Oil Vapour in Compressed Air

The quantity of oil vapour in compressed air depends on: 

 * Type of oil [coolant] 

* End temperature after compression 

* Outlet temperature of the compressed air 

* Working pressure 

TWO-Stage Oil Separation Using:

Primary Separation Element.

and

Secondary Separation Element.

Not all Rotary Oil Flooded uses, two separator element type.

Oil Separator Tank design were use to provide better separation. Therefore only one piece of element is required.

 NOTE: 

Oil Vapour passes all air/oil separator elements 

That is, at temperature of 100 degree Celsius, up to 5 times more oil goes through than at temperature of 80 degree Celsius. 

 If you have a perfectly balanced air/oil separator, then the high oil consumption, due to high oil carry-over to compressed air could be: 

 * Oil return (scavenging) pipe is blocked 

* Oil return (scavenging) pipe too short, not of the correct length 

* Oil specification wrong 

* Oil vapour too high [due to high temperature] 

* Oil level too high 

* Air refine efficiency is bad 

* Too much oil foam
