Morphology
The compound is compositionally transparent enough that a B1 learner who knows 'air' and 'gas' will infer it denotes a type of gas related to or derived from air. However, the precise technical sense (a manufactured gas with a specific composition and production process) is specialist knowledge not predictable from the constituents, so full understanding requires prior exposure or domain knowledge.
Etymology
The noun air gas comes from how people made this fuel in the past. They passed air over hot coal and the heat made a smoky gas used for light and warmth, so the name points to how it was made and its use as a 'fuel'.
