Favorite Sorb

cedricverdier · 2nd June 2005, 08:14

Hi,

A recent thread from Andy Mumford made me thinking about a poll regarding the most favorite sorb for rebreather divers.
It's not only a matter of brand but also the reasons of this choice: is it the price, the availability, the efficiency, the convenience, the recommendation of the manufacturer/instructor, etc?

I personaly use Sofnolime 797 rather than anything else as I found it to be the most efficient sorb on the market (it's a personal opinion). Nevertheless when I travel, I sometimes use Spherasorb as it's cheaper and more readily available. But I can't get the same time out of it.

Cheers

sofnolime 8-12 just because i can get the time out of it... price is the same as 4-8 and gives me another hour or so, so why not

I am going to try and get Intersurgical to provide us with some test data, as far as duration 99.9% of my dives are well within safe limits so it has never been an issue that the duration is slightly lower than 797 the benefits far outweigh that extra 10% of scrubber duration.

Cheers,

whaddya want chris, I've got a pile of data somewhere.

Key points;

797 has an absorbency some 1.2 times higher (measured in co2/kg) than spherasorb.

Spherasorb claims a better packing structure than 797, which would imply a lower WOB and hence lower CO2 production from WOB. I've seen no TEST DATA to support this.

Spherasorb has a better resistance to physical churn, which reduces its dustyness.

So the big question that leaves is, does the Sphera reduced WOB offset its lower absorbence?

Finally, Spherasorb is cheaper than 797 by about 40% (disclaimer, I looked up this price about 8 months ago).

Sodasorb 6-12, easiest to get and least expensive absorbant around here.

Thanks Zak, speaking from my personal experience the sphera packs a lot better and requires less tapping than 797 to get it settled WOB is noticably different and there is significantly less dust. I always err on the side of caution regarding duration so I have yet to be concerned with the lower absorbence.

Sperasorb - much less dust than anything else I've used. I hate dust.
