The oil content of oil-free air compressors is usually 0.01ppm. This is a very low oil content, so that the air produced by the oil-free air compressor during the compression process is almost free of oil. In some special applications, such as hospitals, laboratories, schools and other institutions, due to the higher requirements for air quality, it is more inclined to use oil-free air compressors.
In addition, there is a completely oil-free air compressor, which does not use oil lubrication, but uses resin material lubrication or other special lubrication methods. Such an air compressor does not contain any oil in the gas finally discharged.
The above information is for reference only. It is recommended to consult air compressor manufacturers or professionals in the field of air compressors to obtain more accurate answers.
There is a close relationship between the air pressure and the air volume (exhaust volume) of the screw air compressor, and this relationship is affected by many factors. The following is a detailed analysis of the relationship between air pressure and air volume of screw air compressor: 1. basic concepts Air pressure (exhaust pressure): refers to screw
In the textile industry, a field with extremely high air quality requirements, it is very important to choose a suitable oil-free air compressor. The water-lubricated oil-free air compressor produced by Shanghai Granklin Group is the ideal choice to meet this demand. Granklin Group, with its deep
The maintenance cost of the oil injection screw air compressor varies due to many factors, including the brand, model and the size of the air compressor. The following are some considerations about the maintenance cost of oil-injected screw air compressor: brand and model: different brands and models of oil injection
When choosing an air compressor, gas consumption is a crucial consideration. For application scenarios that require 8 cubic meters of gas, the water-lubricated air compressor produced by Shanghai Granklin Group is undoubtedly a wise choice. Shanghai Granklin Group as a company in
The slow gas charging speed of the oil-free air compressor may be caused by the following factors. It is necessary to ensure the efficient operation of the equipment through system investigation and maintenance: 1. The air intake system is blocked The air filter is used as the first barrier for air to enter the compressor. If it is not cleaned or replaced for a long time, it will be
Description of the service life of the air compressor The actual service life of the air compressor is affected by multiple factors such as the use environment, operating frequency, maintenance, etc., and it is difficult to summarize it through a single age. Granklin water lubricated single screw air compressor adopts oil-free design, through the junction
In industrial production, air compressors are indispensable and important equipment, especially in scenarios where gas pressure and stability are strictly required. Among them, the medium pressure screw air compressor is favored because of its excellent performance and wide range of applications. However
Medical compressed air plays an important role in the medical field. It is a key component of many medical equipment and surgical operations. The following are the main uses of medical compressed air: Power source: Medical compressed air is widely used as a motor for various medical equipment
Good or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor. But the oil-free air compressor is much more expensive and the maintenance cost is higher. If it is used
The difference between oil-free screw and micro-oil screw air compressor is mainly reflected in the following aspects: Working principle and structure: Oil-free screw air compressor does not contact oil at all during compression. There is no direct contact between its rotors, there is a certain gap, and dependent
