Oil-free air compressor comparison

Generally speaking, oil-free air compressors do not contain oil at all. Truly oil-free is the all-oil-free air compressor. The air compressor lubricated with water is the real oil-free air compressor. Generally speaking, the oil content of oil-free air compressors is very small. So, what is the difference between an oil-free air compressor and an oil-free air compressor? The following Copco has sorted out the relevant content to share with you.

Oil free air compressor with oil air compressor difference:

1. Different materials: The oil-free air compressor itself does not contain oily substances, which avoids the pollution of the oil machine to the terminal equipment. The material of the oil air compressor itself contains oily substances, which will pollute the terminal equipment.

2. The service life is different: the oil-free air compressor adopts a heat-resistant piston, so that the bearing grease is no longer lost due to high temperature conduction and radiation, which greatly extends the service life of the oil-free air compressor. The oil air compressor has no heat resistance piston, and the sealing grease is easily lost, resulting in dry wear damage to the bearing and short life of the oil air compressor.

3. The working principle is different: the oil-free air compressor has no oil during operation. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during operation. If air compressor oil is involved, the high temperature generated during the compression process of the air compressor will be taken away, thereby cooling the machinery.

4. The exhaust is different: the oil-air compressor is lubricated with resin material, and the final exhaust does not contain oil. The oil-air compressor is oil-lubricated, so the final exhaust contains oil.
