Shebeen Posted February 6, 2015 Share Not sure. Think it's 20bar. It seats any wheel on any rim in split seconds. You must just carefully regulate the speed of the CO2 when you open the valve. And after the tire is inflated, I just deflate and inflate a couple of times with a normal pump just to let all the CO2 gas outooooh, so you're using a prefilled cannister. not filling it up with your floorpump. this is the same as using a sodastream bottle (which is more expensive than paintball cannisters, there's a hack for that too) Wil6 1 Link to comment Share on other sites More sharing options...

The same as they use with paintball guns. Costs R40 to refill the cannister. But think it will last me a while. Link to comment Share on other sites More sharing options...

Edit: Doing some research reveals that this may not be entirely safe either (filling a CO2 tank with HPA) Edited February 6, 2015 by Bobbo_SA Link to comment Share on other sites More sharing options...
Brian Fantana Posted February 6, 2015 Share As shown earlier in this thread, this strap method has served me well even with difficult tyre rim combinations (this method can be used on car/bakkie/truck/tractor tyres as well, provided that you use stronger shackles and belts and remove tension as soon as bead has set, before inflating further): JXV, nicds, Wil6 and 1 other 4 Link to comment Share on other sites More sharing options...

TK-Sp3cialiSt Posted February 6, 2015 Share A co2 canister can only be filled with co2...you would need a dedicated air bottle to fill with air I used to play paintball and trust me you do not want to mess with the bottles in the wrong way Wil6 1 Link to comment Share on other sites More sharing options...

Just strange that my local arena gave me the choice when i had my bottle filled the last time. Link to comment Share on other sites More sharing options...
Mecnic Posted February 8, 2015 Share The main issue with Pressure vessels of any kind is as follows: Under law steel or aluminium canister is they must be hydro tested every 4 years to beyond working pressure, if they explode they fail, I have seen the result of an alloy scuba tank shooting off, it took the roof off the compressor room but that's besides the point. CO2 running at 20 Bar if the cylinder cracks it expands to 20x volume and here is where the danger lays, as it adds 20x the volume to a room already filled with air, same applies to a pressurized coke bottle. It's a good idea but DANGEROUS, expanding air can cause hearing damage etc even if all the shrapnel misses you, a aluminium pressure vessel should also be handled with care as it is brittle and can ruin the structure and lead to eventual failure if mis handled droppped or generally abused. Anything with pressure is dangerous, a standard compressor runs at 8 Bar and the big issue with pressurised air is water vapour and corrosion, my compressor at home needs draining and cleaning regularly from the water in it, same will happen to an alloy paint ball container if filled with air. I was on the road with the UNOGWAJA and used a scuba tank, filled with dried air and used a standard SCUBA regulator to drop 200 bar down to 8 you can set it up to 10 or 12 if you really want, a little expensive to set up but that is ultimately the safest option. It lasted 2 weeks on the road and even refilled a few car tyres. they come in smaller sizes and some can even go up to 300Bar that amount of air will last a while, but same testing procedure applies. (2nd hand scuba equipment after a bit of a search can be found cheap enough.) Cost v Safety, Good Idea YES, safe No (Warnings and all appreciated, I wouldn't do it), Maybe immerse the bottle in water and wrap it in a tube to absorb any explosion (Common use in the SCUBA industry) Link to comment Share on other sites More sharing options...

Cois Posted October 1, 2017 Share So after a lot of going this way and that I made a fire extinguisher DIY tyre inflator. Had an old Halon chubb fire extinguisher to use.Added a presta valve to the top (if I do it again I would use the safety port as the fill port as well.The hose I got from a cycle shop, and the compressor fitting from builders.Used it this afternoon to seat the tyres on the SO’s bike. Will try to post a photo. Cant resize photo’s on my phone ???? Link to comment Share on other sites More sharing options...

Skylark Posted October 15, 2017 Share Which port on a extinguisher would you use to full it up with compressed air? Link to comment Share on other sites More sharing options...
Cois Posted October 15, 2017 Share Which port on a extinguisher would you use to full it up with compressed air?I installed an unneeded presta on the body, but that was before I knew the port on the side of the head could be used.Think it is known as the emergency vent?

Cois Posted October 16, 2017 Share My dad made this one. You can see a little better on this one where the ports are I can get mine up to 9 BAR and it is still a tad bit under the safe green area Sent from my iPhone using Tapatalk Pro johannrissik, IH8MUD and Skylark 3 Link to comment Share on other sites More sharing options...

Just a bit bigger bottle. Will try to remember to take a picture to post. Wish I could get it up to pressure of the rated 15-bar. But usually only manage about 8-9 bar.
