Title: 20lb PowerTank Setup
Post by: sn4cktime on October 16, 2008, 04:42:16 AM
UPDATE:
Used the tank today.  Aired my 35x12.5 tires down to 15 psi for the day.  At the end of the day hooked up my four-way air hose (which has a fubared gauge already  >:( - I'll have to change it out) and filled all four tires at the same time in about 30-ish seconds - my math was pretty close.   Longest part was cleaning the valve caps off enough to take em off and cracking open the tank.  Can definitely recommend it.

----

I figured I needed some sort of way to fill my new 35's when I ordered them.  I remembered watching guys fill-up with compressors, it works, but isn't all too speedy (helps with a tank or two for sure, and I thank those that have repeatedly filled my tires) so I figured I'd give a CO2 setup a go.  Got a 20lb tank for cheap (already hydro tested in '07) and just got my PowerTank regulator from Bill tonight.

It can crank out over 300psi at a smoking 45cfm.  Supposedly I should be able to fill one of my 35x12.5's from 15 to 30 psi in about 30-ish seconds.  I've got a 4-way air system coming in this or next week so I should be able to clip it all on, crank it on and give it a minute or two and it should be finished and equalized.

Pretty cheap to fill a dead tank - about $30.  Should put out around 32-40 fills.  Can turn it up to seat a tire bead, or turn it down to run air tools.  Can even turn it WAY down to be lazy and fill up air mattresses and such.

I looked at the posted pictures and the handle is all new-shiny and looks like plastic, it's aluminum.

Was quite a lot for the 300psi@45cfm.  If I can remember I think it was 325.  The 200psi@35cfm would be cheaper.  There's also a non-adjustable version that I think puts out 150psi@30cfm.  No idea on pricing though.

Maybe I'd finally get a good sleep for once!   :D But point taken.  I wonder if that'd be enough CO2 to actually asphyxiate.  It's not as effective as CO (carbon-monoxide)...  Maybe I'll just save that effort for filling inner-tubes/rafts.

Britannia Esso has great air, filled my empty tire real fast. Its not like the slow gas station air that takes forever to fill a tire. I think they use the shops ac and string the hose outside. Check it out, its beside Sunterra on Elbow.
