Difference between oil and oil-free air compressor

The difference between oil and oil-free air compressor is mainly reflected in the following aspects:

1. working principle

oil air compressor: need to add lubricating oil in the compression process. Lubricating oil not only plays a lubricating role, reduces friction, but also improves work efficiency. But at the same time, this may also bring the problem of incomplete oil and gas recovery.

Oil-free air compressor: no need to add lubricating oil when working. The air compressor produced by Shanghai Granklin Group adopts a new type of water-lubricated sealing technology, and through the optimization of the internal structure, the use of lubricating oil is completely avoided. This technology minimizes problems such as oil and gas recovery, thereby reducing the risk of environmental pollution.

2. scope of application

oil air compressor: more suitable for high pressure, high temperature, high power gas compression occasions, such as automobile maintenance, painting, rubber, mining and other fields.

Oil-free air compressor: It is more suitable for occasions with high air quality requirements, such as medical, food processing, printing, electronics and other fields. Because its compressed air does not contain oil, it can ensure the purity of the gas.

3. maintenance

oil air compressor: the need for regular replacement of lubricating oil and oil filter, in order to prevent the machine rust, failure and other problems. At the same time, the regular replacement of oil will also increase certain maintenance costs.

Oil-free air compressor: There is no need to add lubricating oil, but parts such as air filters and pressure regulators need to be replaced regularly to ensure the normal operation of the machine and avoid gas pollution.

Comparison of 4. advantages and disadvantages

oil air compressor:

advantages: high work efficiency, relatively low maintenance cost, and long service life.

Disadvantages: it will produce oil fume and oil pollution, which will pollute the environment; it is necessary to replace oil products regularly, which will increase maintenance costs; it is necessary to pay attention to safety during use, such as preventing oil fume from catching fire.

oil free air compressor:

advantages: environmental protection and safety, no oil fume and oil residue; low maintenance cost, because there is no need to replace the oil; high operational reliability, will not cause machine failure due to oil problems.

Disadvantages: relatively low in terms of efficiency, may not be able to meet all high-efficiency industrial application needs; the price is relatively high.

In summary, there are significant differences between oil-free air compressors and oil-free air compressors in terms of working principle, scope of application, maintenance, and advantages and disadvantages. When choosing, it should be weighed according to specific needs and conditions.
