Started My On Board Air today.

I've been planning on making myself an OBA system for a long time on my commander. I've been hoarding a bunch of parts for a few years.

Today i started with my tank. I used an old CO2 fire extinguisher bottle for the tank. The tank is aluminum and holds 1.5-2.0 gallons of air. I'm not sure what pressure it can take, i suspect around 2000 psi.

anyway here are some pictures. i did a write up on my website if you want to do your own. i need to find a few more parts to finish it all up, but that shouldn't cost anything.













this is the other part of the system

I think it is a dryer for removing water from the system with a drain at the bottom.

Looks interesting. I dont know much about OBA. Will you be able to fill all four tires with that after airing down?

yes. i will be able to fill my tires a little faster with a tank and possibly run air tools.

The Blue canister is a charcoal water and air seperator (air dryer). It just dries the air so your tank won't rust out. since my tank is aluminum it would not rust out anyway, but its always a good idea to have one on board.

i'm only adding about 15 lbs to the jeep with this whole system.

Might have been easier to buy a PowerPlant winch. I can run air tools and inflate each tire in about 2 minutes each.

But your PowerPlant cost approx. $1000 and Im sure he paid only a few dollars for his current OBA setup.

Stored preasure CO2 fire extinguisher are desinged with MANY different working preasure ratings .. that paticular Kidde unit is a fine choice for an air tank ... and it is designed to operate at 850 PSI.
