Applications
RotorLub 8K-HT is engineered for Champion rotary screw air compressors running at elevated discharge temperatures. Note that the RotorLub 8000TH replacing it is thinner (60 cSt at 40°C against 67.1) and flashes 14 degrees lower, so call us before switching if you moved to 8K-HT because of a high discharge temperature problem.
