What is the Air Suspension Air Compressor all about?

A device that compresses and pressurizes air. Used to inflate air springs.

An Air Suspension Compressor also called Air Compressor or Air Pump, inflates or deflates air spring bags as necessary. When a vehicle with air suspension drops below the factory-defined height, the air suspension compressor, also simply called an air compressor or air pump is activated and inflates the air bags or air struts.

Air Suspension Compressor Function

An air compressor is a machine that uses an electric motor or gas engine to power a device that sucks in successive volumes of air from the atmosphere, compresses (squeezes) each volume of air in a confined place to increase its pressure by making the volume smaller, and then transfers the high-pressure air to a receiver tank, The high-pressure air is drawn off from the receiver tank to power equipment.

Air compressors work

Air compressors work by forcing air into a container and pressurizing it. Then, the air is forced through an opening in the tank, where pressure builds up. Think of it like an open balloon: the compressed air can be used as energy as it’s released.

They’re powered by an engine that turns electrical energy into kinetic energy. It’s similar to how a combustion engine works, using a crankshaft, piston, valve, head and a connecting rod.

From there, the pressurized air can be used to power a variety of tools.

Application of air suspension compressor Systems

Air compressors have many uses, including: supplying high-pressure clean air to fill gas cylinders, supplying moderate-pressure clean air to a submerged surface supplied diver, supplying moderate-pressure clean air for driving some office and school building pneumatic HVAC control system valves, supplying a large amount of moderate-pressure air to power pneumatic tools, such as jackhammers, filling high pressure air tanks (HPA), for filling tires, and to produce large volumes of moderate-pressure air for large-scale industrial processes (such as oxidation for petroleum coking or cement plant bag house purge systems).[6]

Air compressors are also widely used in oil and gas, mining and drilling applications as the flushing medium, aerating muds in underbalanced drilling and in air pigging of pipelines.

Most air compressors either are reciprocating piston type, rotary vane or rotary screw. Centrifugal compressors are common in very large applications, while rotary screw, scroll,[7] and reciprocating air compressors are favored for small and medium sized applications.

Air suspension compressor Features

Air bag suspensions systems are a feature found on many luxury vehicles and SUVs. An air bag suspension system serves the same purpose as a standard suspension system, however, instead of using metal springs and liquid filled shocks, it uses a system of inflatable air bags filled with compressed air to suspend the vehicle off the ground.

One of the most important components of an air bag system is the compressor. The compressor is what supplies the entire system with the compressed air required to inflate the airbags and support the weight of the vehicle. Without the compressor, the entire air bag system would be left without air, and the vehicle would be left with an inoperable suspension

Advantages of Air Suspension Shock Absorber

Reduced noise, vibration and harshness

It’s much more comfortable for the driver – noise, vibration and harshness causes driver fatigue and discomfort, so if you can reduce this, it’s safer.

It’s easier on components – reduced vibration and harshness means better wear on other components in the truck. Trailers tend to last longer when on air suspension as the components don’t suffer as much vibration.

In short-wheelbase trucks it reduces the tendency to bounce over rough terrain when the truck is empty.
Improved fuel consumption

Some air suspension systems can optimise the ride height based on the speed of the truck and whether it’s laden or unladen. Unladen trucks usually sit higher because there’s less weight pushing the suspension down, but this is bad for wind resistance. A lower ride height means better aerodynamics because it reduces the wind resistance.

Because the suspension is better suited to the road surface, higher corner speeds can be achieved leading to time saving on routes with a lot of turns.

There is some trade-off in the fuel benefits in the form of a small amount of extra fuel used to run the air suspension compressor when needed.
More versatile on certain types of terrain

It is sometimes height adjustable – adjustability can help with different types of loads, plus air suspension sometimes comes with a ‘kneel’ mode to help with loading, and a ‘raise’ mode to help clear bumps and rough terrain.

It is sometimes adjustable for feel, enabling better drivability; a driver can choose a softer ride for motorway cruising, or a harder ride with better handling on roads which are more demanding.

Air suspension is more consistent and even for all wheels. Systems can ensure the truck is level side-to-side in the case of loads which are difficult to load evenly, and it can reduce body roll in corners. You can effectively eliminate suspension sag.

Because the suspension can be levelled with any load (using a height control valve), it allows a trailer to be built to a higher top and lower floor while maintaining consistency and ensuring that a trailer is never over-height.
More versatile for some loads

Fragile loads such as large panes of glass benefit from being carried on a truck or trailer with air suspension as there’s less risk of breakages. Other loads benefit from air suspension, too, meaning that a trailer becomes more versatile and therefore is less likely to be running empty.

Air suspension can increase the ability to transport some loads by creating better grip through levelling the suspension.
Improved tyre life

More effective suspension means less vibration that has to be accommodated by the tyre and this leads to better tyre wear.

Some air suspension can lift unused axles, further improving tyre life.
Better resale

Air suspension trailers have better resale value.
Less damage to road surfaces

While you don’t get any RUC benefits from running air suspension, there are actual benefits to the road network as it causes less damage to the road and bridges. Less vibration is transmitted into neighbouring buildings and structures.
Less load shifting and damage

When there’s less vibration through the suspension, it’s better for the load. While improvements in packaging and load restraint have reduced the amount of damage caused to loads on bumpy roads, the smoother ride of air suspension adds that extra level of cushioning.
