First I want to know why all the stores near me label a can as "Compressed Air" when in actuality it is not air.
Specifically, they sell canisters that contain extremely flammable "1,1,1,2 Tetrafluororethane, Petroleum Hydrocarbon".
The compressed air is not fake, even though other substances exist in the can.
Tetrafluoroethane is required in the cans of compressed air to remove the moisture from the compressed air.
I think the petroleum hydrocarbon is required for the propellant in cans of compressed air.
