So I got a cootwo and it consistently tests the air at .3-.4 ppm CO.
I got the nitrox stick set up and used a 1" flexible pvc hose to plumb it to the Rix. The hose smells like pvc and I've searched high and low for a better hose with no smell but the best I found was 26$ a foot silbraid silicon tubing. I pumped some air through it and it tested and smelled fine. I finally got the bank tanks back form the shot blaster and hooked up the nitrox stick. The good news is the blending is super stable and once adjusted it will run for hours with only minor tweaks and I was getting 31.9% with a CO reading of .3 ppm.
The bad news is the pvc hose is imparting a bad plastic taste to the air. The filter was taking it out but after a while it must be overwhelmed. The odor coming off the coalescers is plastic. The air coming out of the scuba regulator is like rubber. There is no reason to have trace analytics test it. I'm not going to breathe it. I taste tested the air when I started pumping it and then banked 1400cf of 32% which is what I got out of a T of O2. At the end I filled a scuba tank and it tasted like rubber. The banked air wasn't as bad so I figure the filter gave up a few hours into the pumping. I wasn't too keen on counting on the filter to clean it up in the first place so this result was not surprising.
I dumped the banks out the window and resumed my search for a hose. I finally settled on ordering a flexible intake hose from nuvair that they say has no odor or taste. I'll replace the filter when it gets here and start all over. 2 steps forward, 1 back.
