Should I trade steel 120's 1 for 2 AL 80'?

**Monkey** · 12th August 2007, 21:50

Guys I am new to transfilling ..... is it better for me to keep my steel 120' or trade them for 2 AL 80'?

I have a chance to sell my 2 Steel 120's and the money I can get can get me 4 AL 80'?

what is best for transfilling the Steel 19'???

Thanks

The math is simple on this. If you can get full 3500 psi fills of oxygen and of mix / dil then keep the 120s. If you cannot get 3500 psi fills of oxygen / mix/dil then dump em and get 4 80s ... now you have two 80s for oxygen (cascade) and 2 for dil/mix

The LP steels are 2400 psi bottles and even at 1800 psi in them you have 13 cuft which is more than enough for most square profile dives.

I can get a full 3500 on O2 and my Dil....21/35... but I only have 2 steel 120's... so if I have one for 02 and one for 21/35.... i don't see how this is a better set up than 4 AL 80's....

but so I have all the info on the table... I already own 4 AL 80's so my fill bank as it stands now are 2 AL 80's and 1 Steel 120 for o2 and 2 AL 80's and 1 steel 120 for trimix 21/35

is it better to have 4 AL 80's for o2 and 4 AL 80's for trimix?

it would seem to me that 2 bottles is always better than 1 becuase I can cascade them... please advise

Thanks

then keep them all --- just use the HP tanks for your top up pressure --- more is always better .......

Based on what you have shared I would go with the extra psi that the steel tanks provide you.

Just my 2 cents....

I'll probably be leaving my booster at Pats for us to use after my Michigan trip.

If you fill all four of your 80s with source gas, will you still have more tanks to use for bailout in addition to those?

I ended out buying the large commercial cylinders from my gas supplier, and I just trade them out when I get new fills. I specifically made this deal with them so that I do not have someone claiming that I do not own tanks that are in my possession someday down the road. I keep the receipts to show that I originally started out with customer owned tanks. So, if anything ever happens, nobody can claim that I have "stolen" cylinders.

They will do the hydros on them when they become due without me having to pay for it, and it is less hassle on my part. However, I have to drive to the fill station with my tanks whenever I need new gas. That can become too much work for some. I find it worth it for myself.

This is good.... I really don't like the Hot Filling that Fill exspress does... so we can get our 02 with pat.

I will not be using AL 80's for bail out any time soon... I have AL 40's

and I would like to talk to you about getting bigger tanks... I will call you.
