Medical air compressor is dry oil-free or water lubrication

The choice of medical air compressor is one of dry oil-free air compressor and water lubricated oil-free air compressor, which scheme will be better.

I need to talk about the advantages and disadvantages of the two schemes in order to better choose a suitable medical air compressor.

the advantages and disadvantages of dry oil free screw air compressor:

advantages: it has been put into the market for nearly half a century, and most of the imported brands have been relatively mature.

Disadvantages: As the technology has been relatively long, the congenital technical defects existing in itself cannot be changed (the structure of the whole machine is complex, the rotating speed of the main engine is as high as 9000~18000 r/min minutes, the working temperature of the main engine is as high as 200 degrees, the main engine has large leakage, large noise, low efficiency, high energy consumption, complicated operation and high maintenance cost).

the advantages and disadvantages of water lubricated oil free screw machine:

advantages: After summarizing the congenital structural design defects of the dry oil-free screw compressor, the advanced oil-free screw compressor technology developed and put into the market in the past ten years. The host and piping system are made of 304 stainless steel or copper alloy. The main engine speed is 2980 r/min minutes, the main engine working temperature is less than 50 degrees, the water sealing efficiency is high, the operation and maintenance is simple, the maintenance cost is low, and the noise is low.

Disadvantages: some water lubrication host shell using copper alloy material, corrosion resistance is poor. Although advanced water lubrication technology is also the main development direction of oil-free screw compressors, a large amount of capital has poured into this industry, resulting in a large number of low-quality immature products flowing into the market in the past two years, causing unnecessary losses to users.

In the choice of air compressor, to meet the requirements of the project as the first, easy maintenance, low failure, high cleanliness of compressed gas.

The medical industry must not have any sloppy, water lubricated air compressor in the forefront of air cleanliness, for the country's medical, chemical, food and other high gas requirements of the industry to provide oil-free air.
