Compressed air oil content ppm and mg/cubic

The oil content of compressed air is usually expressed in ppm (parts per million) and milligrams per cubic meter (mg/m & sup3;), both of which are used to measure the degree of oil pollution in the air. Ppm is the unit of volume concentration, which refers to the ratio of oil volume to the total volume of air; mg/m3 is the unit of mass concentration, which indicates the mass of oil contained in each cubic meter of air. Both can be converted to each other through parameters such as air density, pressure and temperature, but the core points to the same indicator-the cleanliness of compressed air.

In medical, food, electronic semiconductor and other industries with strict air quality requirements, the oil content of compressed air should be controlled at a very low level to avoid oil pollution affecting product hygiene, equipment accuracy or process stability. For example, the gas supply of medical equipment needs to ensure that there is no oil residue, the gas used in food packaging needs to avoid oil contamination, and the production of electronic components needs to prevent oil particles from adhering to the product.

Granklin air compressor adopts water-lubricated single screw compression technology, realizes gas compression through the cooperation of single screw and star wheel, and replaces traditional lubricating oil with water medium to complete lubrication and cooling function. This design eliminates the risk of oil pollution from the source, and the output compressed air has a very low oil content (can be regarded as oil-free), which effectively meets the stringent requirements of the above-mentioned industries for clean gas. Whether it is a precision manufacturing scenario that requires high-purity gas or a special process that is sensitive to air quality, Granklin air compressors can provide reliable oil-free compressed air solutions to help the industry achieve safe and efficient production goals.
