What types of rotary screw compressors are there?
Oil-lubricated screw compressors
This variant is also sometimes called an oil-flooded compressor or an oil-injected compressor. The technical name, however, is oil-lubricated.
Oil-lubricated rotary screw compressors inject oil into the compression chamber. This oil cools and lubricates the compressor element. It also helps to remove the heat from the compression process, and aids in minimizing leakage in the compression chamber. As the next step up from piston technology, oil-lubricated compressors have as many varied uses as there are industries. This type of compressor is usually picked by users needing large volumes of medium pressure air.
