Like its little brother the Air Canister/$, the Reinforced Air Canister/$ holds air and can be charged and discharged in a Charging Station/$. However, it has an increased volume of 6000mL and can be charged to 20 bar (it won't explode).
An interesting use for the Reinforced Air Canister/$ is as a bulk air storage device, in conjunction with an inventory such as a chest and a Pressure Tube/$ with a Charging Module/$. This can get even more interesting with an Aerial Interface/$ and a (vanilla) Ender Chest/$...
