Air condenser (Fallout 76)

The air condenser is a world object

Gameplay
The object consists of the air condenser unit itself, with a ventilation grill that connects with it. The condenser may become detached from the mount if collided with, (either via an object being thrown at it, or by running into it) or damage from projectile weapons.

Locations
Air condensers can be found on various buildings in Appalachia, and sometimes in certain interiors.
