what is the lpc exactly for. I know what it is but what does it do to help my gun. I have a stock moded valve on my tribal.i am pretty sure i want one just wanting to know what it does. I do have a sonic lpr also as far as something help lower pressure.

Well the LPC is a chamber/volumizer what increase the available volume of LP air to your marker. It helps to reduce the operating pressure of your marker because there is more air your LP will not drop off as fast. It can help your marker in two ways: one more efficent operation since your using lower pressure you gain more shots per fill (how much, ummm don't know), also since you can lower your pressure from stock 105psi to 70psi (or thereabouts) the chances of chopping balls with your bolt is reduced, as there is less kenetic energy in the bolt.

If you have a Sonic LPR that is made for a Tribal then a LPC will not work as the LPC is designed to replace the AOC.

I have two other products that you may want to look at. TILPR and TLPRC

Quick question Edwin, I dont mean to steal this thread, but if my AOC is perfectly tuned(by andy), will a LPC change anything??? I know you say it's not required to mess w/ the aoc, but it makes more sense to me if it would change the pressure.

Yes and No, it will not change the LP but it will give a more consistant LP. What you may gain by having the LPC for AOC is a lower LP setting. If you want to play with the LP setting of the AOC, you can probably get it down to about 70psi with good results.

You will need an AOC gauge to do this.

would it really reduce the amount of air used??? Sure its at a lower pressure but doesn;t that mean you have to use a higher volume of air to accomplish the same task?

this is kind of a tupid laymans way of putting it and i am sure somone will give a more elaborate definitiong here but here goes.

think of say a simple 47/3000 tank.

that tank always has 47 cubes of air inside it. no mater what you do to it weather it is full or empty it always has that exact volume of air.

it does not always have 300 psi of pressure. the more you use it the lower the pressure drops...once it gets down to around 100 psi it is no longer of any use

so right there your already gaining a few estra shoots going from 100 to 70 psi...if it only had 70 psi, a marker that normally would require 100 would not fire yet one that only requires 70 would.

how much less it uses would be one crazy algebraic equation i would not care to even try to figure out but yes it lasts longer cause each shot uses less pressure...it is the pressure in an hpa that determines how long it lasts not so much the volume. not that a 68 does not last longer then a 45 but still the major difference is pressure.

take a 45/45 you can easily get 100 to 200 more shots out of it than you can a 45/3000

on a side note try running evil through a paintball marker that is smoking 400 fps...you shouldn't have it that high to begin with but lets just say you do..put it through a tippman or spyder and it will blow in the barrel.

put it through a freeflow autococker with a volumizer and running low pressure and it will not...high vollume and lower pressure gives more of a long gradual push out the barrel versus a short fast pop so it is also easier on the paint too.

w/ my lpr i would be tapping it into the asa and puting the lpc into aoc spot. Would they be useless using both together. So i get more shots per tank, lower shooting pressure required for gun to shoot.

You need an LPC for running an LPR from the ASA Adapter. Get the style that 'replaces aoc' in Edwin's page of components. take out the AOC, put that in, run LP hose to the 8/32" barb from the LPC, tune and your done.

but you have to have the special LPC to hold the Valve Spring in place.

YES, YES, YES!!!!

IT WILL!!!!

Reducing your High Pressure will save you more air then reducing your Low Pressure, but it does actually reduce your used air.

Goose was on a different track but not the track I was talking about.

You have to remember it takes the same volume to operate the marker, but since they are operating at two different pressures there is actually two different volumes. That sound bit funny --- how can the same volume be different.

Well lets say it take 1 inch^3 to push the ram forward that 1 inch^3 will stay the same no matter if your at 100psi or 60psi. So the result is 60psi*inch^3 versus 100psi*inch^3.

Same goes for High pressure and is easier to understand/imagine. If your operating at 300psi for 12ms and 150 psi for 12ms obviously the 150 is more efficent.



Another way to look at it is if you take a little bits of 100psi out of a tank (same amout of 100psi each time) then you may (let say) 10,000 bits out before your tanks empties, but if you take the same amount at 60 you should get more bits.

It is actually a Rate problem and of you took Calculus you would have studied this type of problem.

The thing that changes with lowering your LP is the speed in which the ram opens and closes.

If I put everything on paper I probably could explain it better, but I am lazy.

does it make the ram slower or faster???

Not sure if it makes it slow but the resulting kenetic energy on the ball and the valve is lowered. Therefore less ball breakage, which is the main reason you want lower pressure. If you can lower the cocking pressure enough to reduce or eliminate ball chops then your marker will perform better.
