CO2 when running out

[Bradders]

Hi All,

I noticed that the cylinder pressure gauge (1.5Hg cylinder) is going down slowly. It was around 800, now 650 PSI.

Do you wait until near zero to replace, or is there a best practice to replace at X PSI, etc?

Thanks,
Brad

Depends on where you have a duel stage regulator or single stage. There is an potential end of cylinder dump of CO2 issue. I have never had it happen.
With a single stage regulator you can have an end of cylinder dump of CO2 when the cylinder gets low in pressure.
With a duel stage regulator this end of cylinder dump doesn't happen.
I ran mine until the working pressure started to drop

Do you mean it doesn't happen?

I have a dual-stage regulator. So, is it best to let it get to Equalibul with the working pressure?

Yes, doesn't happen with dual-stage. Mines is at around 500PSI so just hitting into the red on the gauge, I plan to just use it until I can't anymore (I'm on dual-stage).
