Has any one worked on controling air flow?

[Poppa D]

Draw: The rate at which the air flows through your device.

I would be interested in any ideas that people have tried, or use that control the draw on your ecig.

I have done a few things, and some do work. But all of my attempts so far are limited. I haven't been able to conceive of an adjustable control for the draw rate.

Changing the draw rate alters the heat, feel, flavor, even the TH. It may also change the stability of atomizers, I cant be sure, but likely.

What I have learned so far is if I slow, or increase the effort of the draw the vapor is thicker, warmer, and has more body.

please share your ideas.

i think so

dont you agree?

 

[Poppa D]

I see.
Ive been tinkering with an eGo cone and O rings. Just messing around. A carburetor needle and seat comes to mind, but that seems like a monster obstacle. Ive been tinkering with the cone but its finicky and none to precise.

Air draw is a big deal for me, as i like a really heavy draw. So below is what i use for 510 based atties. for 801 or 901s i generally use my GG, which has adjustable draw built in, although i expect something similar would work for them anyway.

Also like to appologise in advance if i am not referencing whoever first thought of this, cant find anyone myself, but not really looked that hard, and i am sure someone has posted this already somewhere.

Basically i use the condom from a 510 cartomizer, snip the end off, and then make a couple of holes in it. pop it over your atties, and job done. Adjust the number of holes, or rotation of condom on your attie to restrict airflow as much as you like. Some photos below ( I hope first time posting photos). A couple of variations depending what type of battery your using. For a EGO style i put some holes in the middle, for a box mod cut some airholes at the bottom. Anyway hopefully the photos make it clear.

Couldn't get all the photos on one post so here are a couple more.

So here is the finished condom on an ego style, and a slightly different version to fit on an integrity juice box from DaveP (genesis.me.uk)

they all work the same way though just rotate the condom to adjust the airflow.

My AFS v2 already has this feature; There are 8 holes and by turning the bottom ring you control how much air flow goes through the device. Works pretty well.

 

[Poppa D]

Elendil,
That looks like its on a buzz? I don't know much about AFS V2, if it uses a specific atomizer, is it proprietary to GG products, is it still produced, lots of questions. Does the AFS V2 effect your atomizers? That does look effective and very nice, thanks.

Jamestory,
Thanks for the illustration, I have been tinkering with the condom approach but I hadn't thought to perforate and turn to tune. I have been slipping down to cover the air slits and tweaking from there up and down. Thats an interesting approach, I will try it out. Thanks for your post.
Has controlling the draw effected your atomizers?

 

[Elendil]

The AFS v2 is made by GG. I know Rob at Vapor Kings - DSE801, DSE901, Joye510 and KR808D-1 e-Cigarette supplies is expecting more in the next week or 2. Yes that one is on a Buzz, I also have one on a 5v ST. You can use 901 attys or 808 cartos(my choice). Truthfully, since I have been using the v2 (about 4 months), I haven't really looked at any other self juicing units.

Use the force, Luke!

Sorry, couldn't help myself. Looks like a mini light saber. Specs on it?

Re: the OP. If you use the right design, you may be able to employ common air valves used on aquariums. Sounds like an intriguing concept you have there.

 

[Poppa D]

Nobodyatall,
Thats a good idea, a very good idea.

Elendil,
What atomizer thread do you have on your Buzz?

Thanks. Your idea of controllable airflow is good too. I'll use that in the future if you don't mind. It really does offer the ability to finely tailor the vape. Sounds very appealing.

901...........

I accidentally accomplished some flow control. I this thread I posted about a top-fed version of the design: http://www.e-cigarette-forum.com/forum/atomizer-mods/120072-atomizer-cartomizer-life.html. My top-fed version includes a flat "disc wick" wrapped around a C-shaped wire. If you line up your cartridge a certain way with the gap in the C-shaped wire, it results in easy air flow. Twist the cart a little and the flow gets more restricted. Just a nice unintended side benefit.

Hey Poppa, I have been using the condom method for months. cheap and easy. For a box mod, if the connector is flush. Just the irregular cut of the condom will give you an adjustability. On a reg bat if you notch a small v cut in the condom you can rotate it to achive desired draw. once the condom is set it doesn't move.

 

[SuZamme]

I know you all get excited about anything you can mod i.e. mold, cut, wrap, bend, and drill.

However, on the eGo, T-Rexx, Riva I just tighten or loosen the cone and it completely changes the air flow. On the other 510 devices, unscrewing the atty a bit also changes the air flow.

 

[WillyB]

Me I prefer an airy draw. Different strokes.

I also use the rubber grips off $ store pens for mouthpieces/drip tips. I have many, cut into different lengths and find the length used (usually dependent on the voltage/ohms) is also a good way to fine-tune the vape.

Sorry if I haven't revisited this thread for a while.

Recently I've been using the E2 cartomizers, XL and standards, and Joytech cartomizers. The E2's are very interesting devices.

The AFS v2 has the distinction of being the only marketed device available to control draw, but at the moment I will have to wait to try it.

Although I've used the condom sleeves, the ideas posted are new and interesting, thanks for sharing them.

I still visualize a very slim adapter that seals all air off completely and can be adjusted in a mechanical manner from no draw to full draw, like an adjustable air valve in a tire stem. The eGo/valve combo intrigues me.

The change in vapor production is a result of the change of internal pressure at the coil.
The harder the draw the lower the absolute pressure at the coil location.
The lower the pressure the lower the boiling point of the liquid.
The lower the boiling point the more vapor possible with the same battery.

harder draw = more vapor

As has been mentioned above, opening the holes makes it easier to draw but can reduce the vapor production.
I modded a passthru for better airflow and was disappointed with the results.

The imaginary ideal atty has low internal pressure without collapsing the lungs of the operator.

YMMV

Great thread, thanks...will try the mods. I use a finger over the atty "cutouts" on my 510 if I need a bigger hit. I got more vapor by using a 50/50 PG/VG mix too. But I'm just a beginner here.
