About eXpromizer V4
The EXPROMIZER V4 is the fourth generation of the MTL RTA
designed in Germany. We have again set great store to design a RTA,
which has a easy and comfortable handling. This time, we have put the
focus on a top airflow to prevent leakage completely and make it easier
to use beginners. Of course, the experienced users also benefit from
Unlike other Top Airflow systems, we have designed an air supply that,
despite the top airflow, flows from below to the windings, a so-called
In contrast to the previous versions, the liquid channels have now
direct contact with the cotton and thus provide for even better liquid
flow. Together with the associated Liquid-Control, it is now easily
possible to use any type of liquid. In the smallest setting can be used
low viscosity liquids and liquids with a high viscosity can be used on
the largest setting.
Also the EXPROMIZER V4 retains the single coil deck like the predecessor
versions. Only a few small changes have been made to make the coil
winding even easier.
With the Top Filling Top Cap, the tank can be filled quickly and easily.
By closing the liquid control before filling the flooding of the inside
chamber is completely prevented and you can take time while filling.
