Help Needed With Co2

[george4593]

could do with a bit of help,
i have read about DIY fire extinguisher co2 on this forum and its made me want to change my setup as i am not currently using CO2
 
 
if using a 2kg co2 fire extinguisher then how long would it take to empty on a 150L well panted tank on average???
 
I'm trying to work out prices etc 
 
thanks

Mine ran for about 5 months @ 2.5 bps on for 7 hours a day to get 20+ mg/l displayed on my JBL "drop checker"
Edit (I did use an old out of date extinguisher that I obtained for free so perhaps more run time will be had from a new extinguisher)
