Gamma has 3 axial scrubbers, one is Gamma'a original scrubber from 1971 with a smaller quiet fan. The next one is a home made scrubber made the same as Gamma's original, the third is a re-breather scrubber with a computer fan.</div><div id="yiv0122833245yui_3_16_0_ym19_1_1527302376374_43273">Interestingly after reading through some information Cliff sent me, I learned that the flow rate is critical. The only way I can change that is to fill the scrubber canister more or less. I started with 3\4 full canisters and a full re-breather canister and had a CO2 level of 950 PPM. With all three canisters full I had a CO2 level of 1133 PPM. So clearly the flow rate makes a big difference. </div><div>Now I understand why Gamma's original scrubber had such a big fan, in order for the canister to be full, the fan needs to be quite powerful.</div><div>I also have a true appreciation of how well the altimeter indicates how well the O2 level and CO2 level are monitored.</div><div>If the Altimeter was off zero even the tiniest bit, it correlated with the instruments perfectly. </div><div>Hank</div></div></div></div>_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" target="_blank" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a rel="nofollow" shape="rect" id="yiv0122833245yui_3_16_0_ym19_1_1527302376374_43274" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"><br clear="none"><br clear="none"></div></div> </div> </div> </div></div></div></div><div class="yqt3071688722" id="yqt52011">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div></div>
