Synthetic Air Compressor Fluids
Keystone air compressor fluids make it possible to compress air over extended periods without oxidation or excessive deterioration, therefore allowing compressors to run cooler, cleaner and with lower energy costs. To satisfy the full range of compressor lubrication requirements, Keystone offers four lines of fluids, each based on a unique technology. They are: Diester and Polyalphaolefin Synthetics, Semi-Synthetic and Petroleum.
KSL® Synthetics deliver up to eight times the service life of conventional petroleum oils, often achieving 8,000 hours between fluid changes with fluid analysis.
A free air compressor fluid sample analysis kit is also available through your Keystone distributor. With sample analysis you receive a detailed "Lubricant Analysis Report" which provides answers and recommendations for maintaining optimum lubricant and compressor performance.
