What an interesting project. That compressor that they use in their system, well I have a very similar 12v compressor I use for inflating tyres. What interests me is the Stanceworks system used two high output compressors yet Audi, Mercedes, Range Rover etc only use one and I have often thought the compressor was the weakest link in the system
I will take a picture of my tyre inflator later and post up
Here is the Stanceworks
