Assuming this can safely pump O2 (which i do not know), this seems like a heck of a deal. Haskels run on compressed air, and the cost of a compressor big enough to drive, say, an AG30 to rated pressure is significant (like $1K) by itself. Even used/rebuilt Haskels are going to run a couple thousand bucks. Plus, this is almost certainly far less noisy than a Haskel and compressor. I wear hearing protection when I use mine. Finally, a full set of spares and tools is a great bonus.

Andrew and I have never met, but if I didn't already own my Haskel and compressor, I'd give this a hard look for the price. Even if it's not safe for O2 but works for Helium it's probably worth it. O2 is fairly cheap. He, not so much.

Just my 2 PSIG.

Thanks. This unit is perfectly safe for O2. I've used it for years for that purpose. The main seals are Viton, a modern day replacement for the original leather seals. In terms of economics one would just need to add a set of whips, plug it in and you are off and pumping.

I have had a number of discusions with people concerned about the size of the booster. The dimensions listed above are for the shipping container which is much larger than the pump. The booster itself is only 10" wide X 31" long X 19" tall. The base is only 7 inches wide but the output regulator sticks out a little more making it a bit wider. It isn't small by any means but perhaps smaller than the shipping dimensions suggest. It is roughly the size of an AGT-15/30. Hope that clarifies things.
