Regulator pressure ???

[jamram]

hi everyone,

I'm using a Aqualung Titan LX and my friend is using Scubapro MK17 and both using AL80 3300 PSI, now we are planning to switch tank to Luxfer S106W with 4350 PSI. Now my question is do we need to change regulator or as is it will work on the the higher pressure tank ? or are there any special type of regulator for tanks having 3300+ and higher PSI ?

No problem with your regulator Titan LX, but it must have a DIN conector, not yoke.

An AL tank with a 4350 PSI service rating? Never heard of that, so I did a quick google search; looks like an interesting tank. I bet it's expensive, and I'm sure you know all about the challenges of getting a fill at that pressure.

Shouldn't be a problem for the MK17, but, as posted above, DIN. The modern SP yoke might hold fine, but I wouldn't try it.

According to TDL they also require hydro every 3 years- increased cost, and after 15 are junk. Why would you waste money on that? Pump a 95 to 3000 and you have a 108 and are more likely to get good fills. That 106 if you can't get full fills as many shops will not pump over 3000 will give you 73 cu ft. Luxfer should call that their "PT Barnum" tank.

Luxfer should call that their "PT Barnum" tank.

I like to think about it like buying a Maserati and driving it in a small town - you will never get it out of second gear.

What are the buoyancy characteristics of this tank? I don't think many dive shops can fill to that pressure? It's too bad because a smaller tank holding the same amount of air would be nice.

The only two regulator manufacturers I have been able to get written confirmation that the first stages are rated for reliable operation at 300 Bar/4351 PSI are Atomic and Aqualung/Apex:

Quoted from:
http://www.scubaboard.com/forums/tanks-valves-bands/333463-200bar-vs-300-bar.html

Update: I just received an E-mail confirming that all Aqualung that and Apex regulators with a DIN connector are rated and warranted for a 300 Bar/4,351 PSI inlet pressure. Basically, the Calypso is excluded — a DIN option is not available.

...all of our regulators with the exception of the Calypso are approved for use at 300 bar using the DIN connection. Our HP seat is the best in the industry and has been cycle tested at 300 bar and is completely stable and acceptable for use at that pressure. We do not have any available documentation other than the working pressures listed in the Owners Manual which are accurate.

thanks guys for all your feedback...anyhow we are still on the planning stage on switching to higher PSI and all your inputs will be a big factor/consideration in our decision making on our upgrade.

@Akimbo thanks for sharing the email.

....just wondering WHY the interest in such a tank ? You're never gonna get a fill to anywhere near that pressure anyway...not to mention the fragile nature of the tanks and their added expense ???

hi,

honestly i'm looking for a way to have a longer bottom time also forgot to mention that i'm in Jeddah...most diveshops i check out here can fill up high pressure tanks up to 4350 psi.
