That means the original Kayfun experience meats modern day. The Kayfun Prime is a pure “mouth to lung” rebuildable atomizer. It inherits the functionality and design language of the Kayfun 5, but the inner life has been completely redesigned and tuned specifically for MTL vaping.

Do not use oils or oil based fluids with the atomizer.

Please use the atomizer responsibly and the coils you’ve created at your own risk.

  • Airflow

    The Kayfun Prime offers an Airflow Control, that is externally adjustable in 6 increments from 1mm to 2mm airflow.

  • Liquid Control and filling

    The Kayfun Prime gives you the option to restrict or close off the liquid flow completely, by turning the tank clockwise. At the fully closed position, you can open the topcap to conveniently fill the tank from the top through the large fill port. An air pocket in the topcap prevents spillage, if the tank is filled beyond the maximum and ensures and optimal liquid flow. Two full turns open the liquid control completely. Thanks to SvoëMesto’s unique pressure based feeding system, this setting works for most builds, as it automatically feeds the right amount of e-liquid to your coil.

  • Build Deck and evaporation chamber

    The build deck has been sized to accommodate smaller builds that are typical for MTL use. The new air outlet distributes the available air stream over the entire length of the coil to eleminate temperature spikes and therefore create a better flavor profile.

    With the build deck the evaporation chamber has shrunk too, to condense the vapor and give you a rich and flavourful experience, even at lower wattages.
