What is the average oil content of compressed air
The oil content in compressed air usually depends on the type and technical specifications of the air compressor. Generally speaking:
-
Oil injection air compressor: During operation of this type of equipment, lubricating oil will participate in the compression process, so the oil content in the compressed air is relatively high, usually in the3ppm to 5ppmbetween.
-
Oil-free air compressor: This type of equipment is specially designed to avoid direct contact between lubricating oil and compressed air, so the oil content in the compressed air is extremely low, usually lower than0.01ppm。
It should be noted that in practical applications, the oil content of compressed air may also be affected by factors such as equipment maintenance status and filtration system efficiency. In applications where higher air quality is needed, even if oil-free air compressors are used, additional filtering devices may be needed to further reduce the oil content.
