Often on high points of steam heated Shell&Tube heat exchangers etc. I've seen a vent specified to allow air and other non condensables to vent.

e.g. this sketch

What's this device (I mean the one labelled "Air vent") in practice? It doesn't seem like a regular steam trap. Or is it? Or just a weep hole? But that'd constantly bleed steam.

In general, how is venting of steam enclosures achieved.

Ah! That must be what I need.

Thanks!
