Properties and Performance of Rotary Screw Air Compressor Oils

The performance, reliability, and maintenance cost of a rotary screw air compressor are heavily influenced by its oil. Both the condition of the oil while in service and the specific type of oil or base stocks used are critical to compressor operation and longevity. Compressor Original Equipment Manufacturers (OEMs) and oil suppliers offer a variety…

Flush Procedures for Rotary Screw Air Compressors

mechanical engineer

Oil-injected rotary screw air compressors are one of the toughest applications there is for any type of lubricant or coolant. But when you try to perform both critical functions with a single fluid, and continuously pump large volumes of reactive air and contaminants directly into it, it is no wonder that oil-related reliability problems are…

How Temperature Affects Oil Performance and Service Life in Rotary Screw Air Compressors

Rotary screw air compressor oils must maintain their ability to lubricate, cool, seal, clean, and protect compressor internals across a wide range of ambient and operating temperatures. From freezing cold start-ups to scalding hot full load operation, these variations in temperature cause both temporary and permanent changes to the oil’s physical, chemical, and performance properties.…
