Compressors must be labelled as required and packed in specially designed corrugated boxes.
Before packaging, the compressor is evacuated, and then filled with industrial nitrogen at (0.049-0.088) MPa.
The product certificate should be attached to the packing box, and the product for retail should also be accompanied by the instruction for use and installation.
During transportation, it should be handled with care, and it is not allowed to be beaten, exposed to rain, exposed to the sun, and not allowed to bruise the compressor in the box.
