What Is 8 Bar High Pressure Oil Free Air Compressor?

The high-pressure oil-free air compressor is a machine used to protect against rain, cold, and wind and sand. It consists of a compressor host, a motor, a coupling, a piping system, a control system, electrical equipment, and auxiliary equipment.

How To Maintain Your 8 Bar High Pressure Oil Free Air Compressor

Drain the air compressor tank
Drain the air compressor tank according to the instructions because moisture is squeezed from the compressed air and will fill the tank and reduce the amount of air stored. Failing to regularly drain the air receiver will result in the tank rotting and contaminating the compressed air. This will eventually cause the compressor to become damaged and stop working.

Regularly inspect the power lead
Keeping an eye on the air compressors cable to see if it has become damaged due to wear and tear over time will help to keep the air compressor functioning properly. If there is any damage, it's important to stop using the compressor and call an electrician to ensure that it's safe to use.

Check the pressure
When the air compressor is running, check the pressure regularly and make sure its not too high as this could damage the compressor over time and affect its lifespan.

Check the compressor's behaviour
Regularly check your compressor to make sure it's working as it should. Irregular behaviour can signify a fault with the compressor so if your air compressor is displaying unusual behaviour, shut it down, unplug it from the mains and check it over or call a maintenance engineer.

Check for leaks
Have a look at the area around your compressor to make sure it's not leaking either when it's off or when it's running. If you find a leak, it's important to call in an engineer or fix the air compressor before you use it again.

Check the air filter
The air filter location varies model by model so it's important to check the exact location in the owner's manual for your compressor. If the air filter inside is made of paper or felt, it will need replacing once it shows signs of wear and tear. If it's a foam filter, you should be able to clean it out with soap. Make sure you let the filter dry out before replacing it and replace any filter that's damaged or worn.

Visually inspect your air compressor
Regularly inspect elements of your air compressor such as the hoses, valves, and seals for cracks or signs of wear and tear and make sure any fittings are still secure. If you find any wear and tear or damage, it's important to get it fixed or ask a professional to look at it to prevent any problems from becoming bigger and more costly.

Check the safety valve
Checking the safety valve of your air compressor is something you should do regularly. Before checking, make sure you're wearing safety glasses and then you can plug the unit in, allow it to run until it reaches its shut off pressure and then pull out the safety valve ring so the pressure is released from the tank.

Check the seals
The seals of your air compressor will experience wear and tear and will eventually need to be replaced. Depending on how much use your compressor gets, this can be between 2,000-8,000 hours of operation but some oil free air compressors can last for longer.

Advantages of 8 Bar High Pressure Oil Free Air Compressor

Oil-free air compressors mainly replace oil with water to achieve lubrication, cooling, sealing and other functions. The parts that need lubricating oil for lubrication in the whole process are replaced by water. It can be said that oil-free air compressors have no lubricating oil throughout the working process. Therefore, the compressed air does not contain oil and the gas quality is high;
High quality of compressed air: Oil-free air compressors can replace engine oil with water for lubrication due to their particularity. Coupled with the cleaning effect of water itself, a part of impurities and dirt can be cleaned during the operation of the air compressor, which reduces the probability of compressed air being contaminated and makes the compressed gas have a high degree of cleanliness;
Based on the characteristics of water lubricating oil for oil-free air compressors, the temperature during the compression process is close to the suction temperature. Secondly, the cooling performance of water is slightly better than that of the oil. Therefore, the temperature of the entire compression environment can be controlled to make it comparable to the suction temperature. The temperature is similar, reducing the occurrence of high temperature faults;
Because it is lubricated by water, there is no need for accessories such as oil and gas separators, oil filters, etc., which reduces this part of the expenditure for the enterprise. At the same time, the maintenance also eliminates the link of replacing the oil and the oil filter, which simplifies the maintenance steps.

How Do 8 Bar High Pressure Oil Free Air Compressor Work?

Drawing in air
The first step your oil-free compressor takes is to draw in outside air through an unloader valve and pass the air through a filter. The filtering process keeps dust and debris out of the unit. The valve opens to load the compressor, then closes. Once it closes, the compressor is unloaded and starts to run. At this point, the compressor does not draw in additional air.

Compression
The compressor element will compress the air and move it through the unit to cool it down. Compressor elements typically generate a lot of heat, causing the unit to operate at up to 180 degrees. This is much hotter than oil-lubricated compressors.

Intercooler cooling
After the air is compressed, pistons push it through the intercooler. Here, the air is cooled so the unit can further compress it. This also minimizes the risk of damage due to heat. The process of cooling may cause condensation, so your oil-free compressor may also feature a moisture trap.

Second compression
After the air is cooled, it returns to the compressor for a second round of compression. The high-pressure element will further compress the air, typically achieving a maximum pressure of 116 to 143 psi (pounds per square inch). This process generates even more heat, so cooling is again necessary.

Aftercooler cooling
When the air undergoes the second round of compression, it can reach temperatures as high as 150 degrees. To cool the air down, it enters the aftercooler. The air passes through a check valve on its way to the aftercooler to prevent backflow. Your oil-free compressor may also feature a dampener, which reduces vibrations caused when valves open and close. Once the air has been cooled, it is stored or used.

Monitoring
A pressure switch monitors how much air is left in the compressor. If the volume falls below a certain level, the compressor will turn on and rebuild more pressurized air for the tank. If the pressure switch fails, the compressor will not refill and will require air compressor repair.
