When I travel to my dive site, I will turn on the scrubber while the sub is hot inside and it can get warmed up before I dive. I put a PWM controller on the fan but it performs best at full speed.</div><div id="yui_3_16_0_ym19_1_1487183234485_4559">The new Radial scrubber alone keeps up just fine (1700 PPM ) with the sensor at the front of the sub and the circulation fan running about 1\4 throttle.</div><div id="yui_3_16_0_ym19_1_1487183234485_4559">I will likely need both scrubbers going with a passenger.</div><div id="yui_3_16_0_ym19_1_1487183234485_4559">Hank</div></div><p style="margin-top: 2.5em; margin-bottom: 1em; border-bottom: 1px solid #000"></p><pre class="k9mail"><hr><br>Personal_Submersibles mailing list<br><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br></pre></blockquote></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></body></html>
