Do I need a bigger scrubber?

[Digger]

Well, now I've been thinking about things and planning mods to the P1SS, Duncan's suggested a bigger scrubber for a mixed gas unit etc.

Now, my question is this. I work on the basis that the P1SS will do an hour to hour and a half reasonably easily provided it doesn't flood. This is getting fixed, but most of my dives are about an hour at the moment, so surely the scrubber is perfectly sized?

How much over planned dive time should I have the scrubber? Do I need a bigger scrubber really?

I can see days at Stoney or getting two dives out of the unit in a day being a problem, but then I can just pack another scrubber, as they're cheap enough to make another one.

This is obviously not at the moment, I'm just trying to plan for the future before setting myself up with this scrubber and having to change things later. There's a whole loit of valves and monitors got to go on it before that's going to happen.

Thanks.

Next question. If I do need a bigger scrubber, anyone replacing theirs, or know a good design for another one?

Why don't you sod off Jack. Every time i see "Scrubber" i come here and find it's you talking about RB's.


Anyway. Big ones are better because there's a lot more to keep you warm in bed during the winter, imagine a giant hot water bottle. Plus they don't use much bath water because of the 'Eureka' effect.

Digger is talking about 'packing out' a big scrubber - I'm not confident he would manage it!!!

Christ. 2 responses and it's you pair. Predictable boys. Very very predictable. But quite funny mind!!! (that's all that's saved you from the red blobs)

And Angus, I'm fairly confident. That said, most of them you've got to first.

I Wish!!!

Hows about one of these?

[Doug Parker]

I'm just bumping this because i feel guilty. Diggs asks a perfectly reasonable question about scrubbers and because a couple of pisstakers get in first, it frightens you RB boys off.

Digger,
what sort of time are you looking at on the scrubber? And are you looking at DIY or purchasing one?
For purchasing one I'm looking at either a 3 hour scrubber from Tubby (http://www.vk4tub.org/tubby/Abyss_Re...arts/index.htm), which works out at a tad over £300 after you've had to pay duty etc.
Or there is the posibility of a 6 hour scrubber from another source at approx. £400, (can't currently discuss it on the forum, I'll send you a PM).

Regards
Simon A

and thinking about John's mate who can weld plastic, you could get the frenzy plastic welded off into 3 sections, inhale and exhale counterlungs and buoyancy bag (run like a BC)

right yes you want a bigger scrubber if you going to use the thing for more than pure O2
read what happens when Gordon Henderson is abducted by aliens to explain how

would make me think that you'd want a bigger scrubber 2.5 kg seems good (3hrs ish)

i'm not changing my scrubber i'm afraid you'll have to buy (as if) bui;d your own - good for a laugh just bolt a dustbin on your back
