What is the difference between oil-free air compressor and oil compressor?


Nowadays, oil-free air compressors are favored by many consumers, among which oil-free air compressors have many unique features and advantages. In fact, in general, oil-free air compressors do not contain oil at all. Oil-free is a completely oil-free air compressor. An air compressor lubricated with resin material is a fully oil-free air compressor. Generally speaking, oil-free air compressors have a small oil content. So, what is the difference between an oil-free air compressor and an oily air compressor? The following Copco has compiled relevant content to share with you.

difference between oil-free air compressor and oil-based air compressor:

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

2.Different service life: The oil-free air compressor adopts a heat-blocking piston, so that the bearing grease is no longer lost due to high temperature conduction and radiation, which greatly prolongs the service life of the oil-free air compressor. The oil-air compressor does not have a heat-blocking piston, and the sealing grease is easy to lose, resulting in dry grinding damage to the bearing and a short life of the oil-air compressor.

3.The working principle is different: the oil-free air compressor does not involve oil during operation, whether it is an oil-free piston machine or an oil-free screw machine, a large number of high temperatures will be generated during operation. If air compressor oil is involved, the high temperature generated during the compression of the air compressor will be carried away, thus cooling the machinery.

4.Different exhaust: The oil-air compressor is lubricated with resin material, and the exhaust does not contain oil. Oil-air compressors are oil-lubricated, so the exhaust contains oil.

The difference between an oil-free air compressor and an oily air compressor can be roughly distinguished from four aspects: material, service life, working principle and gas emission, so today's content will be shared, I hope to help you.
