Nitrox fills

[WIdiver_Paul]

Ahh, so if you're getting the premix blend, it's coming from a seperate tank, but the problem is they may or may not have a compressor that is 02 clean... I'm sure you'd be okay if that's the only dive shop you went in to, but if you got a dirty fill and didn't subsequently always get premix, there would be a PP blend going in to a tank that isn't 02 clean. Yikes! Trust me, you don't want that dirty air from their regular compressors anyhow. Just take off your SPG from your high pressure hose and take a look at all that crud if you've been using conventional air sources, you can definitely tell the difference between shops that have 1, 2 or 4 filters on their lines!!
