Regarding the setup of Inspiration Scrubber units... I ACCEPT the fact that the unit was designed to insulate the Sofnolime from the cold water by use of an air cavity. I am new to rebreathers and am puzzled about the resulting impacts?
1. Why is the pack mounted on springs?
2. Don't they go BANG as a diver lands in the water, and cause the O ring to break it's seal?
3. The Spacer Collar above the O ring seats in a bevelled channel, so will it not be displaced, and leak, even momentarily? Gas would rush PAST the scrubber, fuelled by the gas wavefront created by the piston-like cannister throw on that spring!
4. Why are there not additional seals around the belly or middle portion of the scrubber walls, so an O ring there would always make contact with both surfaces, regardless of travel magnitude? These would keep the alignment correct thereby maintaining seal integrity.
5. Maybe there is no need to concern myself, as the CO2 is not kept on one side of the scrubber, but rather ABSORBED by the chemical reactions taking place in the material. But what about gas that bypasses the scrubber past the top O ring/collar seal?
Perhaps someone would be so kind as to share their experience with respect to the inevitable high impact (upon entries) on the scrubber for lets say a typical "giant stride" for example?
6. How does the sprung Sofnolime Cannister not slop around?
7. If water were to collect in the scrubber, then if inverted, would be allowed to wet the wiring, cells etc. So why is there not a watertight seal around the scrubber cannster? This would require ingress via the scrubber material itself, thereby maintaining vital function to continue unhindered.
8. Why is there not a water sensor in teh bottom of the scrubber? It would be powered by it's own battery and simply activate a buzzer when the probes detect water level threshold.
