There's a ventilation system running straight into the safe room.

The ventilation.

Uh, it's ventilation.

The air handling system inside it

like this building here environments that have mechanical ventilation systems that include filtering, heating and air conditioning.

We'll need coolant for the air support system.

This room has fine ventilation.

They've gone up the ventilation shaft.

and the gas will travel up that shaft and filter through the ventilation system that leads directly to parliament.

Those are for, like, you know, ventilation.

I think it came in the ventilation shaft.

You need some better ventilation back there, amigo.

But back above ground, these raised ventilation grates for the subway system show that solutions can be both functional and attractive.

Therefore, the system must be essentially airtight in order to capture air.

He added an air duct system that can cut through the maze.

Now, before we go in there, the power is back on, so the ventilation and filtration system should also be back on.

The ventilation is off, Tony. We're all burning up.

I was shocked to see that they're not using a central air conditioning system every window has an air conditioner in it.

The diaphragm and intercostal muscles are a pumping system that facilitates this air exchange.

I'm here because the faa reported some irregularities in their air traffic control system.

I've turned the ventilation up to keep the outside out.

Spent eight hours in a sealed Room, no ac, no ventilation.

Air

Air.

So, here is our plane with passengers, luggage on board, entertainment system, air condition, and whatnot.

We blocked them off at night so that they got no ventilation.

There's got to be something else, a ventilation shaft, a heating duct.

Air speed

Oxygen Air

Air Pressure

Air pressure

Air conditioner.

Air raid?

The air...

Air Force.

Fresh air.

Air Force!

You see the sunbeams coming from the ventilation ducts and the train approaching.

This is the natural posture of a man sitting, squatting for ventilation purposes.

The air conditioner isn't taking in enough air.

Call in air support! Call in air support!

Remove the seats. The plane still catches fire. Remove the air conditioning system and repeat the whole thing.

So the very first thing we wanted to do in this building was look at the air system.

Andrea is a living air filter that absorbs toxic gasses from air, contaminated indoor air.

The ventilation in the room was bad since all of the windows were closed.
