HOW OIL-INJECTED ROTARY SCREW AIR COMPRESSORS WORK
 
As the name suggests, there is oil injected in this type of screw compressor. But where is it
injected, why and how? Let me explain..
As said before, the screw element is the most important part of the air compressor. But it
can't function by itself. There are a lot of other parts that make up the air compressor.
 
How it works
Outside air
Air is sucked in by the screw element (air-end) through the air inlet filter. The inlet filter
makes sure that all the dust en dirt stays outside. It protects the screw element (which is
very expensive and can be damaged.
 
It's also the first step in making sure that the compressed air is clean: all the dust that is
sucked in will eventually end up in the compressed air system.
 
Load/unload control
Before the air enters the screw element, it passed the inlet valve or unload valve. This
valve opens and closes the air supply to the screw element.
 
When it's open, the compressor is in 'loaded' condition: it is actually compressing air and
pumping it into the compressed air system. When the valve is closed, is shuts off the air
supply to the compressor element: the motor and screw element are turning, but the compressor is not sucking any air in and is not pumping any air to the system.
