Morphology

unpressured = pressured (transparent) = un + pressure + ed

Adding un- to the adjective 'pressured' directly yields the opposite meaning, and the technical air/gas sense is still recoverable from that base.

Etymology

Unpressured is made of the parts un- ('not') and press ('push'), so imagine air that is not being pushed into a space. An unpressured cabin is therefore one where the air is not kept at higher pressure, which is why such aircraft cannot fly as high without extra equipment.
