Inert gas compressors compress gases that do not react with lubricating oils. With minor exceptions, the lubrication requirement can be suitably handled by the lubricant used for air compression.
In refrigeration compressors using ammonia as a refrigerant, synthesized hydrocarbon based lubricating oils are recommended because of their low solubility for ammonia.
