Centrifugal compressors are the largest available compressors, offer higher efficiencies under partial loads, may be oil-free when using air or magnetic bearings which increases the heat transfer coefficient in evaporators and condensers, weigh up to 90% less and occupy 50% less space than reciprocating compressors, are reliable and cost less ...

In an oil-free compressor, the air is compressed entirely through the action of the screws, without the assistance of an oil seal. They usually have lower maximal discharge pressure capability as a result.
The oil-free air compressor is an innovative device that has revolutionized the air compressor industry. It is a type of air compressor that operates without the use of oil lubricants. Instead, it utilizes specialized water or coatings such as PTEE, to reduce friction and wear within the compressor.
The oil-less (or oil-free) system has more technical development such as they do not require oil for lubrication. oil-less air compressors are also lighter and more portable than oil-lubricated models but require more maintenance.
Oil-free compressors operate without oil in the compression chamber, which eliminates the contamination with oil in the downstream compressed air.
An oil-injected air compressor works by injecting oil into the compression cavities of the unit. This does two things – it helps seal the unit (thus, reduces pressure drops caused by escaping air) and provides cooling (because compressing air produces heat that must be dissipated). With an oil-free air compressor, the air is compressed ...
An oil-free air compressor is an air compressor that doesn’t use oil for lubrication in the pump’s compression mechanism. Instead, the mechanical components are typically coated with a permanent lubricant material such as Teflon.
