Often referred to as “technically oil-free air”, this system relies on air cooling de- vices (e.g. refrigeration dryers) and several stages of oil removal with multiple com- ponents. A failure of any of these com- ponents or inadequate maintenance can result in oil contamination of a process. Therefore, with oil-injected compressors there will always be a risk of contamina- tion and the possibility of severe conse- quences for your business. Move up to a risk-free standard.
