IE B019OIL SAMPLE ANALYSIS REPORT · THREE SAMPLES OVER 400 HOURS OF OPERATION
Compressor 2VM 100/8: oil cleared of metal on a running unit
Large wear particles left the oil, the oil cleared up, intensive wear stopped. 20× — largest metal wear particles in the oil, 100 → under 5 µm (Ukraine · 2006).

Key result
| EQUIPMENT | CONDITION AT START OF OBSERVATION | WHAT WAS MEASURED |
|---|---|---|
| Compressor 2VM 100/8 | Oil beyond any cleanliness class: chips longer than 100 µm, oxidized metal, intensive wear in progress | Oil cleanliness class per ISO 4406, size and composition of contaminant particles |
Before treatment and after 200 hours of operation
| WHAT IS IN THE OIL | BEFORE TREATMENT | AFTER 200 H OF OPERATION |
|---|---|---|
| Cleanliness class per ISO 4406 | Beyond class — extremely high contamination | 17/12 |
| Shiny (fresh) metal particles | 5–100 µm, large amount | up to 10 µm |
| Black (oxidized) metal particles | over 40 µm | up to 30 µm |
| Metal chips | longer than 100 µm | no more than 50 µm |
Before treatment the contamination was off the ISO 4406 scale, so no cleanliness class was assigned to the oil.
Before treatment and after 400 hours of operation
| WHAT IS IN THE OIL | BEFORE TREATMENT | AFTER 400 H OF OPERATION |
|---|---|---|
| Shiny (fresh) metal particles | 5–100 µm, large amount | under 5 µm, small amount |
| Metal chips and oxidized metal | chips longer than 100 µm, black metal over 40 µm | not reported in the sample |
| Overall assessment of the sample | Extremely high contamination, intensive wear in progress | Practically no contamination |
Samples were taken from the running compressor: between measurements the unit stayed in service.
