Water content in outlet air of oil-free screw air compressor

The water content of the outlet air of oil-free screw air compressor usually does not exceed 80ppm (the water content per cubic meter of gas does not exceed 80 mg)If post-treatment equipment such as a dryer is installed, the water content can be further reduced to below 5ppm, and the pressure dew point can reach-40℃ to-70℃. The following is a detailed description of the water content of the outlet air of the oil-free screw air compressor:

When the oil-free screw air compressor itself is in normal operation, the water content of its outlet air will be affected by many factors, such as environmental humidity, the cooling effect of the air compressor, and the working status of the automatic drainer. However, if it meets national and industry standards, the water content of its outlet air generally does not exceed 80ppm.

In order to further reduce the water content of the outlet air of the oil-free screw air compressor and meet the production process with high quality requirements for compressed air, post-treatment equipment such as dryers is usually installed. These equipment can effectively remove moisture from compressed air, reducing the water content to below 5ppm, and at the same time, the pressure dew point can reach-40℃ to-70℃, thereby ensuring the dryness of compressed air.

Does the oil-free air compressor need drainage?

The oil-free air compressor also needs to be drained. The working principle of an oil-free air compressor is mainly to compress the inhaled air through mechanical components such as pistons, screws or turbines, and then output it as high-pressure gas. During this process, since the air itself contains water molecules (especially in humid and rainy […]
