Hi, another new member here! 2 months off analogs and loving this new vaping experience. I'm have an issue with my aspire bdc ets tank. From the get go it will vape awesome. After about 10-15 of vaping the drag starts to get tighter and tighter. I was wondering if I need to look at getting an airflow controller. Does anyone know if the kanger airflow controller will work on aspire tanks. Please let me know if anyone has has the same issue. From reading elsewhere I think it's a common issue.

I found the problem was the hole in the "plug" at the bottom of the atomizers, not the tanks. If you carefully pull out the plug (the tip that makes contact with the battery) with your fingers, you will notice the hole on the inside is much smaller than on the outside. This is the major air restriction.

Conveniently, a 1/16" drill bit fits in the hole from the outside and can be used to make the hole about the same size all the way through. I used a pin vise to hold the "plug" and another to hold the drill bit and bored it out by hand in a few minutes.

These plugs can be saved and just exchanged for the the stock plugs when you replace your atomizer.

Be careful to not push the contact wires into the atomizer when you push the plug back in.

Also, make sure you're not blocking an air hole on the tank because of the way you're holding it. I've done this a few times and wondered what went wrong so suddenly. :)

It pulls ok without the tank attached to the battery. It does it on both vv batteries itaste mvp2 and ego twist. I don't know what else it could be. I will try to make the hole in the plug bigger and see what happens. If anyone else has any ideas please do let me know. Only other option that I can think of would be an airflow controller, anyone know one that is compatible with the aspire tanks.

I just looked at some of my newer atomizers. I noticed the slot across the end of some of the plugs is much shallower than on others. The quality control is sadly lacking. A shallow cut slot will reduce air flow with the battery in place (and only with the battery in place), no matter how big you make the hole through the plug.

I would suggest looking for the deepest cut slot in your collection of atomizers and boring out that one.

You need to take longer pulls on these. It takes a bit longer for the coils to get up to red hot. If you take a lot of short pulls, the coils will collect unburnt eliquid, and plug up. If the pulls get tight, pull on it for at least 5 secs to get a mini burn out. You'll get a bit of a burnt taste, and then the pulls should be easier. Repeat if needed. I find these coils gunk up very quickly and need cleaning a lot. Cleaning is easy... remove the top silcone grommet, boil in hot water for 10-15mins, dry for a least 24hrs. Dry burn until smoke stops. Fire until coils glow, blowing into top, release button and continue blowing until glowing stops. You will now see a grey residue on the coils. You just cooked the collected junk off the coils. Boil again for 10-15mins. Dry for 24 hours. Load it up, fill the tank and let it sit 5mins, and use. It should perform like new, although for a shorter period. Repeat when needed.

Before you worry about the slot, try enlarging the hole in the plug.

You can "measure" the slot with a 1/16" drill bit. Lay the bit down in the slot. In a "good" slot, when looked at from the side, the bit will go about halfway in (about 1/32"). With the shallow slots, the drill bit will only go about 1/4 to 1/3 of the way in.

I never tried boring out one of these shallow slotted plugs. If that's all you have, it may still work after boring. Of course, a deeper slot will be less restrictive.

Sandpaper will not work in any reasonable amount of time. A small file about the width of the slot should work fine. (A tiny "warding file" would likely be best.) A file this size is not a common household tool.


I've found the atomizers to clog much less frequently after boring out the plugs. My guess is that because less suction need be applied, there is less excess liquid drawn from the tank to burn on the coils and form deposits.

Cleaning (or replacing) is still needed after a time. I use a commercial grade ultrasonic cleaner with alcohol,* which finishes the whole process in one step, but few people have such things at home. I'm not sure if the cheap ones they sell for jewelry will work, but the boiling method is proven to work.


*WARNING: Great care must be used when a flammable solvent such as alcohol is used in an ultrasonic cleaner. The aerosolized solvent produced by doing this is almost explosively flammable. Keep all sources of ignition away and provide good ventilation!
