Oil Free air compressor although lubricating oil is not used to participate in the compression chamber workregular drainage is still required.. This is because during the compression process, the water vapor in the ambient air will condense into liquid water in the cooling stage and accumulate at the low point of the gas storage tank, condensate separator and pipeline.
Why does condensate produce?
No matter whether it is oily or not, as long as the air is compressed and cooled, it will follow the principle of “dew point”-high temperature and high humidity air will be compressed and heated, and then cooled by the aftercooler, the relative humidity quickly reaches 100%, and the excess water condenses into liquid water.
What are the risks caused by undrained water?
- Accelerated gas tank inner wall corrosion (especially carbon steel tank)
- cause damage to internal water accumulation of pneumatic tools, valves or precision equipment
- breeding microorganisms and polluting gas sources (especially for medical, food and electronics industries)
- reduce system pressure stability and gas quality
how to drain water scientifically?
It is recommended to manually open the drain valve at the bottom of the air storage tank and drain it once a day. If it is equipped with automatic drainer (such as floating ball type or electronic timing type), the operation reliability and the smoothness of the drain outlet should be checked regularly. In high humidity environment, the drainage frequency needs to be increased accordingly.
