Compressol H 68 is a compressor oil based on highly refined base oil, naturally resistant to aging. The addition of highly effective additives provides the following properties: Low carbon formation tendency, Good oxidation stability, Good corrosion protection, Good anti-wear properties, Low volatility. Compressol H 68 is recommended for the lubrication of reciprocating compressors and for drip lubrication of rotary vane compressors. Both of these compressors can experience high final compression temperatures. Due to its high quality, longer oil change intervals can often be achieved.
