Which is better, oil-free or oil-free, screw air compressor

The difference between oil-free air compressor and oil-free air compressor

from the oil content point of view, the oil and no oil in the air compressor generally refers to the amount of oil content in the exhaust gas of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm, so the oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of resin material lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.

From a structural point of view, there is no difference between the bearings of oil-free air compressor and oil-free air compressor. But from the working principle, there are obvious differences between the two. Oil-free air compressor in the process of operation is not involved in the oil, whether it is oil-free piston machine or oil-free screw machine, they will produce a lot of high temperature in the process of operation, if there is oil air compressor oil participation will take away the high temperature generated in the process of air compressor compression, so as to cool the machinery.

But the oil-free air compressor does not have the participation of oil, and in the compression process also produces a lot of high temperature, how to solve the high temperature to ensure the normal operation of the machine? In fact, the oil-free air compressor uses a special high temperature resistant material called Teflon or molybdenum disulfide, which replaces the oil to solve the high temperature in the compression process of the air compressor, thus achieving the purpose of oil-free compression.

Oil-free air compressor is cleaner and more environmentally friendly than oil-free air compressor to some extent, so institutions such as hospitals, laboratories, schools and other institutions are very suitable for the use of oil-free air compressor, and these institutions also prefer to use oil-free air compressor.

Which is better for air compressor with oil or without oil

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 for purging, machining, manufacturing and power use, it is possible to choose an air compressor with oil and micro oil. Such as spraying, steel, electricity, hardware, mining, ceramics, textiles, machinery, etc. are widely used.

The head of the oil-free air compressor is cooled by lubricating oil. The compressed air discharged from the air compressor has a large oil content, but the oil content can be controlled within a certain range through filters and cold dryers, and the procurement cost is low. The gas demand of most factories; the oil-free head is not cooled by engine oil, with low oil content and high procurement cost. It is generally used in special industries, such as hospitals, pharmaceuticals, food processing, semiconductor industries, etc.
