nonpressurized
Open to air
Not maintained at higher-than-ambient pressure.
Aircraft cabins are pressurized to simulate lower altitudes; nonpressurized compartments like cargo holds lack this protection.
The term applies to any container or space that doesn't hold pressure above its surroundings: a nonpressurized fuel tank, nonpressurized spray bottles use pump action instead of aerosol.
