The Keras MTA realises Atmizone’s multi-purpose tank atomiser concept: high-end RTA and top quality vape tank for factory coils, two in one.

The Keras has been conceived to fulfil the combined needs of those vapers, who want somehow to easily switch between sustainable factory coils and rebuildable deck.

With the rebuildable deck installed, the Keras is a top-notch quality RTA. It features a high-quality deck with a decent building space of about 10.50mm (diameter), designed to allow usual, horizontal type custom single builts, for consistent vapour volume,powerful flavour reproduction and hard hit.

The deck can easily be removed as an one-part assembly, and be replaced by an Aspire Atlantis/Triton or Vaporesso Target cCell factory coil, this way transforming the Keras into a vape tank for factory coils in just an instant.

The Keras Giga REV is the revised edition of the bigger sibling, which goes one step further: more compact size, less weight, also switching much easier from Nano to Giga REV and vice-versa, without sacrificing capacity.

The Keras is a top quality versatile tank, mainly for MTL (mouth-to-lung), that can also do the job for STL (straight-to-lung) hits. Suitable for a wide resistance range (sub-ohm up to higher res), temp control setups or any other wire setup, factory coils or custom builds.



  • Available in two versions of different size and capacity, Giga REV and Nano, also with the option to switch easily from Giga REV to Nano mode and vice-versa
  • You can go from Nano to Giga REV using this transformation kit. You can go from Giga REV to Nano, by only installing the Nano Tank Body.
  • The Nano Top Cap is now common between the two versions  – Nano and Giga REV share the same top cap.
  • High-quality rebuildable deck with a decent building space of about 10.50mm (diameter), for classic, horizontal type custom single builds.
  • Removable rebuildable deck section, switching from RBA to factory coils tank (Triton/Atlantis or Vaporesso target cell coils.)
  • Amazingly accurate air flow control ring:- for MTL (mouth-to-lung) in RBA mode (air adjusting from zero up to a max of D2.00mm – internal airflow tube diameter),
    – but also for STL (straight-to-lung) hits with a range of factory coils.
  • One-piece deck positive pole for RTA mode, gold plated self-adjusting positive pole for factory coils mode, to minimise voltage drop and peak performance for TC setups.
  • Easy top refill mechanism, by unscrewing top cap.

    The Keras Nano (with the RBA section installed) is a great little atomiser that gives great taste, even at a moderate 12 Wattage.
    The quality of the machining is great: even when it is still warm it can be easily taken apart but there are no wobbly connections (everything just fits nicely). It is very clever designed: simple, but with some smart decisions. A good looking tank where beauty is more than only skin-deep.

      Hey Eelco,

      many thanks for the positive comments! Hope you will enjoy the versatility and performance of the Keras Nano for a long time 😉

    The Keras Nano is simply stunning.

    Not just in aesthetics, but in function as well.

    My sweet spot used to be 1 ohm at 10 watts, and the Keras worked wonderfully.

    Then I got a more powerful device (Provape Radius), and now I build a 0.5 ohm coil, and run it at 25 watts.

    The Keras keeps up perfectly!

    And on those lazy days, when I don’t feel like rebuilding, I can pop an Atlantis coil in the tank!

    Easily one of the most versatile tank systems out there!

    I own one of each size, so I’m prepared for the day no matter which one I choose!

    Hoping for colored tanks soon, and maybe more beautiful Atmizone accessories for this device!

    After a few days use with 0.9 ohm factory cCell coil I can say it is a great atomiser! ????

      Thanks for the feedback Andreas! It is also worth trying the rebuildable mode – the taste reaches its peak there!

    I’ve been through them all – well, at least most of them. Amazed at the performance of the Keras. At first sight, it looks kinda understated, Bauhaus minimalist. It looks like no other but hold it and you get the first inkling that this is different . It is.

    Mount it, feel it, vape it and Quality smacks you right in the face ( yes, and that’s with a capital Q). It’s not just the performance that impresses, but the attention to detail, the ‘gravitas’ of the whole thing – (when was the last time you bought an aty with a choice of o-rings packaged with a 1:1 size index card so you can tell which one is which ?)

    Cons ? So far just one – not a fan of the clear drip-tip … still, they’re worse things in life !

    Team atmizone, big thank you – great product, great customer service – it’s been a real pleasure (and, frankly, a revelation).


    I came across ‘ by accident. So, just in case ‘’ reads this – how come you guys aren’t selling some of these products ?

    Great Atty!

    If you’re searching for a really tasty MTL, don’t look any further; this is the one! (Or an Erlkonigin, if you don’t mind sounding like Darth Vader… 😉
    Flawless engineering, and as already stated here, a minimalist and clean styling.
    Every part screws together smooth and nicely.
    Hope you guys are gonna do a stainless steel tank section/tube next to the glass ones (using tank crackers only, and dont like the sound of breaking glass 😉
    Big Thanx to Eelco too, his review pulled me into this one (send this man a goody bag, he deserves it!)

    Cheers Menno.
