Compressol H 68 is a compressor oil based on very highly refined base oil, with a naturally high resistance to aging. The following properties are achieved by adding highly effective additives: Low tendency to carbon formation Good oxidation stability Good corrosion resistance Good anti-wear effect Low volatility Compressol H 68 is recommended for the lubrication of reciprocating compressors and for the drip lubrication of vane compressors. High final compression temperatures can occur with both of these compressors. Due to the high quality, longer drain periods can often be extended.
