Air Compressors

Well I wasn't sure what to stick this under so we will try here.  What does everyone use to air up after wheeln' Compressors?  Who makes the best?  Powertanks?  How long do they last, if only used to fill tires?  Need to get something and would rather buy the right thing first. Thanks  

i use a little compressor that plugs into my power outlet. it's small and don't take up much room. i see alot of guys use nitro tanks that will fill your tires quick but you have to to go get them filled all the time. not shure how much it would cost, you would have to check your local shop that fills tanks like that. airgas is one of my local shops.

I can get a 20lb tank for about 60 bucks and refill is about 45 bucks.  However they can't tell me how many air ups i will get  

depends on tire size and now much psi they put in your tank.

It's not a nitrogen tank that you want. The tanks that you see people using are CO2 tanks. There is more to them than just the tank.

PowerTank, The Source, and Ultimate Air are a few of the more popular CO2 systems. They all cost between $300 and $450 depending on the size and how complete the system is.

You can get an aluminum cylinder for around $80 and a fixed pressure regulator w/out gauges for about $50. That would be the bare minimum that you would need. Then you'd need a hose, fittings and some way to mount it to protect your head, the valve and regulator from damage.

CO2 fills only cost $10-$15. You have to find a place that will fill YOUR bottle. A lot of welding shops don't fill them, they exchange them. And you don't want someone's beat up steel tank in exchange for your nice aluminum one.

Gauges are useless. Don't waste the money on them. The tank stays at its full pressure until it's just about empty. The only way you know how much is in your tank is to weigh it. It is very important to know how much your empty tank weighs (Tare Weight). Then when you fill it you can weigh the filled tank and subtract the tare weight. If the tank is over-filled, which is very common, you have to let out the extra. This is critical becuase when the tank warms up it will build too much pressure and then it will pop the blow-off. You'll then need a new one and all your CO2 will be gone.

 

Well what I found was a 20lb tank at the local welding supply place.  They got a bunch of old 20 lb tanks and recert them and are selling them.  Well probably exchanging them.  They would be filled with co2.  Thanks your chart helps alot.  Just trying to figure out what would be the cheapest for "air" in the long run.  Cause I got nothing now so starting with a clean slate.  I'm kind of leaning towards a portable air compressor.  Mainly cause I will only use it 4 months out of the year and would like to keep compressor in the shop when not needed, not bolted to the jeep.  Are the viar compressors any good? cause thats what i've been looking at.  Thanks
