[PSUBS-MAILIST] scrubber fan

[Emile van Essen via Personal_Submersibles]

 Hi All,

http://export.rsdelivers.com/product/comair-rotron/bd48b7-030638/biscuit-dc-
radial-blower-425cum-h-48v/7396569.aspx
Such blower or similar makes just 50-55 Dba.
Reduce the noise further with air boxes and silencers.

Regards, Emile

Hi Alec,
Yes, I like it, small scrubber and just throw the rest out.  I have been
diving with the o2 and scrubber off.  I am starting to go deeper longer so
it is time to abandon that practise.  Gamma's original scrubber is beyond
simple, it is a super big noisy fan with an open top brass canister with a
screen at the bottom.  The NOISY fan pulls air through it.  The canister
holds enough absorbent for a 10 hr dive with two people.  Hmmm, maybe I will
go back to that with a new quiet fan.

 Yes, Snoopy's works
 just fine. It's just that I'm building a new sub, so  needed a new
scrubber. I wanted the human-powered option,  and since there's two people
that meant two small  scrubbers instead of one bigger one. Once the R&D is
done, printing out a second is relatively straight forward,  even if a very
slow process.
 
 I load the scrubber agent at the start of the  day and throw it out at the
end. It isn't a large  quantity, just 2 liters. Apart from the loaded
scrubber, I  carry two 2-liter soda bottles in the sub so that, in the
event of getting stuck, I would have refills. Having a small  scrubber and
refills means that I'm not throwing out  loads of unused stuff.
 
 Best,
 
 Alec

 efficient, why upgrade it.  Do you need to bag the scrubber  between dives
or do you remove the absorbent.  I am adding  a second scrubber and just
trying to figure out the best way  to go.  My current scrubber is sealed air
tight and I am  wondering if that is necessary.  > Hank  >
