Hi all,
I've been back and forth about whether I want to go the pressurised CO² route or not. I think the lower pressures and volumes of CO² made by the citric acid approach is safer, which appeals to me.
Looking at the stainless steel reactors they look like a safer option than the carbonated drinks bottle options as I've seen a few reviews where the plastic bottles have split overtime.
The cost of the stainless steel reactors is quite high and I was wondering if there was a cheap and simple DIY option. I use a couple of these pump sprayer bottles for various things and as they're fine with corrosive liquids and can handle 43psi before the safety valve is triggered I was wondering if I could use one of these in the same way as the stainless steel bottles. I.e. fill it with the correct amount of citric acid, bicarb and water then hook it up to a solenoid, needle valve and diffuser/reactor. A quick search on here suggests the pressure required for a diffuser is about 30psi, so I think the bottle rated to 43psi should be ok. My question would be what happens when the solenoid is closed, would CO² just vent through the pressure valve. @GHNelson I saw in your journal you've used the stainless steel type generators. Do you know what the max pressure in the bottle is when the solenoid is closed? I can't seem to find this info online.
