RTA (Rebuildable Tank Atomizer) — a rebuildable atomizer (RBA) with a deck that has posts and is covered by a sealed metal chamber cap, around which is a tank reservoir for holding e-liquid. The chamber cap connects to a chimney that directs vapor to the drip tip. Gravity and pressure automatically force e-liquid in the tank down around the chamber cap and then up through slots or channels on the outer circumference of the deck. The wick ends are placed in these channels. As e-liquid saturates the wick, it is delivered to the coils to be vaporized.
The difference between an RDA and an RTA is the tank. There’s no manual dripping with an RTA.
