The air supply
The air supply system consists of the engine air compressor, the air tanks, air valves and air lines. The engine air compressor supplies air for all the air equipment on the vehicle. The pressure delivered by the compressor varies. For several years, the air supply was maintained around 120 to 125 psi but on some new vehicles this has been improved to 135 psi. Dash gauges are present that will supply system pressure information but all vehicles have what we say to as a “pop off valve”. You can get the valve “pop off” when the system reaches the maximum air pressure.

About Air suspension and its uses
Pneumatic air struts, an air compressor, a solenoid valve block, an accumulator tank, and air lines that connect these components together.The air suspension strut is made up of an air spring that acts as the coil spring and a solenoid which provides the dampening effect by magnetically resisting the linear motion of the piston. The air spring is comprised of a pressurized rubber bag or “U-bellow” surrounding a cylinder-piston setup. In order to enhance durability, the bellow is made up of polyamide cord woven inserts surrounding an elastomer (i.e. rubber) that ensures the bellow remains air-tight. In order to improve the response behavior to external forces such as those encountered during cornering or while driving over bumpy roads, the bellows are often encased in an aluminum cylinder. Some air suspension struts have an air reservoir attached to the air spring in order to have a sufficient volume of air necessary to satisfy comfort requirements without increasing the diameter of the strut. This is often done in the rear struts of Audi vehicles in order to maintain a large boot space.

A series of body level and acceleration sensors feed information into a control module that in turn instructs the accumulator, compressor, and valve block to move air around accordingly.

About Air Springs & Air suspension compressor
HongGu Air Suspension Compressors burnout is one of the more frequent air suspension problems encountered by drivers. Burnout occurs when the air suspension compressor becomes inoperative from overuse caused by a leaking air spring or other component. By establishing partnerships with the leading Suppliers. These high-quality compressors are tested qualitative facilities and then most are fitted with application-specific components such as brackets, wiring harnesses, relays and integrated dryers to provide a fast, flawless, Plug-n-Play installation.

HongGu Air Springs, air suspension strut/ air shock absorber, air suspension compressor pump undergo extensive testing on HongGu-owned vehicles. Air springs feature state-of-the art, multi-ply air bladders manufactured by industry-leading rubber companies . The air springs are assembled, tested, and packaged using ISO-certified quality management principles. These Air Springs last longer, are easier to install, and provide unparalleled ride comfort and durability.

What is an air suspension shock absorber
The air spring shock absorber is mainly used to suppress the shock when the spring is shocking and the impact from the road surface. While it is inlet, although the shock absorbing spring can filter the vibration of the road, the spring itself will reciprocate, while the shock absorber is used to suppress such a spring jump. The shock absorber is too soft, the body will jump up and down, and the shock absorber will bring too much resistance to hinder the normal work of the spring. During the modification of the suspension system, the hard shock absorber is to match the hard spring, and the hardness of the spring is closely related to the vehicle weight, so the heavier cars generally use a harder shock absorber. Apparatus in contact with the shocking crankshaft, is used to counter the twist vibration of the crankshaft (i.e., the phenomenon that the crankshaft is turned by the impact force of the cylinder is flicked).
