powertank.....

[toy87]

Powertanks are running over 300 dollars , does not seem worth if, however i have found a 9scfm regulator that runs up to 300psi for $50 and a 20lb tank for $100 or less. so all i would have to add is a hose and tools, Any body else made a cheep powertank , is the high flow valve on the PT necessary or will mine work. also what are your opinions on powertank, seem like a easy portable high pressure source, is it all is cracked up to be.....    or

It's done all the time, my friends race team uses a fullsize tank and they even use air-tools with it.

Whats wrong using a welding bottle and throwing on a regulator?  Aerent these over priced powertanks the same thing???  I know that the quick air systems are waaaaaay inflated and have identical counterparts without the flashy name.

seems to me for 100 bucks you could have a york compressor and oba all the time,,no refills no worries all the time..

I like the idea of the power tank,,just seems to be more money then its worth whn oba is a pretty simple set up..

That's what I was refering to when I said fullsize bottle, they just get the bottle put a regulator on that has air fittings on it then attach to it with hoses like you'd do with an air compressor. They do make small bottles about the same size as a Powertank, so if you don't mind that ugly welding tank look you can do it. Just make sure to protect the regulator so that it dosen't get knocked off.

Gotcha, I think I may do that. I paid 100 bucks for the bottle I have for my welder, im sure you can find the type they use for piantball cheaper, ebay etc...

I'm using a co2 tank from a fountain drink machine. It's an aluminum bottle about the same size as a powertank . I have a buddy that owns a convienence store and I got it from him for $40 . I don't have a "high flow" regulator like the powertank (my regulator was free) but it works great , just a little slower. I bought a really nice fire extenguisher mounting bracket from my local fire safety place for about $20, so I only have around $60 in the whole setup.

I had a few of the 20 oz paintball tanks so I used those. I got a hose for around $30 from the paintball shop that is meant to go from the tank to the paintball gun. I took off the end and screwed on an adapter so it would be standard size. No regulator, but I've gotten pretty good at opening it up to just the right amount.

When I was Auto-crossing I used a Nitrogen tank and a regulator I got from my Dad for an oxygen tank. The tank was small like the power tanks and cost $5 per month to rent from the welding shop and around $20 to fill it. It would fill 225x50x14 tires just as fast as an air compressor and I could run air tools. I a full tank would last two seasons of racing. I was filling little tires and would only change about 5 psi per event. Nitrogen is a good clean gas and doesn't freeze. It does not have the same capacity as CO2 and I think it costs a little more. I would think you could rent a tank for CO2 if you wanted to.

I guess there is a general rule if you use a regulator for something other than oxygen you should not use it for oxygen again.

hey guys thanks alot now i feel better about it, I will also be using this set up for a kegerator at my next house, so i will have a dual purpose tank, SWEET.

A buddy and I built exactly what you are thinking of back in '94, using welding CO2 tanks and a regulator.  Tanks worked great for reseating a bead and filling up tires.  I used to get about 16-24 tires out of a 20 lb tank, the number of tires depended on how low psi I was running.  As far as using air tools with the, I found that when the tank was hot(summer day) I got more usable pressure than durring the winter.  The tank pressure in the winter would run about 1100 psi and in the summer as high as 1600.  If yuou have a welding supply shop near you just swap the tanks with them, this way you don't have to ever pay to have the tank recertified(pressure tested), most tanks are good for only 10 yrs.

I got tired of having to get the tank filled($13-17),and it became harder when the local shop closed, so I went to a 12volt set-up.  The Superflow MV50 that Kragen sells for $45 works perfectly for filling tires, if you have A/C, otherwise get a york at a wrecking yard and fab up a mount(or buy a mount online).  I have seen the yorks aslow as $35 at wrecking yards.
