Standard for oil content of screw air compressor

The oil content standard of screw air compressor is usually stipulated by relevant international, national or industry standards. The following is some specific information about the oil content standard of screw air compressor:

1. oil-injected screw air compressor:

   • generally speaking, the oil content of the compressed air of the oil injection screw air compressor is not more than 3ppm (that is, the oil content per cubic meter of compressed air is not more than 3 mg) is in line with the standard.
   • There are also more stringent standards, such as the "Air Compressor Pollutant Emission Standard" (GB/T 3785-2006) stipulates that the oil content in the air discharge of the screw air compressor should not exceed 5 mg/m & sup3;.

2. Oil-free screw air compressor:

   • according to the ISO 8573-1 industry standard, the oil content of the compressed air of the oil-free air compressor must be less than 0.01 mg/m & sup3;, in order to reach the CLASS 0 level, is recognized as oil-free compressed air.

Please note that different screw air compressors may need to meet different oil content standards, and the specific standards should be determined according to the equipment model and application scenario. In addition, when using a screw air compressor, the oil-water separator, filter element and other components should be regularly checked and replaced to ensure the quality of compressed air and the normal operation of the equipment.

In general, the oil content standard of the screw air compressor is determined according to the equipment type and application requirements, and must be strictly observed to ensure the normal operation of the equipment and the quality of the compressed air.
