The XPure is a 26650-sized atomizer from SmokTech. The unique airflow system significantly reduces leaking, especially when tipped or laid down on its side. The airflow tunnels through the deck underneath the coil into the dual-layer top cap, and comes in through an adjustable air hole in the side. The deck is ceramic to reduce the occurrence of short-circuits. There are 3 posts for dual or single-coil builds that are easily tightened with the included screwdriver. The airflow is adjusted by attaching the included tool to the airflow adjustment piece on the side of the RDA. Turning counter-clockwise reduces the airflow, and turning clockwise increases airflow. Everything is held securely in place for solid appearance and construction. The XPure 26650 is a great addition to any 26650 mod!
