Spinner II®Trial Results
Ingersol-Rand® KVS-412 Integral Gas Compressor

This is a 5 gallon pail of debris the Spinner II® oil cleaning centrifuge installation removed after 3000 operating hours on this natural gas powered Ingersol-Rand® KVS-412 integral gas compressor!

The material looks like coal! The Spinner II® centrifuge packs the material it separates out of the oil into a compact cake. When cleaned the collected material breaks off in chunks.

IF THERE IS ONE THING TO POINT OUT FROM THIS TRIAL, IT IS THIS;

All 40 POUNDS of this wear causing, additive depleting debris passed straight through the existing full flow filtration before is was trapped and removed from the oil by the Spinner II® centrifuge.

The patch test
shows the Spinner advantage!
The two slides to the left are 8 micron test patches of sump oils from two integral gas compressors at the same plant. Unit 4 is the compressor pictured above. Both compressors run the same oil brand, type and viscosity. Both compressors have the same full flow 10 micron nominal sock filtration. The above compressor has two bypass configured Spinner II® centrifuges for this trial.

After 3000 hrs of centrifuge operation, five ml samples of oil were drawn through these test patches, (the light patch has had a little MORE oil drawn through it than the dark patch). A comparison of color intensity can therefore be made to compare the relative cleanliness of the two oils from the two compressors.

Using this patch comparison which oil is cleaner?
Which FILTRATION system do you want in your engine?
The following are excerpts from a report on the above compressor entitled the
"Chemistry Survey of Centrifuged Solids from an Ingersol Rand KVS-412 Integral Gas Compressor"

Here is the FULL REPORT minus the pictures below.
Major Conclusions
  • The Spinner II ® Oil Cleaning Centrifuge effectively controls the very sizes of lube oil abrasives causing the most wear in heavy-duty low and medium speed engines.
  • Application of a centrifuge in the engine lube circuit provides a high performance complement to the full-flow engine lube oil filters, removing abrasives these filters miss, and resulting in longer component wear life and extending full-flow filter life.
  • Ferrographic analysis of the centrifuge solids can allow direct inspection of engine health, so catastrophic failures can be anticipated.
  • In excess of 32 % of the total solids removed by the centrifuges over the engine service interval were metal oxides of wear debris and externally ingressed contaminants.
  • Qualitative analysis demonstrates that the Spinner II ® Oil Cleaning Centrifuge removes contaminants shown to have significant adverse impact on engine life and lube oil performance. Virtually 100% of the solid deposit in the centrifuge has been shown to either increase engine wear or shorten oil life.
