This oil analysis shows a dramatic rise in TAN (Total Acid Number) as well as an increase in iron and copper. This air end was in the beginning stages of failing. This customer waited too long between samples - 8 months. If done on a monthly basis, this problem would have been recognized far sooner and would have allowed us to protect this compressor from failure.

This oil analysis shows an increase in silicone (dirt). SPECO notified the customer and helped get new air and oil filters to that customer quickly. The following month’s oil analysis showed a dramatic decrease in the silicone level. By alerting this customer of the problem, SPECO helped that customer save their air end.
