Not sure what you're asking.
If you want to know if it will run on air then yes, all markers work better on air than CO2. Some markers will only run on air but no markers only run on CO2.
Hope this helps.
has it got a regulator or an expansion chamber?
If its got the expansion chamber and running on air make sure you are dry firing when unscrewing tank, otherwise you could burst a burst disk in your tank.
CO2 is fast becoming a thing of the past. The mad temperature fluctuations we have here in the UK make it near-useless (and un-safe if your marker spikes).
Air is always the best option - and you can usually get air fills where-ever you got CO2 fills from.
