<div dir="ltr"><div>Alex, thats what I thought. The filter did come with a fine mesh bag, and the outside fabric cover I assumed that would be small enough. I need to find some ss snap clamps to pull the cover down. The fiter did come with foam donut at both top and bottom. I was going to replace that with a litter denser foam to help in the compression.</div><div><br> </div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>Best Regards,<br>David Colombo<br><img src="http://static.squarespace.com/static/533310a9e4b0fba62008a464/t/5339c1f2e4b041bac4e25d1b/1396294132055/?format=500w" width="200" height="110"><br>804 College Ave<br>Santa Rosa, CA. 95404<br>(707) 536-1424<br><a href="http://www.SeaQuestor.com" target="_blank">www.SeaQuestor.com</a><br><br></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Dec 14, 2020 at 6:39 AM Alec Smyth via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Dave,<br><div><br></div><div>From the photos, I think you've picked up the exact same carbon scrubber I had in Snoopy. The holes are a bit big for Sofnolime, but you can easily add a second layer of much finer mesh stitched to the inside of the existing cylinders with fine wire. Use a donut of foam on top of the Sofnolime to squash it down, so there isn't a path of low resistance for the air to flow over rather than through the Sofnolime as it settles. Also, be sure to use a radial blower, not an axial one. As for the volume, it was perfect for Snoopy but I was diving with two people, so if you cut it in half I think you'll be about right. I don't anticipate you'll get any significant heating. The absorbent will get soggy and can drip, so mount it with the blower on top to keep that dry.</div><div><br></div><div>Best,</div><div>Alec </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Dec 13, 2020 at 10:14 PM David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hi Guys, I was following Jon's thread and thought how appropriate. 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>
