Product Description

Kayifun 3.1 Clone from Vapor World

The Kayfun 3.1 is easily one of the most popular rebuildable tank atomizers currently available on the market. The Kayifun was Designed in Russia and manufactured in Germany from solid stainless steel, the Kayfun 3.1 offers an array of beneficial features that help to maximize the vaping experience. This incredible atty has integrated adjustable airflow allowing for customization of the draw to suit your personal preferences, something that is uncommon with rebuildables. Keeping rebuilders in mind, the Kayfun 3.1 has been designed to facilitate the setup process with its easily accessible atomizer deck.


Setting the construction of the Kayfun 3.1 aside, it has superb performance. The reduced atomizing chamber helps to enhance the flavor of your favorite e-liquids. It has a juice capacity of 4.5 mL which will allow you to vape away for hours without needing a refill. The vacuum seal helps to prevent leaking and if flooding happens to occur the Kayfun has an overflow reservoir to collect any excess juice.

The Kayfun is a rebuildable atomizer designed to enhance the flavor of your juice. The Kayifum uses a chamber to house your wick and coil, which concentrates the vapor and produces a bold flavor. The Kayfun 3.1 features airflow control and a collection chamber to eliminate leaking into the 510 connection of your device. The Kayfun is made of stainless steel with an optional clear polypropylene window so you can see how much juice is remaining. Almost every aspect of this tank is adjustable, so you can achieve your perfect vaping experience. The Kayfun 3.1 comes with everything you need for your first build, along with replacement parts.


  • Airflow control, airhole, and fill hole on side

  • Clear window option

  • Screw on and universal drip tip options

  • Juice collector base


Additional Options-

  • Full clear tank

  • Bender - Angles drip tip

  • Provari collar

  • Extension tube for longer tank

  • Replacement isolators

  • Replacement clear window


Tips & Tricks-

  • When building, make sure your wick clears your air hole by at least 2mm. If your wick is laying against your airhole, it will cause your atomizer to leak. Also, minimize wick used. If too much wick is used, and it isn’t all sitting in the channels, it may also cause it to leak.

  • When filling, only fill from the top. Whenever you unscrew the top, you want to make sure you cover the airhole. If you do not cover the airhole, it will release the pressure held in the tank, and could spill all of  your juice. When holding your airhole and the top of your tank is off, fill down the side and continue filling until the juice is just over the threads on your atomizer, leaving a little gap to prevent pressure build-up. You then thread the top cap on slightly, then flip upside down, hold for a few seconds, and finish threading the top cap on.

  • You will want to clean your condenser cup every week or so. It collects heated juice and mutes the taste after a while. This is the piece that screws on directly above your wick and coil.

  • Don’t dry burn your atomizer for too long. If you do, it could cause your isolator to melt, which isn’t fixable. To fix it, you will need to replace the entire isolator.

  • Juice can collect in your collector base. To get it out, turn your device upside-down and fire it while blowing through your airhole.

  1. Awesome

    Posted by Dave on 17th May 2014

    Easy to build, doesn't leak. i moved up to this from an aspire nautilus....the flavor from the Kayfun is so much better, i highly recommend. I'll be buying another one with a polished finish, to match my mods.

  2. WoW

    Posted by DetraMental on 14th May 2014

    I absolutely love this RBA! It is so easy to build. I was a little apprehensive at all the parts it breaks down in to but once I put it together twice I felt a bit better about it. It vapes like a champ and there are no leaks!!

  4. great adomizer

    Posted by Unknown on 2nd May 2014

    great atomizer ,great price, on my 2nd coil build ,one horizonal ,one vertical both vaped great , removed the allen air ajustment screw and put it away because I got better air flow without it ,not as airy as my drippers but good clouds and flavor , only wish th juice filling was a litte easyer, but a little pratice and that will get better, best atomizer in my herd

  5. Good buy

    Posted by Andrew on 8th Mar 2014

    As long as you don't want to use the plastic tank on it as it is garbage, I have had two and both broke at the threads in less than a week using 50%VG/ 50%PG. Other than the plastic tank it is a great tank.

  6. Ok Product

    Posted by Mark Ski. on 18th Feb 2014

    This is an awesome Kayfun 3.1 replica! But lets do away with the rubber seals, and go with something better or add extra seals. I had to replace all the seals on the third day. Hciger we expect better from you.

  7. Great quality, fast shipping

    Posted by Unknown on 29th Dec 2013

    I ordered this as I wanted the hcigar clone of the kayfun. Price was right. The tank is amazing. Fit and finish are top. I have messed with a real russian and aside from the markings there is literally no difference. This one even has the better adjustable 510 connection that the russian has over the kayfun, where the pin doesnt thread directly into the block. Nice tank will buy more.

  8. Great RBA, Oh my the Flavor!

    Posted by ashad on 28th Dec 2013

    So the product comes in a nifty little carry case and you will find all the little pieces shown in the pictures. I have been using it for about 8 days now and am very impressed with the quality of the product and the vape. The flavor really does intensify in this RBA. Now, the threading is a bit crunchy and you must wash it thoroughly upon receiving it as stated in other reviews. Once the cleaning part is done, its super easy to set-up a coil and the crunchy threads are almost smooth in mine. I do not sub-ohm, so cannot tell you about quality of sub-ohm vape. The vendor is great and item was shipped the day after I ordered. Overall, this is probably one of the best clones of Kayfun 3.1 out there.

  9. Forget about expensive Kayfun and full size Russians!

    Posted by VapingDragon X on 27th Dec 2013

    This is the best "clone" I have found out there, if you own a Russian RBA and will like to have another one at a great price then this is for you, it is an exact replica down to the look and feel. My only advice is to clean it well before you use it as mine came with some residual metal scrap all over, but once cleaned and prime you wont be able to tell the difference. I'm ordering 2 more!

  10. Awesome replica!
