Small Video On Preset vs Adjustable Tanks

[Z-man]

As it seems many of my videos are, this was made on the spur of the moment with the help of Carbon. This is a brief (relatively speaking) video demoing how a preset tank and an adjustable tank differ in performance with the RT valve.

This is Carbon's E-Mag (software 4.0) running in Hybrid mode. We chose hybrid mode as neither of us is very good at walking the stock 2 finger trigger and the hybrid bounce allows you to see how well the tank's reg does at high a ROF.

Note with the preset the number of chuffs (and balls that plop out of the barrel). The Crossfire tank is unable to provide the air pressure needed to sustain the fire and chuffs often.

Now the Max-Flo was not set at 800psi output like the preset. I think it was set around 1000psi . While this invalidates some of the results considering there is more than 1 variable now, it still demonstrates the point, which is this.

You don't get an adjustable tank to leave it at 800psi and for an RT valved Mag, that is precisely what you are looking for. An adjustable tank will give you the ability to tune the marker to respond ideally at the ROF you tend to shoot, or (hehe) boost your ROF if you want something more to make yourself feel more of a man

Oh yeah and pay no attention to the fact that more of the video is actually Carbon's and my discussion on the superb accuracy of the testing but we felt that such results would warm your hearts and you would not mind the extra 10MB of it.

Zak, you never cease to amaze me.




and for bonus points, I got to see that vid before anyone else did ::thumbs up::

May I complain agian that it is quicktime?

Sweat vid... atleast it should be. I still have another 2 hrs of downloading to go

i think i read somewhere that 3k tanks had a slower recharge rate then tanks that used a 4.5,would this make any difference?

[blykins]

Cool video. Rapid fire is so cool.

I think it is the amount of pressure behind the reg that changes the recharge rate. If that is correct, a 4500psi tank would recharge faster, atleast untill it gets below 3k. I could be wrong. Anyway, the maxflow and dynaflow regs recharge faster then any loader can keep up with.

does a low presure tank work with an auotmag is it better than a high presure?

whats different about the low presure and high presure tanks does the low presure work better with some guns or different setups? which work better with a mag?
thanks steven

[LittlePaintballBoy]

High pressure is definately better for a mag, some guns need low pressure (mainly electros, too much air pressure will blow the 'noid) to operate. If you ask me the perfect pressure for a mag would be around 850 PSI, which most preset tanks are at, the only problem with presets is most do not have the recharge rate of adjustable tanks.

Unfortunately, you're incorrect. A 4500psi tank may have the same output as a 3000psi tank. The difference is in how much pressure they can hold, not how much they can put out.

low presure

so will a lowpresure tank even work with a mag ?
is there any way to chage something to make it high presure?
thanks again

an LP tank wont work on a mag. mags require for best performance right around 800psi or more. However, if you have a gun that operates at a much lower presure like timmy's or newer angels then an LP tank is considered ideal.

Another thing to consider is that different regs will recharge at different rates just because of the way they are made. For instance, a pure energy screwin preset might recharge slower than a crossfire screwin preset at the same PSI. Same goes for direct output tanks like a maxxy or flateline. It depends stricktly on the design of the reg. Furthermore, you can have a screw in that potentially recharge faster than a direct out put

That is essentialy what I was saying..... Not talking about output pressures, but recharge rate. The higher the pressure the faster the recharge. Right? This being why an RT valve can recharge faster with a higher input on it. Same would go for a tank/regulator... the higher the pressure behind the regulator the harder the faster it can recharge.. maybe not?

The output is a property of the regulator and can be adjusted on some. Has nothing to do with the pressure in the tank. Besides when that pressure drops below the output of the reg, of course this will cause the output to be equal to that of the pressure in the tank.

Ahh, I see what you're saying. I thought you were talking about recharge rate of the regulator/valve on the gun. I would agree, the recharge rate of a 4500psi tank should be a bit better than a 3000psi tank, as the reg on the tank sees more pressure. I suppose the valve could have a faster recharge rate due to the 4500 tank recharging faster than the 3000, but who knows by how much.

[RTDynaflow]

Yeah, like Z-man said. A tank that can flow more air/sec will require less output to keep equal with a tank that flows less air/sec. I think that is what he was getting at...

Anycase, 4500psi behind the reg will recharge the reg faster and the reg will recharge the valve faster. How much will this matter? Meh, I don't think all that much. It is a greater factor of the output on the reg to the performance of the gun; versus the psi stored in the tank to assist it in recharging the reg faster, to keep the output as steady as possible - assisting recharging the valve. <--- make any sense at all to someoen other then me???

I am not sure, but I think this is why the DYnaflow tanks increase output psi as they get lower on air. To equal out the recharge rate of the tank dropping below 2kpsi. I am not a tech for Centerflag, so I could be very wrong here. That is what I came to logically.

Feel free to point out my faults here
