What are the operating steps for drainage and antifreeze of oil-free lubricated air compressors.

1. To drain the water from the water purifier, the water inside the purifier needs to be drained first. This can be achieved by closing the inlet valve of the water purifier and then opening the drain valve to completely discharge the internal moisture. Please note that after emptying, the inlet valve needs to be manually closed to ensure that no more water flows into the water purifier during winter.
2. Drainage of water vapor separation tank

Next, it is necessary to open the drain valve below the water vapor tank to drain the accumulated water inside. The purpose of this step is to prevent the water inside the water vapor separation tank from freezing and causing equipment damage.

3. Drainage of radiator

Moisture can also accumulate in the pure copper cooling pipes of oil-free lubricated air compressors. To prevent water from freezing, it is necessary to loosen the plug below the radiator and drain the water from the pipeline. At the same time, in order to ensure smooth drainage, it is necessary to regularly inspect and clean the debris and dirt inside the radiator.

4. Host drainage

For machines below 37KW, the main drainage operation is relatively simple. Just find the two plastic transparent tubes located at the bottom of the host, unscrew the screws to pull out the hoses and drain the water from the host. If it is a model above 37KW, you can find a drainage valve in the pipeline near the water filter barrel and open the drainage valve here to drain the water.

Analysis of the advantages of oil-free lubricated air compressors!

1. High quality compressed air

Due to its special nature, oil-free air compressors can be lubricated with water instead of engine oil. In addition, with the self-cleaning effect of water itself, it can clean some impurities and dirt during the operation of the air compressor, reducing the probability of compressed air being contaminated and ensuring high cleanliness of the compressed gas;

2. Oil free air compressors mainly replace oil with water,

To achieve lubrication, cooling, sealing, and other functions, the parts that require lubricating oil for lubrication in the entire process are replaced with water. It can be said that oil-free air compressors do not involve lubricating oil throughout the entire operation process, so the compressed air does not contain oil and has a high quality of gas;

3. Based on the characteristics of water lubricating oil for oil-free air compressors

Make the temperature close to the suction temperature during the compression process, and secondly, the cooling performance of water is slightly better than that of engine oil. Therefore, the entire compression environment temperature can be controlled to be close to the suction temperature, reducing the occurrence of high-temperature faults;

4. Because it is water lubricated

Therefore, there is no need for accessories such as oil and gas separators and oil filters, which reduces the expenses of this part for the enterprise. At the same time, maintenance also eliminates the need to replace oil components and oil filters, simplifying the maintenance steps.
