Why are water-lubricated oil-free screw air compressors favored?

Compressors/air compressors are divided into oil-free air compressors and oil-injected air compressors (or micro-oil air compressors) according to whether lubricating oil is used to lubricate the entire air compressor system. Oil-free air compressors are divided into single-screw oil-free air compressors and twin-screw oil-free air compressors according to their structure. The twin-screw oil-free air compressor is dry and oil-free, and there is no lubricating medium between the rotors, so the exhaust temperature is too high, the specific power is high, and many disadvantages, so the single-screw is widely recognized in the market. So why do people generally accept water-lubricated oil-free screw air compressors? To sum up, it has the following advantages:

1. Larger displacement (air delivery)

The displacement of the single screw water lubricated air compressor can reach 0.8m³~50m³.

2. Higher pressure

The single-screw water-lubricated air compressor can compress and discharge the pressure up to 40 kg (which cannot be achieved by the twin-screw oil-free).

3. Higher efficiency, more energy saving

The single-screw water-lubricated air compressor is close to isothermal compression, has higher volumetric efficiency, and saves more than 15% energy than the two-stage compression dry oil-free screw compressor.

4. Lower noise, less vibration

The design of the single-screw water-lubricated air compressor makes its structure balanced and stable, with low noise and small vibration.

5. Real oil-free compression stainless steel air end

The single-screw water-lubricated air compressor main engine is made of 304/316 stainless steel, with a design life of 20 years and has a number of patented designs.

6. Clean and corrosion resistant

The interior of the single-screw water-lubricated air compressor is an all-stainless steel system, which can be used with confidence, peace of mind and worry.

7. Pure oil free

The single-screw water-lubricated air compressor does not have any lubricating oil inside, and there is no risk of oil pollution. It adopts imported self-lubricating bearings, and the main engine does not need to be lubricated for life.

8. Lower daily maintenance costs

The single-screw water-lubricated air compressor uses water as the lubricating medium, and only needs to replace the water filter element and the air filter element for daily maintenance. Low cost to use.

The above are the 8 aspects that are the advantages of the single-screw water-lubricated air compressor, and also the reason why the majority of users choose the single-screw water-lubricated air compressor.
