Help please, re Faber LP 85 buoyancy specs

[tlessard]

The TDL chart specs for Fabers are about right for fresh water, while the BS specs are accurate for salt water. I'm currently diving double LP108s with a CLX450 DS in fresh water with AL40/80 stages - using 2-3lbs of tail weight - no other lead required. Good tanks - but the paint does get scratched up pretty good moving through restrictions. I have also dove Faber LP85s and LP95s - all are great tanks with great buoyancy chars for fresh water.

The OP is asking why the TDL/Huron charts differ from Faber's own buoyancy specs (which really do seem atypical to me).

Ah... didn't see TDL listed specifically but it tends to be the most comprehensive at least.

The FX100LPDVB is just about the oddest tank going right now, even if you overlook the fact that it's named 100 when it only holds 80. Looking at the buoyancy specs, you'd swear that someone got them mixed up and reversed them, but Blue Steel and people who have actually tried them swear they are correct - they are serious floaters.

The fill pressure, 2640, is exactly what one would expect from a plus-rated 2400 psi LP tank. and and some sites even list them as that, but they not plus rated LPS - they are exemption tanks, manufactured under the same SP as the 3442 HP Fabers.

Apparently, Faber made them as a special lightweight, low cost steel to go head to head with the aluminum 80, but it didn't work out that way, and they are closing them out very cheaply. But anyone thinking of buying them should be sure they understand what they are getting - they are not just a slightly smaller LP85! - and can use a tank that positive.

Looking at BS's website (Cylinder Specifications), it looks like the poorly-named FX100LPDVB 80 cubic foot tank is the one I'm talking about (2lb positive full, 8lb positive empty), not your LP85s.

Yes, the specs. are correct. I verified them with Faber Italy. They are real floaters.

The Faber 7.01" or 8.02" diameter LP85s are much better for buoyancy if you want an LP tank.
