extinguisher bottle as an air tank... how do i set it up?

[MUSS]

pretty sure endless air is over 350 just for the unit then you got brackets and fittings etc.
I hate aircon anyway no matter how hot it is so it was a logical swap for me and so far in about 18months or more have had no probs at all

us CRUISER blokes think alike

[Hoonz]

ok heres the big question ...

how much for the complete endless air set up ... not installed

[turps]

Cost for the lot from endless air (kirelle engineering - yes it's splet wrong I know).
compressor - $350
Brakets and other crap I think was over $300 also.

Dads got the broucher some where will see If I can find it

[Wooders]

Sorry to bring this back upto top - but I'm curious......
I wasted a shyte load of time the other weekend goign to every car & truck wrecker I could find....the CHEAPEST tank I could find (inreasonable condition) was $300.....Which is a joke becuase I know I can buy em new from places like snake racing for less......
But I wanna know WTF these $20-$50 tanks are

Bugger it I'm goign the Fire Ext way too

[phippsy]

Wooders, I didn't look to see where you are, but a truck spares shop in Rocklea Brisbane had large air tanks the other week on special for about $50, I think they were about 50 litre volume or something like that.

[robbie]

50ltr tanks, how big would that be physically?

[bogged]

But I wanna know WTF these $20-$50 tanks are

Rod grabbed one from some truck wrecker out Epping way for $15 when I was there, and WOOP has 4 in his truck, ask him which place, actually hes mailing me the details, we are doing to do mine soon as his donk is finished, I'm going to run 2 tanks probably.

[r0ck_m0nkey]

As far as working pressure for a Fire Extinguisher goes, it should be printed on it's label. I will get a few different working pressures for various bottle sizes and types tomorrow at work. (i work for a fire protection company).


Just going off the 4.5kg Dry Chem (red w/ white band) i have in my house
has a working pressure of around 1400kPa, but tested to a pressure of 2500kPa.

Wanless Truck Wrecking - Boundary St Rocklea
get a tank off a cab over kenworth - air reserve tank
if you pay more than $50 you are getting done.

why not just buy one of the cheap air compressors, they are under 100bucks and i saw one at autobarn with a nice tank that would fit in engine bay. Through away the motor and air pump keep the tank pressure release all the fittings drains pressure guages etc etc. What aree you guys thinking these things are dirt cheap now

Is that the one with the air horns? If so wouldnt hold enough air to pump up 1 tire.

[berazafi]

i wasnt talking about the actual compressor, use your air con i was just talking about a small tank fittings etc etc

[bigbluemav]

I got my tank (relatively small @ 10 litres) from Kelly's Wrecking at Beams Rd. Carseldine for $30 with the mounting bracket.

The bloke there said all the tanks were about $30. They're all still on the trucks in the yard, you just choose one and they'll take it off. Still thinking about getting a bigger tank, or another to add.

All the bits I got from the compressor place and Enzed fitted perfectly. Great system, well worth the effort. I can air up my 35's 20-35psi in less time than it takes a "good" 12V compressor to do one!!!!

[Wooders]

Thanks lads

I really need to get my OBA sorted as my new suspension arrives soon & it will require a good supply & 12V woun't cut it

50ltr tanks, how big would that be physically?

http://www.bigballsoffroad.com/prod2429.htm

Air Tank 4.625 litre


http://www.bigballsoffroad.com/category43_1.htm

Comes with 25 litre full galvanized tank, pressure switch , preasure gauge, relief valve, circuit breaker, pressure relief valve , quick connect , drain valve etc


50 ltr??

I was talkin about the airhorn kit with an air tank they have. They have it at local Autobarn small red tank, but you have to use servo to pump up the air tank.

I doubt that is 4.625 ltr volume..

a sub box that is like 45-50ltr is half the size of a commodore boot ..

if you want a good strong compressor you will have to check out this linkhttp://www.toyotasurf.asn.au/forum/ ... php?t=1466 it is worth your while to check it out

Take a look at the picture. The inlet in the end is prob only 1/4".

That's the prob with the internet, without perspective in the picture it is never as small/big as you think.

[TwistedMQ]

What is the eaisiest way to mount the fittings to the bottle? 1: try and find a mainfold that will screw in to the top off the bottle where the hose of the gauge is or 2: drill and tap a hole in it and go from there, any help much appreciated.

thanks John

[customhilux]

the co2 bottle is a good idea,

just check the max working pressure,

what rock monkey said before, his had 1400kpa which is 203psi

that is plenty, most of the 12v compressors wont go much over 120psi i think.

your goin to have to run a check v/v at the opening of the bottle, so u wont have bottle pressure running back up the compressor line.

u also need a pressure switch to turn the compressor off at max pressure and cut back in when it drops below say 90psi.

you'll also have to run an emergency relief v/v incase ya pressure switch doesn't cut out.

pressure gauge won't hurt.



i'd hate to tell ya to u won't be able to measure the wall thickness of the bottle because of the gland on it, it's goin to be a diff size to the barrel.

12mm would be the thickness of the gland, i'm goin with ruff it's prolly a 2mm wall thickness,

but look out compressed air is dangerous, i would rather work with hydraulics most of the time than air, it's to unpredictable.

hope that helps.

[berazafi]

i am currently doing one, i will set up a full how to once i am finished, best info though is buy a GMC compressor with 24L tank from bunnings.. 98 dollars, rip of the compressor and motor and you will have just about all you need, saftey valves, inlet blow off, drain tank, pressure switch adjustable etc etc... any way keep a look I will be doing a full how to soon in the nissan section, i will post a link in general to

[customhilux]

yeah thats prolly the safest way to do it.



but it still is cheap parts,


has anyone ever had their tank over pressurise, and blow an end cap off

[berazafi]

the parts may be cheap but they are all certified the tanks must be individualy tested to be sold (i belive), the pressure release valves must be rated (tuv or similar) the pressure switch also but at 240V. buy any one (by any manufacure), just make sure it is approved. eg a n/q/v or s followed by 5 numbers

[MUSS]

time to revive this thred! i have picked up a BOSS 3/4 hp air compressor (same ones hobzee sells on his ebay store) for a couple of hundred bucks with a 20ltr air tank, pressure switch, relief valve, non-return valve , a manifold for the lockers and some descent hose and connections should do tyres, airhorn, air tools, and rear air suspension with ease from what i have read (here is the info from hobzee's ebay add)

12v 3/4 Hp Air Compressor by BOSS Suspension.

This unit is of exceptional quality with steel components, not plastic. It's specs are :

Massive -- 35cm long, 25 cm tall, 18cm wide. This is without doubt the biggest and most impressive compressor out there..

3/4 Horse Power

3.5 cfm @ free flow

Max pressure 200 psi

Working Pressure 0-150 psi

100% duty cylcle - just keeps going. All others heat up and stop.

Draws max 25 amp on start up under pressure.

12 month warranty.

Ideally this unit would be fitted to a vehicle to pump up tyres, run diff locks or operate air tools. Although perfectly capable of pumping up tyres without an air tank, best pumping and air tool results are achieved when using a tank with pressure switch. We also sell a range of tanks, pressure switches and accessories.

Putting this in perspective this unit is in a legaue of its own. It is so much bigger and faster than anything else it is unfair to the competition to make comparisons .... but I did! Check this out..

(filling a 33x12.5R15 Cooper ST from 20psi to 35psi)



ARB (Large); 1 TYRE- 3 min 20 sec, 4 TYRES-13 min 20 sec

Bushranger; 1 TYRE- 2 min 15 sec, 4 TYRES- 9 min

Boss 3/4 w/o tank; 1 TYRE- 50 sec, 4 TYRES- 3 min 20 sec

BOSS IMPRESSOR Kit; 1 TYRE- 23 sec, 4 TYRES- 1 min 32 sec
(Boss 3/4 with tank) GAME OVER

[nicbeer]

A mate of mine made a tank out of steel, going to do one for mine also. runs cut off at 150psi i think for airtools and more air flow.

5-6mm steel wall square section (same stuff they make the signs at the shopping centres and same steel plate or thinker on the end plate.

think his is 600mm and about 150mm sq

nice to fit inside chassis and seems good so far after 3 or so years always charged up. always drained every month or so if needed.

i made my tank out of a fire extinguisher.... plugged the neck, drilled two 1/2" holes and welded 2 3/8" BSP sockets on with the mig welder..... runs up to 100psi with no dramas. I have a 3 litre tank in the ass end for the front locker, and the one under the bonnet runs the air horn. Because it's run through a regulator, it doesn't feed back into the other tank. I use a 150lpm dual head compressor to feed them both and it takes less than 2 minutes to charge the system initially, and less than 20 seconds to bring it back from 75psi to 100psi. A dry-chem extinguisher would be fine for a tank... just make sure it's welded properly, or, just use the thread on the neck of it and screw a "T" piece into it for supply and drain.

the one in the back......


And the tank under the bonnet

Hi Muss
Where did you get a BOSS compressor for a couple hundred bucks?
Sounds to good to be true.
Cheers
