The phenomenon of water mixed with compressed air output of Hitachi air compressors is a common problem, affecting compressed air quality and system performance. Water in compressed air can cause many serious consequences such as rusting equipment, reducing lubrication efficiency, and reducing product quality. Below, Minh Phu would like to share with you how to overcome the above phenomenon.
Maintenance GuideLow pressure in the Hitachi air compressor air system
Pressure in the Hitachi air compressor system is the result of supply and demand of compressed air. When you use a lot of compressed air, the pressure will drop. The control system will try to compensate by generating more compressed air. When you use less compressed air, the pressure increases. When the pressure increases to the maximum set level for the air compressor, the compressor will stop generating air. At this time, the machine will switch from load mode to idle mode. So what causes low pressure in the air compressor system?
Maintenance GuideHandling when Hitachi air compressor cannot start
At the beginning of your shift, you press the start button for the air compressor but do not see the signal that the machine is operating. Now you need to check the causes surrounding the air compressor. Below are the causes as well as common remedies for the above condition.

An air compressor not reaching the set pressure is a condition in which the air compressor cannot create enough compressed air pressure as desired, affecting operating efficiency and productivity. Air compressors work on the principle of sucking air in, compressing it and pushing it out. Setting pressure is the compressed air pressure that the air compressor needs to achieve after the compression process. When the air compressor does not reach the set pressure, it means the actual compressed air pressure is lower than the set level. The article below Minh Phu will show you the causes and how to fix this problem.
Maintenance GuideOil glue phenomenon in Kobelco air compressor
Air compressor overcurrent is the phenomenon in which the current flowing through the air compressor motor exceeds the allowable level. This can lead to many serious consequences such as: engine fire, component damage, and reduced operating efficiency. The article below Minh Phu will share with you the causes, solutions and measures to prevent overcurrent in Hitachi air compressors.
Maintenance GuideWarning symbols on Kobelco air compressors that you need to know
A very common error that often occurs in air compressors is that the machine has high temperatures when running. Especially in the summer or in hot weather conditions. Heat is a direct result of the gas compression process. During the process of compressing air, it will become hot, the heat needs to be removed to keep the compressed air quality at the right temperature level. In the article below, Minh Phu will share with you how to overcome the above situation.
Maintenance GuideOvercome the phenomenon of oil in compressed air
When using an air compressor, you will encounter a few cases where oil is mixed in the output compressed air, affecting the quality of your output compressed air, especially for manufacturing industries that require the quality of compressed air to be clean, dry and completely free of oil vapor. The article below will share with you the causes and how to fix the above phenomenon.
Maintenance Guide10 Common Mistakes During Maintenance and Repair of Hitachi Air Compressors
Suction valve oil leakage is a common problem with air compressors. This only happens when the machine stops or when the air compressor is unloaded. So why does this phenomenon happen, where is the problem? Through this article, Minh Phu will share more clearly with you about this issue.
