The presence or absence of oil in an air compressor generally refers to the oil content of the gas discharged from the air outlet of the air compressor. Generally, the oil content of the oil compressor is relatively large, and the oil content of the oil-free engine is 0.01 ppm, so use this The oil content is used to distinguish between oil-free and oil-free air compressors. There is also a completely oil-free air compressor, which is not lubricated with oil, but is lubricated with resin materials, so the final exhaust gas without oil is called no Oil air compressor.

Advantages of oil-free air compressor:

First, the current dehydration equipment such as refrigerated dryers, heatless regenerative dryers, and microthermal regenerative dryers lose their water removing function due to the oil in the compressed air; and they are clean and oil-free after being compressed by an oil-free compressor The gas fully protects the dewatering equipment and reduces the extra funds brought about by the maintenance of the dewatering equipment.

Second, the use of oil-powered air compressors not only needs to change the lubricating oil but also regularly replace the oil filter. At the same time, in order to remove the oil in the compressed gas, an efficient oil filter needs to be used, and the filter core needs to be replaced many times. Is a big fee.

Thirdly, due to the high viscosity of the lubricating oil, the current degreasing equipment cannot be completely removed, so that the gas-free compressed air of the oil-free air compressor seems irreplaceable.

Fourth, the use of oil-free compressor to provide compressed gas to the outside will not greatly reduce the motor load due to the pressure loss caused by the oil removal equipment, and achieve energy-saving effects.
