Screw compressors are the most commonly used in medium- and high-capacity industrial refrigeration applications, thanks to their high efficiency. Specifically, screw compressors with oil injection provide a nearly isothermal compression process, as the heat generated during compression is absorbed.

Oil-injected rotary screw compressors are a crucial component in many industrial applications, offering high reliability and efficiency in producing compressed air. These compressors are commonly used in manufacturing, automotive, construction, and other industries that require consistent air.

When the air compressor is in operation, the appropriate amount of lubricating oil sprayed into the compression chamber can form a good oil film between the rotors, which can effectively reduce the friction between the rotors in time. However, the sprayed lubricant increases the friction of the air.

As the name suggests, there is oil injected in this type of screw compressor (as opposed to oil-free screw compressors). But where is it injected, why and how? Let me explain.
