The Air compressor is an integral part of the air brake system of the long haul truck. It is used to recharge the brake system after every stop. The Air compressor provides the required pressure to make the braked wheels effective. A properly designed and well maintained on-board air compressor can ensure trouble-free, safe braking performance on all road conditions for a longer service life of both the vehicle and its components.

An onboard air compressor is used to power various auxiliary equipment on the vehicle including the service brakes by providing pressurized air. While traveling from one place to another truck drivers have to stop at intervals. This stopping and starting sequence further continues while going from one city to another city, which ultimately leads to brake system failure if not properly maintained. To avoid this problem, Onboard Air Compressor In Truck was introduced by Robert Bosch GmbH under Mannesmann brand name – Powerplus.

How To Choose the Best Onboard Air Compressor For Your Truck

Types of Onboard Air Compressors

The compressor is a positive displacement rotary pump that uses engine power to compress air. It comes in two types:

  • The belt drive system uses an auxiliary engine as the engine usually have greater horsepower than the actual requirement of the tractor so it is better to utilize this excess power by utilizing the belt drive system, that connects the pump with the main engine over a V-belt pulley, hence additional equipment can be avoided.
  • The shaft-driven system is also called a Hydrostatic System because an internal gear pump pressurizes oil under pressure and then this oil is transmitted to a hydraulic motor which gives the required power for running air compressor. While using a hydrostatic pump there are no chances of belt slippage there, hence is no chance of power fluctuation.

However, in most applications, it is belt driven with the auxiliary engine for the single track or with the prime mover itself when multiple trucks are connected in a road train.

How to install an ARB air compressor?

Steps to Follow While Mounting ARB Compressor

  • First of all, the area where you are planning to mount the compressor should be checked for its strength and also make sure that it is capable enough to bear the weight of the compressor.
  • Decide on an appropriate position depending upon your preference but remember not to obstruct any other control structures or cables present in that particular location because this can create a problem during operation time which may lead to serious injuries or malfunctioning.
  • The next step is drilling holes for mounting bolts at suitable locations around the compartment before fixing them into place with nuts and washers.
  • The compressor is now ready to be mounted with the help of slotted holes which will have to be screwed into place by using bolts-head and nuts for holding it in proper alignment throughout its range of motion.
  • Make sure that the area where you are mounting your Air Compressor is free from any moisture or dirt so as to avoid any kind of damage being caused to it due to rusting or corrosion because these are some very common problems that can arise if not properly taken care of especially when mounted outside on a truck bodywork which has direct exposure towards water or other harmful materials present in the atmosphere like dust or grime.
The capability of the Compressor

As the Air Compressor is a motor-driven device, it requires more power to produce greater air pressure and volume. The onboard compressors have the capability to run at low noise levels while increasing their efficiency with increased drive power. Their duty cycle can also be extended in case of higher ambient temperature conditions.

The need for RPMs These days there are various types of equipment available that will greatly help you in achieving your work requirements without any hassles which are available at extremely cheap rates when compared to what they would cost if brought from an outside source. Along with these devices also come along numerous advantages like enormous lower labor costs, shorter set up time required for installation, less amount of electrical wiring, etc. But perhaps one of the most important work tools that are available today is the air compressor which is used to provide power in order to run different equipment or tools that drive through compressed air.

The need for volume Air Compressors is perfect for those who require huge volumes of air at their workplace, as they can give you high flow rates and pressure at your desired location easily. They play a major role in providing a consistent flow rate and also can be used as a source of clean dry air as well as free from oil and other contaminants due to their inertness. This helps in achieving superior results while working with pneumatic tools and accessories thus enabling you to work more precisely every day.

Noise Level All

the commercial Air Compressors available today have a sound level of at least 85 decibels while some can even go up to 100 decibels which is extremely high for a standard environment, so it is necessary that you purchase a compressor that has reduced noise levels in order to maintain peace and quiet within your working area.

In-built safety features Many times accidents happen simply due to the lack of care from the user’s end or sometimes due to an unexpected accident that can take place anytime which can lead to disastrous consequences if proper precautions are not taken into consideration while using any product. But all these types of problems can be easily solved by making use of devices that have got specific automated systems built inside them like pressure switch cut-off features, thermal overload protection, etc.

Inverter Compressors

These compressors have a variable speed controller which helps in changing the speeds of the compressor automatically to match with the air tool’s operating speed so as to get uniform results every time, but they are a bit more expensive than the conventional compressors available out there in the market today.

Size of the Compressor

The size of the air compressor unit installed on your truck may vary as per the requirement and specifications required by your company, but it is very important that you need to ensure that you have got a system that has been designed keeping in mind the weight capacity of the body along with its horsepower availability. This will not only provide better performance from your Air Compressor but also increase its lifespan as well.

Built to Stay

Air Compressors are built to last with their heavy-duty construction and parts which makes them extremely reliable for any kind of mobile pneumatic needs. It is however necessary that you drain the tanks after each use so as to ensure that there will be no moisture or water left in them.

Benefits Of An On-Board Air Compressor

An onboard air compressor saves a lot of time and money as the on-road repairs can be completed quickly.

  • Usually, Onboard Air compressors are belt driven from a separate engine or prime mover engine thereby avoiding the extra cost to buy an auxiliary power unit. The size of these electrical devices usually depends upon the type of equipment being used with the vehicle in which the device is fitted.
  • An Onboard Air Compressor operates either by an auxiliary engine or powered by its own dedicated engine when multiple trailers are connected in road trains to provide compressed air for brakes & services applications for all vehicles which are equipped with it. This creates the availability of plenty amount of compressed air within a limited period after each stop without any interruption in the supply of compressed air
  • It is a cost-effective and efficient way to recharge the air after each stop.
  • The Onboard Air Compressor usually runs on engine power with automatic switches which avoid any overloading of the alternator, thus protecting it from overheating and damage.
  • It has a capacity range from 5 scfm (0.8 m³/min) to 25 scfm (4 m³/min).
  • A separate tank for storage is used instead of redirecting high-pressure air into the engine crankcase or back into the compressor case like other units do, which can cause oil contamination within the system. This storage tank is an additional advantage as it prevents the many problems associated with engine crankcase lubrication, which is also a safe way to operate.
  • The service brake system components are designed to keep them free from contamination by dirt and water so as to ensure a low wear rate of brakes and other parts.
  • In order to provide full boost pressure within a short time, Onboard Air Compressors have two or more compressors that run together in parallel where one compressor takes care of the first part of the boost while the second is complete it allowing short recharging times.
  • The backup feature adds safety during high-pressure air failures which may happen due to any reason such as loose connections or hose failure. This ensures continued serviceability during these remote occasions.
  • The compressors are also suitable for use with hazardous and corrosive gases.
