What is the difference between oil-free air compressors and oil-lubricated air compressors?

Nowadays, oil-free air compressors are favored by many consumers

Nowadays, oil-free air compressors are favored by many consumers, and they have many unique features and advantages. In fact, generally speaking, oil-free air compressors do not contain oil at all. The completely oil-free air compressor is one that is lubricated with resin materials. Generally, the oil content in oil-free air compressors is very low. So, what are the differences between oil-free air compressors and oil-lubricated air compressors? The following popular science article has organized relevant content to share with everyone.

Differences between oil-free air compressors and oil-lubricated air compressors:

1. Different materials: Oil-free air compressors do not contain oily substances, avoiding contamination of terminal equipment by oil machines. Oil-lubricated air compressors contain oily substances in their materials, which can contaminate terminal equipment.

2. Different service lives: Oil-free air compressors use heat-insulating pistons, preventing the loss of bearing lubricating grease due to high temperature conduction and radiation, greatly extending the service life of oil-free air compressors. Oil-lubricated air compressors do not have heat-insulating pistons, making it easy for sealing lubricants to be lost, leading to dry wear and damage to bearings, resulting in a shorter lifespan.

3. Different working principles: Oil-free air compressors operate without oil involvement; whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature is generated during operation. If air compressor oil is involved, the high temperature generated during the compression process will be carried away, thus cooling the machinery.

4. Different exhaust: Oil-lubricated air compressors use resin materials for lubrication, and the exhaust does not contain oil. Oil-lubricated air compressors use oil for lubrication, so the exhaust contains oil.

The differences between oil-free air compressors and oil-lubricated air compressors can be roughly distinguished from four aspects: materials, service life, working principles, and gas emissions. Therefore, today's content will be shared, and I hope it can help you.
