S. starfish:
Since we had absolutely no idea what exactly had happened we did everythign we could think if including putting new filters on our compressor and checking out the tanks, can't be too careful with this sort of thing. Our air gets pumped in from the roof of our building so it's pretty fresh and the risk of having anything like paint fumes in there, unless someone was painting the air duct, is pretty much nonexsistant. I'm pretty sure that it was something from the car but the owner denies it. It did have to get an overhaul after breaking down a while later though, it's pretty old.
