If you have an empty Antargaz gas cylinder (purchased in the Benelux) and want to exchange it for a full one of the same type, you can now do it 24/7 at an Antargaz gas cylinder vending machine.
Return your empty cylinder to the vending machine, and you’ll receive a full one in its place. You pay for the contents of the cylinder only - i.e. the gas. The proof of deposit from your previous purchase remains valid.
