I was in Global Dive today - and they've taken a consignment of second hand Luxfer 40 cu ft tanks.
These are a different size than then "standard" 40 cu ft, a bit shorter with a higher working pressure. They apparently started with 13 of them yesterday and only have 4-5 left.
Fully LAB'd - real LAB numbers, not SP.
I haven't checked the LAB register at ERMA to see whether these are approved for mixes other than air. Will check later and post.
Selling at the bargain price of $299. These will go quick, so give Andrew a call at Global on 920 5200 if you are interested.
