Is compressed air heavier than non compressed air?

    Yes. compressed air contains more air molecules than non compressed air. The weight of the molecules will weigh down and have more force pulling down from gravity than non compressed air, thus making it heavier.

    A cubic meter (or any fixed volume) of compressed air will have more mass than the same volume of non-compressed air. “Heavier” is hard to apply because you can’t really lift air by itself anyway. Each molecule of air will still have the same weight in both cases.
