I bought the CO2 scrubber as a kit from Ai Research.  Someone else has already done a good build log of this kit so there is little point in me repeating it.  It was straight forward to assemble.

Just a couple of things worth noting.  I added 2 “D” handles to the top to assist in opening the lid.  I just happened to have some spare.  Added a 30mm (I think) pipe connector to fit an outlet hose to.  Added a 24v green led light so I can see when the scrubber is powered on.

I also insulated the connection socket as it was wired with negative earth.  I drilled out the hole bigger and fitted a Delrin plug.  I agree there would have to be some fault for it to cause a problem, but it could have opened up a connection to the negative battery terminal through the hull if something live came adrift and contacted the hull.  I am trying to be careful not to get any shorts.

I don’t like the silly angle it’s mounted at, but it’s the best place for it to fit at the moment.  It won’t quite stand up straight with the scuba tanks where I have put them.  Possibly an adjustment needed, some other time.
