Fogger V2...WOW

[gdeal]

I've had my Fogger V2 for a couple of days. I have had flawless vape. No leaks, no shorts...nothing. It sits next to my kayfun Lite. Same juice same wick material, same ohmage....I find myself reaching for the Fogger.

The KFL is a great device, but gravity wicking (when set-up right) vs vacuum is more consistent.

did the channel locks and pliers leave some nice gauges?

Not too bad.

By the way, if you guys aren't getting electrical shorts and haven't taken the deck apart, I recommend keeping an eye on the positive screw underneath/inside the 510 connector base. If it starts to lean towards one side, you could be having problems soon enough. Of course if the thing won't fire when you press the button, your APV starts getting extra warm, etc... stop, take the battery out and do your diligence.

So those that have taken it apart, what modifications are you doing? (mine hasn't arrived yet)

i found a couple small leather straps. i'm going to lock vice grips on with the leather straps next time i rebuild, that should get it apart without scratching it!

My Fogger kept shorting out on me and heating up my batteries. Taking apart the deck/base revealed an overly compressed positive post bottom that was causing the shorts. Check back through the thread and you'll find a description of the situation and a solution to it.

They arrived

I have the first one done

Good news my Fogger came in. Bad news my SS rope did not. So my first build was with cotton yarn and working great.

My last post was about 2 hours into using the Fogger V2. Now 5 hours in, it still has had no dry hits, or flooding. It looks amazing on top of an SVD....like it was made for it. However, it seems I am starting to get a rubber taste as others have described. Before I put my coil in, I noticed that the center insulator did not seem to be sticking up like some others have had, it looked to sit just blow the deck surface. I also made sure my coil sat above the coil legs to keep maximum distance between the deck floor and the coil.

Anyway so now i am going to disect my other one and see if I can figure out what may be wrong. If anyone has some other ideas/tips, please share.

Just to be sure, both the Kayfun and the Fogger work the same way as far as wicking and why they don't (shouldn't) leak

Scott, What kind if cotton yarn? Can u post a pic?

 

[ScottP]

It's Peaches & Creme Brand from Wal-Mart 100% cotton that has been boiled for 20 min. It's the same setup I use when rebuilding EVOD and ARO BCC heads. Since my Fogger is still pretty full I'll have to get a pic of that coil later, but it basically looks like the pic below which is an EVOD head. I do make sure to cut the wick flush with the housing after replacing the chimney.

I've built my Fogger a few times, and can't get it to wick quite well enough for subohm coils...0.9 is the lowest I can go without dry hits all over the place. Tomorrow I will try a hollow 635 mesh wick with the Petar K method as well as cotton microcoils.

 

[ScottP]

Ok out of two Foggers one is working great other than the taste from the insulator. The other one was shorting straight out of the box and I have taken it apart and put it back together probably near 30 times, each time trying different insulators in different spots, and even removing and reseating the whole positive pin. I did try using the half o-ring under between the base assembly and that double post middle piece. No matter what it's shorting without even putting a coil in it. ONCE, I finally managed to get the whole base together with no shorts, threw a coil in it and got 2.4 ohms. Then I realized the air flow wheel was stuck open so I tried to get that to close a bit, uh-oh unscrewed the whole air flow assembly from the deck assembly about 1/4 turn. Tightened that back down and made sure to turn just the air flow ring...with virtually NOTHING else to hold on to. Now it's back to short city. There is something seriously wrong with the way the air flow assembly, my deck assembly and my positive pin are put together.

On a side note, the entire positive post can be easily removed once you have the air flow assembly removed. It just presses straight down though an insulator similar to the one on the middle post.

Sorta of the same by working off pressure differentials but subtly different on the mechanics...

Here is my understanding of the differences. To get ejuice to the KFL wick, it needs you to puff (vacuum) that will pull juice into the atty chamber which will then saturate the wick. When you stop your puff, pressure balance occurs after juice is absorbed by the wick and air is brought back into the tank (big bubbles). The horizontal and vertical channels design creates the air/juice lock mechanism.

The Fogger allows ejuice to flow into the wick until the wick is saturated (gravity). Saturation level of the wick determines juice flow/air exchange. Once the wick is saturated, the juice viscosity etc created the lock and vice versa. When the tank negative pressure is low enough, air will be pulled back in though the wick, but there is no pure juice or air lock because there are no channels. You dont really see big bubbles coming back into the tank.

A fogger can leak if not enough wick material is placed in the slots to the tank. A KFL can leak if not enough wick material is covering the the air channels and you lay it on its side. But if you have too much wick material in the Fogger slots you can choke off the auto regulating pressure mechanism, with the KLF this is not so much of factor.

So if you have both devices/coils set up right. I think the main factor for juice flow for the KFL is the vacuum you create with your puff. With the Fogger its the amount of wick material in the slot.

Same mechanics just slightly different layout(build), Oddy, kayfun, Taifun, Pro Tank, carto tank, they all work the same, pressure differential of the pressure inside/outside the chamber.
They all work the same way, to understand how they work is important to get them to work well and easily trouble shoot it's problems.
This (post) is not meant to be something controversial just enlightening.

 

[gdeal]

The mechanics are similar but not the same. Its only slight, but they are differentiated. The Fogger can saturate your wick without taking a puff. This is not the case with the KFL.

Same here..not trying to create any controversy. Really just having discussion.

BTW I like both devices a lot!

I just set up my second one, modded the wick slots with a 3 mm diamond bit.
Every time a take a drag a little bubble come out of the end of the wick.
These two Foggers are making all my other stuff look bad.

Isn't that amazing considering the devices you own? Amazing what they can crank out in China.

 

[dwcraig1]

How many ads are you allowed in the classies at one time? LOL
This device is a perfect example of what China can do. Instead of making 1 on 1 copies complete with stolen logos and pissing every developer off they should just develop their own using the known good stuff a their guide. There is no reason they couldn't do more high end stuff. A good example is Japanese company Honda, remember when the first Honda 50 came out ( oh I'm the only one that old maybe) but that was a game changer as Japan had a rep for making only junky stuff.
