    Looking at buying an Alkin W31 - Any advice?

    Purchased! 2022 with 1.3 hours on it. Now to find some bottles and build a cascade. Looking for three 2400 PSI and three 3600 PSI or higher cylinders and a fill station.

    Great Dive shop in Bermuda?

    I’ve gone with Dive Bermuda and would say they are pretty great. Some of my favorite dives ever.

    Looking at buying an Alkin W31 - Any advice?

    Thanks Macado and everyone. I’m going to take the plunge and get the 31. Tracy, it’s a 2021 with low hours. I’m considering setting up a cascade but will try direct fills for a bit and see how that goes.

    Thanks. No shop here. Independent instructor that fills a few hundred 80s throughout the year

    Looking at buying an Alkin W31 - Any advice?

    I've read the older threads, but was wondering if any current W31 owners have advice on what to look for (i'm buying used) and what to expect (as far as components/filter life, upkeep, etc.) TIA -Dave

    Question What's wrong with a two-bottle cascade?

    I was contemplating a two-bottle system, say 400cf each, so figured between the two, they could fill (from 500 psi) 8-10 tanks. Then, I could refill the banks from the Oceanus and do another 8-10 AL80s in a day or two. Admittedly, pressure physics and math are neither in my wheelhouse or my...

    Question What's wrong with a two-bottle cascade?

    I've got 24 tanks, which is enough to run a 4-student class w/out having to refill. I'd have a few days between classes before having to fill the 80s again. Are you saying I'd need 6-8 bank bottles?

    Question What's wrong with a two-bottle cascade?

    Question What's wrong with a two-bottle cascade?

    Looking at springing for an Oceanus E1 compressor and see it's rated for a max two-bottle system. Just wondering what is the disadvantage in this? I'm an instructor and fill probably 200-300 63/80s in season. Thanks in advance.
