How to remove water from air compressor

Air compressor in addition to moisture methods are mainly the following:

1. cold and dry water removal:
   • principle: Use compressed air to enter the cooler to make its surface temperature drop below the dew point, and the water vapor condenses into water droplets, which are then discharged from the drain.
   • Features: Simple and low cost, but the water removal effect may be affected by temperature and humidity.
2. Hot dry water removal:
   • principle: After the compressed air is heated, the water vapor is condensed into water droplets through a heat exchanger and discharged.
   • Applicable scenarios: deal with high temperature, high humidity of compressed air, in addition to water effect is good, but the cost is higher.
3. Adsorption water removal:
   • principle: Adsorbents (such as silica gel, molecular sieves, etc.) are used to adsorb moisture in compressed air. After the adsorbent is saturated, the moisture is released by heating or decompression.
   • Features: Suitable for low temperature environments and does not require external energy, but the cost and maintenance of the adsorbent may be higher.
4. Pressure pendulum water removal:
   • principle: Separate water by setting pressure changes.
   • Applicable scene: Suitable for occasions with low moisture content.
5. Membrane dehumidification:
   • principle: the use of polymer membrane material adsorption, effective separation of moisture and other impurities in the air.
   • Effect: It can not only improve the working efficiency of the air compressor, but also extend the service life of the equipment.

In addition, water removal can be assisted:

• install a drain valve at the lower drain outlet of the air tank of the air compressor to regularly drain the accumulated moisture.
• The moisture in the compressed air is treated by filtration to further improve the dryness of the air.

To sum up, there are many ways to remove moisture from the air compressor, and the appropriate method should be selected according to the specific application scenario, budget and effect requirements. In actual operation, a variety of methods can also be combined to achieve the best water removal effect.
