From the KF Lite User's Manual -

The e-liquid is stored in the tank system which is located between the walls of the outer chassis and the evaporation chamber. The evaporator chamber (2) has special grooves (1h) that serve as ducts for e-liquid to flow into the evaporation chamber which is mounted to the atomizer base (1). The tank is sealed and air tight when the cap is closed, so liquid does not flood the evaporation chamber through these grooves - air pressure inside the tank prevents it.

Drinking bowl for birds works on the same principle: liquid does not come out of turned upside down water-filled bottle if you keep bottle neck in a bowl of water. Water comes out of the bottle only when the level of liquid in the bowl drops below the level of the bottle neck - then some amount of water will pour out, fill the bowl up the bottle - and then stop again.

Another example: Take a straw, deep half of it vertically in the water, close the top opening of the straw with your finger and pull it out of the water. Low air pressure at the top of the straw will hold water in it, but as soon as you release your finger the sealing of the air bubble is broken, pressure equalizes and water discharges. Kayfun Lite works on the same principle.

When the user initiates the inhalation process, negative pressure is formed inside the evaporation chamber which draws a small amount of e-liquid through the grooves (1h) into the evaporation chamber where it gets absorbed by the wick located directly above these grooves. Low pressure is produced in the tank due to the transfer of e-liquid to the evaporation chamber. When the user has completed the inhalation process, the pressure in both the evaporation chamber and the tank are normalized due to the air being passed back into the tank through the ducts.

During the inhalation process, the evaporation chamber receives liquid from the tank through the grooves (1h) and after the inhalation the tank receives air from the evaporation chamber. This process can be visually observed as air bubbles rising from the grooves in the tank (provided the transparent ring is being used).

E-liquid that entered the evaporation chamber during the inhalation is absorbed by the wick. The wick is saturated and distributes e-liquid over the coil. The coil heats up and «atomizes» liquid. At the next inhalation this cycle is repeated until there is no more liquid in the tank or the battery is depleted.


Pretty ingenious if you ask me, I'm becoming more of a KF Lite fan everyday! See the bold text, for those of you with the KF Lite*, does this mean that you can hold your PV tip down (or button end up) and e-juice will not flood the coil chamber? That's what it sounds like to me - also sounds like a design unique to tank fed RBA's? I would think standard wicking would eventually saturate at the coil and start to drip, can't fight gravity. If this is unique to KF, then no reason why you couldn't adapt a nice properly sized & curved tube to the 510 interface and use the ELA as a long cylindrical pipe! When you're in one of those philosophical/reflective moods, or reading Henry David Thoreau :)

* Probably applies to all Kayfuns but I'm particularly interested in the KF Lite.

I'll take a crack at this...

This means that the inner evaporation chamber won't flood when standing upright due to fluid levels and pressure. The analogy is a little confusing but it applies. The bird bowl feeds liquid from the bottle outwards and stops when the fluid level surpasses the bottle mouth (and/or pressure is too low I think). The KFL feeds liquid from the tank inwards to the evap chamber and works similarly.

Since the KFL feeds inwards at the bottom, turning it upside down won't cause flooding either though since your juice can't reach the evap chamber grooves (which are now at the top). I guess technically it could leak if your wick couldn't hold the juice in the chamber but honestly, I've turned it upside down quite a few times and never had a problem. And the only time I've ever flooded my KFL was when I intentionally did it with primer puffs.

EDIT: Forgot to mention that vaping it upside down would eventually cause the wick to dry out since no juice would be feeding in.

Well maybe, I would like to see more comments. To me it's a pressure feed induced by inhaling, a slight vacuum is set up which forces juice into the channel up (or down depending on orientation) to the base of the wick. I don't think the wick would ever dry out as long as you had juice in the tank.

It is a vacuum fed, but you must have juice around the "vacuum holes" in order for it to feed. Since you have to have a slight bit of air in the tank itself, you will never have juice around the "vacuum holes" while being upside down. :)

Kayfun lite is good stuff, I still say I like the standard better, but mainly because I like a slightly tighter draw than what the lite provides. If you like a warmer vape, try the mini. Kayfun, no matter which version, is just some good good stuff.

Yep, you're both right - a picture is worth a thousand words! I had the atty orientation backwards in my head lol. Too bad, for a minute there I was ready for pipe mode! That would have done it for me too, now I'm back on the fence sheesh!

I traded my lite for a 3.1 due to the adjustable airflow, but yeah I will never touch another tank style atty except for my kayfun unless of corse David makes a better one (which i'm quite sure he could whip up). I'm a dripper for the most part, but when i'm on the road my kayfun is my go to.
No question the KF is a top notch unit, it could still be the one, I need to stew on it a little more :)

I have 2 Kayfun 3.1 - I guess only because having 3 would be ridiculous? Great devices - no question. Will be interested, of course, when David makes a topper. Kayfun gives a great vape and is SIMPLE - hope David beats that because to me, that is the mark.

More than 2 of an atomizer you know and love, I dont thinks so. I have 3 Odysseus V2 and if I finally get a working 510 base, I will have 4.

So...........Im ridiculous and darn proud of it.:D

Thats 2 atomizers for each ELA

That makes perfect sense to me. You have your primary ELA with primary Odysseus. You definitely need a back up ELA with its' primary Odysseus so you can drop, grab and go when the alien zombies are on your ... and you have no time to troubleshoot. Otherwise, you leave your backup ELA with primary Odysseus in tact, grab your 3rd Odysseus which is your backup to the primary ELA with primary Odysseus or backup to the backup ELA with primary Odysseus, AWESOME!

My batch 2 shipping notification has arrived too :rickroll::toast:

I ordered on 28th March so only just missed batch 1. There is now an envelope with my address on it so will hopefully get something in it soon!

Amazingly, my wife agreed to get it for my birthday and while I doubt it will have made its way over the pond in 10 days, it should be pretty close:)
