What is the difference between water lubricated oil free air compressor and traditional air compressor

There are significant differences between water-lubricated oil-free air compressors and traditional air compressors in many aspects.

Lubrication method:

water-lubricated oil-free air compressor is lubricated and cooled with pure water, and the body is made of special medical grade stainless steel, which will never corrode.

Traditional air compressor usually rely on lubricating oil to cool, the body will have the smell of oil.

Cooling effect and temperature:

water lubricated air compressor system pure water has been circulating in the system, the system will automatically change the water at a set time to ensure the water quality, the body working temperature is not higher than 50 degrees, so the water in the body is not affected and scale problems.

The working temperature of the traditional air compressor is very high, exceeding 200 degrees, which directly affects the life of the cooling oil and the bearing.

Bearings and Efficiency:

the water-lubricated oil-free machine adopts imported special bearings, and there is no problem with direct water lubrication. The machine head has high efficiency, low noise and few bearing combinations.

Traditional air compressors generally use ordinary bearings, short life and high noise.

Energy consumption:

the water-lubricated oil-free machine sprays pure water directly into the body. Due to the high specific heat value of water, the compression chamber is almost in the ideal state of isothermal compression, which is the compression process with the lowest energy consumption.

The cooling oil of the traditional air compressor is about 100 degrees, the temperature of the compression chamber exceeds 200 degrees, and the temperature difference is relatively large, so the energy consumption is relatively high.

Maintenance and cost:

the water-lubricated oil-free machine body is directly connected to the motor, the speed is lower than 3000 rpm, there is no speed-increasing gear, the bearing life is long, and the maintenance cost is low.

The traditional air compressor body and the motor should be between the acceleration and deceleration gear. Because the speed is above 18000 rpm, the speed-increasing gear is required to accelerate, the bearing life is short, and the maintenance cost is high.

In summary, there are significant differences between water-lubricated oil-free air compressors and traditional air compressors in terms of lubrication methods, cooling effects, bearing types, energy consumption, and maintenance costs. These differences make water-lubricated oil-free air compressors have higher efficiency and longer service life in many applications.
