compressor. The air suspension system is multi-component and a problem with each component can lead to the failure of the entire air suspension. The care of the owners of cars with air suspension is also expressed by periodic inspections in the service. In the e-shop of, you will find everything you need to maintain the air suspension system of your car.
