"duster" = HFC-134a = tetrafluoroethane = the correct low pressure gas; what most Japanese GBBs run on.

However, a lot of "air in a can" is actually = HFC-152a = difluoroethane = slightly lower pressure and bad for a number of seals. Don't use it.

The can will always say either tetrafluoroethane or difluoroethane somewhere on it.
