The Hellvape x SMM PASSAGE RDA is a intricate vaping system developed in collaboration with Suck My Mod, incorporating a multipassage adjustable airflow control system, dual post build deck with innovative separation blocks, and comes with a new AG+ antibacterial and antimicrobial 810 drip tip. Constructed from durable stainless steel, the Hellvape PASSAGE RDA features a dual post expansive build deck on a 24mm base with two centered posts. Each post contains a single separation block that can slide vertically on a track, helping align coils to make installation simple and easy. In addition, the airflow control system features a three slot construct that is further separated into 19 smaller honeycomb style airflow holes. Each passageway on the airflow contains 5, 9, and 5 holes, respectively throttling or opening the airflow. A track at the base of the top cap and edge of the build deck allow the airflow to remain pointed directly to the side of the coil structure no matter how the airflow is adjusted. Furthermore, the PASSAGE RDA comes paired with an 810 drip tip made from a new material called AG+ that is antimicrobial and antibacterial to maintain cleanliness.
