Hi Charley,
[quote=charley;166056]I haven't seen any pictures showing the filter that supports the media at the bottom of the cannister. It is the same filter as the one on top??? Is it strong enough to support the weight of the media???
The bottom filter is a mirrored version of the top filter. Supportng the weight of the sorb, (2,8 kg Draeger sorb or 3,4 kg Sofnolime), is not a problem. There have been two instances where the bottom screen has broken due to misaligning the Co2 pipe and then using body weight to push the head back on. Body weight is not supported by this screen so then they break. There is an easy way to align everything so this does not happend.
Any packing mechanism?
No. You have to pack the sorb properly. An axial design is more forgiving than a radial, but the job needs to be done properly. So far no one have had any problems with channeling as far I know. If you are familiar with the Classic Kiss, our scrubber works the same way, but you can take the bottom plug off without loosing the sorb. On a CK you can't.
Are there any insertions or restrictions that push to flow of air towards the cell or can it just bypass them???
I assume you mean "bypass" to the extent the cell does not register? No this is not a problem. In fact the cell responds so fast that we have problems with the respond time being too slow with most third party dive computers or other monitors. The reason we like fast update is in order to take advantage of our Instant Cell Validation that lets you validate your cell readings in half a breath of diluant at any depth. That is if the monitor is fast enough to up date...
How do you access and where is the battery compartment?
The 9V battery is inside the scrubber head in its own 1 ATA compartment. You replace the battery by removing the battery lid. The reason for this is that I wanted to make the display case as small as possible. If the battery would sit in the display case I would either have to use small batteries for frequent replacement, or accept a large display. Didn't like either of them!
Andy claims that you can fit 2x 80 cu/f tanks on the scrubber but, isn't the ADV's fitting in the way???
When the angles and webbing slots were designed for the X-Wing mounting plate I worked with both 19 cu. ft's and 80 cu.ft's to make sure they both worked without interference by the ADV connection. I also adjusted the angles so that even with AL 80's the top profile is not higher than the scrubber. Using 80's is extreeme overkill, but might come in handy diving with a non-Rebreather friendly resort that likely only has 80's. They will also only have right hand K valves, so you can just carry one back to front. Wont look pritty but you will go diving. Just make sure the tanks are clean, (clean them your self!).
Is the ADV an S600 just like the BOV? S600 aren't really the big winners in sub 40F temps like those we have here in Canada... Having an S600 on a BOV doesn't seem like a big problem but on the ADV I can see it becoming a real PITA...
You are right. That is why the mechanics of the ADV is from a low performance reg that can be set to give you all the resistance in the world. The new ADV membrane is very tough and you can do POS/NEG tests as long as you want.
Does Andy still makes regular heads w/o the ADV but equiped with a push buttom fonction like seen on this prototype's picture???
No. The disadvantage with increased production volume is that customization is suffering. Still it would be possible, but you would be paying more to get less feats. Instead why not just put a flow stop on it and install a manual feed in the counterlung? Much cheaper! Plus if you want to use the Instant Cell Validation, just open the flow stop and use it.
Does he have any plans to produce a cover for the diaphragm???
The ADV diaphargm cover is tough like a hockey puck. If you mean a soft rubber cover, then no. The ADV needs to be well protected as it sits on the top of the unit. It needs to take the abuse scraping it against the cave ceiling.
This is also why we changed the ADV membrane. The new menbrane would survive getting poked through the purge hole by sharp wreckage as it has a SS reinforcement plate on the top.
If you worry about beign able to purge through the hole with drysuit gloves you can stop worrying. You dont need to purge it. You just lay on your back to auto flush the loop.
