John Forbes mentioned: As an ex-diver, I would say that it wouldn't be a good idea to use the air from that compressor for diving either. I'd rather have oil on my sensor than oil in my lungs. In normal circs, air from a diving compressor should be pretty damn clean.
Yes, your right of course John, but I only use the tank to fill a precharged pnuematic air rifle, and had just had the fittings and hose assembled to enable me to do that. It was this hose that I thought would double nicely as a dust remover. Even so I was suprised to learn that the shop where I got the work done had left the contaminant in the hose. I was told that it would be done to "food quality" standards, so expected total cleanliness. Regards, Max
