Air compressor exhaust oil content standard

Air compressor exhaust oil content standards may vary due to different air compressor types, uses and industry standards. Generally speaking, for ordinary air compressors, the oil content in the exhaust should not exceed a certain limit to ensure the quality of compressed air and the normal operation of the air compressor.

In China, the national standard stipulates that the liquid oil content in compressed air shall not exceed 5 mg/m & sup3;, and the oil vapor content in compressed air shall not exceed 0.5 mg/m & sup3;. For micro-oil air compressors, the oil content in the outlet air shall not be higher than 0.01 mg/m & sup3;. For oil-free air compressor, it is generally believed that the oil content is 0.01ppm, while the oil content of the general screw air compressor is about 3ppm. But in fact, the oil content of the air compressor is below 5ppm, which can be called a high-quality oil-free air compressor.

In addition, different applications and industries have different quality requirements for compressed air, so there will be different oil content standards. For example, some industries with high compressed air quality requirements, such as the food, pharmaceutical, and electronics industries, may require exhaust gas oil content of less than 1 mg/m & sup3; or lower.

There are also some special types of air compressors, such as the water-lubricated oil-free air compressor of Shanghai Granklin Group, which adopts advanced water lubrication technology and does not need to use lubricating oil, thus avoiding the impact of oil and gas mixture on air quality. The exhaust oil content standard of this air compressor is far lower than that of conventional screw air compressor. Under ideal operating conditions, the exhaust oil content can be close to zero.

In general, the specific air compressor oil content standards should refer to relevant national standards and industry standards to ensure the normal operation of the air compressor and the quality of compressed air. At the same time, the maintenance and use of the air compressor will also affect its exhaust oil content, so it should be maintained and inspected regularly.
