There are some anomalies though, which are worthy of discussion. The Optima result is a particularly interesting one. The Optima is designed for 1.35l/min of CO2 for 3 hours. If RMV is maintained at an unrealistic level, it will break through MUCH earlier. The CE level of 1.6l/min of CO2 is unrealistic, and it causes off effects here.

It was explained to me - that if the CO2 rate was lowered than the other scrubbers would do proportionally better too. So again the cartridge would be last? Is this wrong (I understand the basic theory behind it all but dont profess to be an epxert or have played with test equipment)?

Or does the amount of CO2 really make a difference with some designs more than others? I believe the Optima was designed with a target of 1.35l of CO2 rather than the 1.6 of CE and that makes the difference as no one is going to product 1.6l of CO2 for hours...

Now I just need to find out how my Meg Radial scrubber does :-) as the WOB is excellent!
