Excess oil in a compressed air system can be detrimental both to the end products and to the system itself. Because this contamination can damage equipment, facilities face decreases in productivity or high maintenance fees.
Oil-rich environments also create breeding grounds for microorganisms. Particularly in the food and pharmaceutical manufacturing industries, the introduction of oil or microorganisms can cause facility shutdowns or product recalls.
When food is contaminated with industrial oil, it can impact consumer health or create a bad odor or coloring. If oil has impacted food packaging, it will then contaminated the food inside this packaging. One notable case was the case in Germany 1997 where an expert released findings of mineral oil inside sausages.
