Hello forum members,
We perform our compressed air tetsing twice a year, and in the last testing we found significant amount of ash-like and char-like soot.
The lab the we used indicates the established normal range as 0-60/cubic meter of air .Our result is approx. 200/cubic meter per each.
We use compressed air for blowing packaging containers before filling with the product, to remove possible foreign objects.
The question is what amount is harmful to ingest?
We replaced all the filters and cleaned all the compressed air system. I would like to know if it is safe to keep using the compressed air meanwhile we are waiting for the retesting?
Thank you!
