The Uwell Crown 4 presents a new patented self-cleaning technology within the atomizer core of the new Crown line of coils, absorbing excess liquid into a condensation holder for later vaporization during usage. This helps reduce on wasted liquid and lessens the need to clean the detachable structure of the tank.
In addition, within the atomizers is the patented Pro Flavour Core Optimization System, or Pro-FOCS for short. This system recycles the in-taken air twice through the core of the atomizer to saturate the recycled draw with additional flavour from the vaporized liquid.
Also, the Crown IV Tank hosts a simplified quarter-turn threaded top fill system for faster refills and less downtime between cloud chucking sessions. Furthermore, the Crown 4 has a visually striking design, being hand-polished and knurled at the top and bottom ends, making airflow manipulation and unscrewing of the top fill system even easier.
