<div dir="ltr"><div><div><div>Hi guys,<br></div>I can't see any particular issues with adding activated carbon to your scrubber (and it's used as the final filtration in most SCUBA compressor filters) so long as you avoid dust.
One thing to be mindful of is that it's a fuel and shouldn't see high oxygen concentrations. If you wanted to be really fancy, you could also add some "hopcalite"/"monoxycon", which is a granular catalyst to convert carbon monoxide into carbon dioxide (also used in SCUBA compressor filtration).<br><br></div><div>Alan, I have Lawrence Factor (high grade breathing-air) activated carbon and hopcalite in Australia already if you need some, but I think you would find them in NZ.<br></div><div><br></div>Cheers,<br></div>Steve Fordyce<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Feb 3, 2018 at 10:41 AM, Alan via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto"><div>Sorry forgot link, (getting old)</div><div id="m_7382519201475722288AppleMailSignature"><a href="https://www.amronintl.com/comex-lung-powered-carbon-dioxide-co2-scrubber.html" target="_blank">https://www.amronintl.com/<wbr>comex-lung-powered-carbon-<wbr>dioxide-co2-scrubber.html</a></div><span class=""><div id="m_7382519201475722288AppleMailSignature">Alan</div><div id="m_7382519201475722288AppleMailSignature"><br><br>Sent from my iPad</div></span><div><div class="h5"><div><br>On 3/02/2018, at 11:47 AM, Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a>> wrote:<br><br></div><blockquote type="cite"><div><div>Just doing a quick Google I came across this lung powered CO2 </div><div id="m_7382519201475722288AppleMailSignature">scrubber that has a carbon filter in it as well.
