Dolomann Air Compressor Automatic Drainer 23-PA-68


Dolomann's 23-PA-68 pneumatic automatic drainer of air compressor, which is suitable for all kinds of compressed air. The improved automatic drainer of air compressor has higher stability, larger drainer port and easier discharge of oil-water mixture. Easy installation, no need to use electricity, and has the function of automatically cleaning the water outlet, which is not easy block. High temperature and pressure resistance, acid and alkali resistance.

For pneumatic automatic drainer of traditional air compressor, the outlet valve is at the bottom of the pneumatic automatic drainer, as the density of oil is smaller than that of water, the oil will float on the water surface and not easy to discharge, so it is easy to cause the drain port to be blocked. The water outlet of Dolomann automatic drainer is at the top of the automatic drainer, the oil floats on the water surface will be discharged first and then drained water. So the water outlet will not be blocked. Moreover, the height of the pneumatic automatic drainer is lower than that of the gas storage tank, it can automatically drain water by using the high and low drop of the water level, without using electricity can save parts of the electric energy.


  • The large drainage outlet makes it easier to discharge oil and sewage in the air compressor.
  • The displacement is large, and the maximum amount can reach 500 liters per hour.
  • The pressure range used is from 0 to16 Bar.
  • The temperature range used is from 0 to 80 degrees.
  • The stability is high. It is the best choice to choose this automatic drainer if the air compressor will produce a lot of oil and water.
  • With automatic cleaning function, the water outlet is not easy to block.
  • High PH resistance, can contact with some organic solvents.
  • Metal products, resistance to high pressure environment.
  • The material is valve steel plate with high durability.
  • Easy installation, no power supply, more energy saving.


It is mainly used to remover moisture from air compressor, these compressed air are stored in the air tank after compressing the air. As the temperature of the air tank is lower than that in the cylinder, the water vapor of the compressed air condenses into water droplets, and lubrication oil often enters the air tank along with the compressed air, the water and oil must be removed.

Dolomann's automatic drainer can discharge the water and oil-water mixture in the air tank out the system, keep the pipeline of the air compressor unblocked, and finally enhance the service life of the air compressor.
