Conference rooms are built big. Like in hotels, or conference centers.
But not everyone wants a big room if they only have 100 people in the audience. And they don’t want to pay for a room that can hold 600 people, when they are only gonna be clumped up in like 1/3 of the room or whatever.

So conference rooms are built in a way they can be subdivided. By airwalls.
Next time you are at a conference, look for tracks in the ceiling. Like a metal channel with a slot running through it.
Or look for a wall made up of 1m sections.
That’s airwall track & airwall.
You run them along the track until they hit another bit of wall, stick an Allen key in the end of them, and wind down a soundproofing seal that also locks the wall in place. Then you run out another, and so on, until there is a wall.

Where the track meets the actual room walls, there will be additional tracking and full height doors that allow the wall to be manoeuvred and stored

Additionally, this seems to be a permanent piece of building works to create a corner in an air wall.
They’ve included an exit, presumably because that’s the only way to meet fire regulations within budget.
