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
