In the compressed air industry, Class Zero is used to show that air contains no ppm or oil. But a Class Zero compressor can still contain oil that leaks between the vents of the compressor blocks, gearbox or oil cooler. Class Zero Plus does not use lubricating oil, but operates on magnetic levitation. Here, there is no oil in the compressor at all. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
