bb1283 Posted April 3, 2019 Share Posted April 3, 2019 Maybe just more confidence but now I can breathe out but I'm using my nose only. I don't know if that is the difference or just took some practice. Quote Link to comment Share on other sites More sharing options...
bb1283 Posted April 3, 2019 Share Posted April 3, 2019 I wish I could try a demand valve though. I read that they work well too. Has anyone gotten one of those? I looked around and didn't find any. Quote Link to comment Share on other sites More sharing options...
zgreek Posted April 4, 2019 Share Posted April 4, 2019 Hey bb1283, I purchased a demand valve last year after the CB Conf., on the recommendation of another clusterhead. It works really well, and saves a lot of O2. https://www.diversalertnetwork.org/dive-store/?id=39 . I paid $205 last year, last week it was $192. Description: DAN Demand Valve w/6-foot hose sku is 611-3000. Good Luck 1 Quote Link to comment Share on other sites More sharing options...
CHfather Posted April 4, 2019 Share Posted April 4, 2019 zgreek, I can't get that link to work, even by copying it and pasting it. Quote Link to comment Share on other sites More sharing options...
zgreek Posted April 4, 2019 Share Posted April 4, 2019 Sorry for the mistake CHF, I just went online and typed in Dan in the address search/address bar, and got https://www.diversalertnetwork.org/dive-store/?. DAN DIVERS ALERT NETWORK I believe I had to use the sku # 611-3000 in the search, let me know how it goes. Quote Link to comment Share on other sites More sharing options...
bb1283 Posted April 4, 2019 Share Posted April 4, 2019 zgreek, Is that a 540 volve connection, or an 870 medical type? Quote Link to comment Share on other sites More sharing options...
CHfather Posted April 4, 2019 Share Posted April 4, 2019 bb', I should leave this to the experts, but I believe it will fit on any regulator that has a DISS fitting. Looking forward to being corrected if I'm wrong (see next post). Quote Link to comment Share on other sites More sharing options...

For example, it doesn't seem to come with a mask -- does a regular NRB or ClusterO2 mask fit on it?? Quote Link to comment Share on other sites More sharing options...
bb1283 Posted April 4, 2019 Share Posted April 4, 2019 Regarding the demand valve from DAN. I talked to someone there and he said the demand valve was a CGA 870, like medical oxygen tanks take, which is fine. That's what I have. I also have an old 540 but I cannot find oxygen for it.

zgreek Posted April 5, 2019 Share Posted April 5, 2019 To CHF, a 6' hose comes with the demand valve. I use the CB mask, without the bag, O2 flows only when you inhale. I also use a welding regulator (this can be opened to well past 40 LPM), I don't know my liters per minute, the regulator reads in PSI, when using the non demand valve set up, I opened the valve enough to fill the bag and keep it filled. With the demand valve I open the regulator enough to take in whatever amount of O2 I desire, again only when I inhale. Here's a pic of how I use the Demand Valve. bb1283, don't know which it is, maybe Racer1_NC will chime in, he's well versed in this. Quote Link to comment Share on other sites More sharing options...

Demand valves on med regulators need a DISS fitting. DISS fittings can be found on either type regulator but they are not standard on either type. I've seen welding regs that can support the demand valves as well. Quote Link to comment Share on other sites More sharing options...
bb1283 Posted April 5, 2019 Share Posted April 5, 2019 zgreek, That looks like a great set up. Thanks for the photo. Quote Link to comment Share on other sites More sharing options...
