Air separators ( first experience )

[JTplumbingservices]

Hi lads/ladies.
I came across my first air separator today on an open vented S plan system.
As I’m not clued up on them I was hoping someone could educate me a bit on how they work and where they fit into a system?
This seemed to be between the boiler and pump on the flow with the cold feed coming into it and vent coming off it.
Is this correct ?
Cheers

they like to block up and first port of call if the system wont re fill and waters in the f and e tank

Thanks mate , so what if any are the benefits of fitting one rather than having the feed and vent directly into the flow ?

They’re supposed to essentially beat the air out of a system by the way the water flows through them.

and normally find them on low head systems
