Comparative analysis of oil-free scroll air compressor and traditional compressor

There are big differences between oil-free scroll air compressors and traditional compressors in terms of working principle, performance characteristics, advantages and disadvantages, etc. Let’s do a comparative analysis below:

Working principle: Traditional compressors usually use the principle of reciprocating or screw compression, which requires lubricating oil to lubricate the impeller and the compression chamber; while oil-free scroll air compressors use the principle of scroll compression, and there is no contact between the impellers, so No lubricating oil is required.

Performance characteristics: Traditional compressors are usually noisy and vibrate, and require frequent maintenance and maintenance; while oil-free scroll air compressors have the advantages of low noise, low vibration, oil-free operation, and simple maintenance.

Advantages: Traditional compressors usually have a higher compression ratio and are suitable for high-pressure conditions; while oil-free scroll air compressors have the advantages of high efficiency and energy saving, dry compression, silent operation, high reliability and environmental protection.

Disadvantages: Traditional compressors need to use lubricating oil to lubricate the impeller and compression chamber, and the lubricating oil will pollute the product and the environment; while the compression ratio of the oil-free scroll air compressor is relatively low, which is suitable for medium and low pressure conditions.

In short, oil-free scroll air compressors and traditional compressors have different working principles, performance characteristics, advantages and disadvantages, and it is necessary to choose a suitable compressor type according to the requirements of the actual working scene. In terms of environmental protection, energy saving, stability and reliability, oil-free scroll air compressors have great advantages.
