I am building a scrubber for the VAST sub. The housing I acquired was a carbon filter used in the grow industry. With an interior screen core for the air to flow thru to the sodasorb core to the outside screen. The volume of this space holds 3.6 lbs of carbon. Not sure if the weight per volume of the sodasorb is exactly the same, but if it is that chamber would produce about 14.4 hours of absorption. I'm am thinking that I am going to cut the unit in half. My thinking is that for a typical day of diving, 14 hrs seem a bit excessive and I would be wasting a lot of sorb. With pre packaged, vacuumed bags I can carry what would be required to meet ABS guidelines. One of my concerns though is that with the compactness of the VAST sub with a reduced volume of sorb, would the heat generated be greater than with more sorb, thereby also increasing the humidity buildup.<DIV dir="auto">I am hoping to get some experience feedback from other small owners, and what they have used volume wise of the sorb for a typical day of diving. The co2 unit I am using measures humidity as well as co2 ppm. </DIV><DIV dir="auto">Attached are pictures of the unit ready to have the fan attached.</DIV><DIV dir="auto">Best Regards,</DIV><DIV dir="auto">David Colombo<BR><DIV dir="auto"><BR></DIV></DIV></DIV>
