A cheap and easy way out is to use a 12 volt compressor. You need to ensure that the plastic tube will fit over the valve connection.Or make it so that it does. This will work.
If you have a compressor (just the type which will pump up tyres and any cheap one will do) which plugs into the cigarette lighter connection in the dash, connect the compressor to that. You will need tubing which fits the exhaust on the compressor, and which will connect to the bowl of the mask. (Generally the mask piping will suffice.) Turn key to accessories, or start car, and the compressor will release air to the bowl holding the ventolin. We have used it while travelling if the children have needed a mask, or while away at a standing camp. The air flow from the compressor should be sufficient to atomise the ventolin. Let me know if you need more information .. hope this clears the mud :)
I'm thinking of when I'm on the road Wombat. Also, it would be handy to have when we have [ like last week] long periods of time without power. I have to use it 4 times a day. Too expensive to hire long-term.
