If you are running compressed air...do you even need a regulator or does the tank pretty much do the job for you?

Okay heres a few lessons...
Co2 tank- When c02 is released out of the tank, you really do not know what pressure you are going to get... that is why you can sever velocity spikes with a c02 tank if you arent running a regulator setup.
Now with compressed air tanks, the regulator on the tank regulates the air coming out of the tank. On hp tanks, it is usually preset to around 850 psi. On Lp i believe its usually 450, not 100% positive though.
But just because those tanks have regs, doesnt mean you should neglect the use of a secondary reg. A vertical reg, will then take that preset pressure out of the tank, and then regulate the air even more as it will travel an even shorter distance to the valve.
So no you do not need a regulator, but probably 99.9% of people who have compressed air tanks, use a secondary reg... for a reason.

Wow i havent talked about this stuff in ages... lots of cobwebs i gotta clean out of my head.

Well sorry to sound retarded, but will my compressed air still work good with a expansion chamber?

In this case ^^^ the expansion chamber is a waste and just acts as a gas thru grip. The expansion chamber allows Co2 to "expand" from a liquid to a gas.

Totally useless for HPA, but won't hurt it either. A reg is still the best bet for both Co2 AND HPA.

I know what you mean Xtra - I have to think pretty hard to remember all this stuff as it's been awhile - especially on Co2...

Haha no worries... it will stick work well with an expansion chamber. In theory, an expansion chamber is suppsoed to hold the c02 and let it expand more, reducing liquid c02 into the gun. Notice i said in theory. Really expansion chambers only act like foregrips. So really having the expansion chamber will serve only as a grip to you now.
1. If you play on going LP (go for efficency not low pressure) you need a regulator just to regulate a lower pressure then 850.
2. I dont reccomend anything besides a hp present tank. You can use them on basically anything.
3. If you do decide to get a compressed air tank, i strongly reccomend a Crossfire (you will see people calling them crossys.)

Cheers.

My local wal-mart does not fill tanks, but they have a tank exchange program, similar to the lp propane exchange. It's 4.88 for 9oz co2 and 7.88 for 20oz co2. I know Abe said the purchase was already made for the compressed air tank - but still thought I would share that sometimes there is a tank exchange program.
