On the difference and advantages between oil free air compressor and oil air compressor

At present, oil-free air compressors in the market are favored and reused by many consumers. Among them, the unique advantages of oil-free scroll air compressors are better than screw air compressors. What is the difference between them? Let's discuss it together!
Oil-free air compressors are favored by the market because of their own advantages. The lubricated air compressors using resin materials do not contain oil in the exhaust gas. It is a true oil-free air compressor. Its technical upgrades and characteristics have won the industry’s It is recognized that it can meet the special needs of many process gas. It is necessary to use a multi-stage separation filter device in the compressed air system or to pretreat the compressed air into dry air with a certain relative humidity; oil-high speed, high temperature The operating air compressor uses lubricating oil for lubrication, sealing and cooling, but it pollutes the compressed air. Although the oil-less, semi-oil-free, and all-oil-free machines developed by using self-lubricating materials reduce the oil content in the compressed air, they also reduce the service life of wearing parts, rust and cavities inside the machine and the piping system. The oil content of the press increases during the running-in period, wear period and off-load period. This is undoubtedly a threat to automated production lines pursuing high reliability.
At present, the dewatering equipment such as refrigerated dryers, heat-free regeneration dryers, and micro-heat regeneration dryers lose their dewatering function due to the oil in the compressed air; while the clean, oil-free gas compressed by an oil-free compressor is fully It protects the water removal equipment and reduces the additional capital occupation caused by the maintenance of the water removal equipment.
Using an oil-filled air compressor greatly wastes lubricating oil. Taking a 7.5KW high-quality oil-filled air compressor as an example, the monthly consumption of 5 kg of lubricating oil is low, and an extra 60 kg of lubricating oil will be paid in one year. Use cost. At the same time, in order to remove the oil in the compressed gas, it is necessary to use a high-efficiency oil filter, and the filter element needs to be replaced multiple times, which is also a large cost.
