Kayfun LITE

[gdeal]

as gdeal stated the white ceramic made for the kay-lite wicks as well as cotton, although I have not tried them I will have to agree with his assessment. I have seen all these wicking tests before which do show how well they wick vertical, the question is, is how fast they can replenish. I have tried every ceramic wick available and used them in genesis devices, all required tilting to some degree. the tilting made the juice travel along the outside of the wick and to the coil, this is not shown in wicking tests. I love the flavor using ceramic wicks, imo they are the best, next try, ceramic in the k-lite.

I have no idea why..... it will take someone who knows something about physics,but ceramic wicks better in a kayfun than in a genny. you can chain vape ceramic in a kayfun lite much better than in a genny.although I will add this caveat.....the breaking in of a ceramic wick is much more dramatic in a kayfun.....there is a real dramatic diffrence between a green wick and a seasoned wick.

From my observation of the white ceramic, what is different is that capillary rise is very quick for the first 20mm-25mm (much quicker than other materials) but then tails off above that. BJ43 did some wicking tests and showed that capillary rise height is less than 635 mesh, which makes sense due to smaller pore sizes in the SS mesh material. So with ceramics and gennies some tilting may be required

But in the KFL (and also in my ceramic Reo setup) juice absorption is almost instant. I'll see if I can put together a quick video tonight to demonstrate.

Ceramic in a genny is 100% capillary.
Ceramic in a KFL is 90% gravity fed pressure differential/10% capillary.

I'm not sure if I agree with your second sentence. The legs of my ceramic wick come down to the base just like a cotton legs would be placed. The absorption into and up the ceramic material is capillary. It rises just like any other wicking material. Maybe I am missing what you mean by gravity fed pressure differential?

I think it would be more accurate to say that the capillary action is greatly enhanced by the pressure differential, since the liquid is in a sense being forced into the ceramic.

That makes a bit more sense. But my understanding is that the negative pressure of your inhale pulls juice into the base of the KFL. The legs of the wick sit on/touch the base. Juice is then wicked up by the wick. When you stop inhaling, negative pressure in the tank pulls what remaining juice is left in the base plus some air (which should be around the same volume of juice that was either wicked or vaporized.)

There could be a situation where you have over primed your atty, but then juice would pool at the bottom where the legs are sitting. So it would still be capillary action.

I not certain that enough pressure differential from an inhale is possible to greatly improve capillary dynamics in the wick, unless you are taking some monster inhales, but even if you can do that, you will probably just flood out your atty.

How does that extra chimney work for large mode? From the looks of it, does it just slip over the stock chimney with an o-ring?

interesting to know for sure. its either the neg pressure helping it wick, or its just the fact that there are 2 tails feeding the coil and these 2 tails are shorter in distance vertically then the distance in a genesis device. either way its awesome that the wick keeps up, I would of never thought it so because of the slight tilting required in a genny.

gdeal, are you placing a little bed of cotton under the ceramic in the reo?

Same as the KFL ceramic. No cotton needed. But I guess it could be added for extra juice capacity. Here's a pic from today. That wick/coil is over a month old. Sorry for the OT guys.




I think the two tail short distance thing makes a huge difference.

that's really awesome, its like a sculpture. i got to get back into the ceramics.

In a genny your wick has to pull it's juice up from below as much as 1.5" vertical lift.

Ceramic in the KFL also pulls juice up from the bottom of the chamber, but not nearly as high, 1/2" at most? Because of the shape of the custom ceramic wick in a KFL, there is more vertical linear wick mass to carry the juice a shorter distance compared to a genny.

All other things being equal ceramic should be more efficient in a KFL vs a genny for that reason alone. The pressure differential merely keeps a constant (can I taste your) juice supply at the base of the wick. A genny at low tank level can dry hit if you happen to have it rotated wrong.

gdeal,

Have you compared side by side the ceramic to a micro coil/cotton in the yet......is the ceramic superior....or is it negligable..?

 

[JackSparrow]

Just received my Kayfun lite today from vape revolution, (vaperev), and wow is all I can say. I built it with 3mm ekowool with a .7 ohm coil consisting of a 2/3 wrap of 28g kanthal. I torched the ekowool before building, it took a couple mils of juice before the flavor came out but WOW!

The flavor is amazing, the vapor production is excellent and the throat hit is there! I'm going to have to step down from 12mg nic with this thing! It vapes better than I had hoped!

It's an amazing device for sure. After watching and reading many reviews, I finally understand.

I'm blown away by it. I definitely recommend it to anyone looking for a stellar vape!

Mine should be here tomorrow I can't wait.

gdeal,

Yes, I posted a comparison somewhere here around ECF.... but here is a recap.

Better (superior) is subjective; it really is personal preference, so the differences may or may not be meaningful.

So here are my thoughts. I would say the vape is slightly different. Cotton is a bit softer and wetter. Ceramic produces a bit fuller/thicker vape. Ceramic is a bit purer in taste but really only when a cotton wick is new and may impart a bit of cottony flavor. (some people say they never get the cottony flavor). Ceramic is much more durable and lower maintenance, but it really isnt that difficult to change out a cotton wick in a microcoil. With Ceramic wick, you get what you see, there is no guess/learning curve compared to how much cotton to use when making a microcoil. With ceramic, you really need to hot wrap the coil to get an optimal setup and that can be a pain to do, but you really only do it on the first set-up.

The differences are minor, they both provide outstanding vapes. I tend to push my coil/wicks a bit and sometimes chain vape to fast. This was increasing the need to do cotton wick change outs, with ceramic it sorta just sizzles out but the ability for the wick to wick stays the same. I also like the fuller vape vs the wet vape thing, so I prefer Ceramic. Sorta like how some people prefer silica or mesh or ecowool, etc...ya gotta try it, then decide if its for you.

Yeah your right,but ceramic in a genny is not dependent on just capillary, the tilt is very important, and the grooved wicks were a great improvement. at a certain point small diffrences make for real improvments.

In a genny your wick has to pull it's juice up from below as much as 1.5" vertical lift.

Ceramic in the KFL also pulls juice up from the bottom of the chamber, but not nearly as high, 1/2" at most? Because of the shape of the custom ceramic wick in a KFL, there is more vertical linear wick mass to carry the juice a shorter distance compared to a genny.

Anyone try Rene wire in the kfl?

What exactly is Rene wire and what are its benefits?

On a side note my KFL came in yesterday while I was at work, now I have to find the time and tools to shape a birdhouse white wick to fit.

 

[mcbender]

Been out In the field for 2 weeks looking forward to getting back in a week and finally building this thing!

 

[Vagabondnurse]

Dang! The mailman came yesterday to deliver my first KFL while I was asleep and now I have to go to the post office to pick up my package. Such is the life of a night shifter.

Rene 41 Wire

I haven't tried it. The microcoil thread has quite a few pics from those who have (not in a Kayfun though).

 

[turbocad6]

I'm using rene 41 in a kayfun mini with cotton wick, works pretty well, this is a 1.4 ohm coil











I've removed one of the smaller side cottons since these photos to increase airflow a bit, was a little choked with both
