Rdta

Can someone explain to me how a RDTA works? I'm not real sure how that or a rta works.

RDTA's (like the Big Dripper) are usually just standard RDAs with a tank on top. The Big Dripper has a pretty conventional 3 post deck and reduced chamber. The tank section holds the liquid and has a tiny little hole placed just over the coil/wick, and has a big spring running through the center from the base to the top. The top acts kind of like a button and holds the drip tip, and when you press the top/drip tip in, it breaks the seal and allows air into the tank, which in turn pushes liquid through the hole at the bottom of the tank and onto the coil/wick. Every couple of puffs you just give the top a few pushes and that keeps your wicks saturated.

RTAs like the Kayfun and many others have the wicks constantly saturated with juice by allowing the juice to flow from the tank, through the juice channels and to the wick. When you take a pull, it makes the wick draw more fluid from the tank, depending on your airflow. That's why if your airflow is too tight, you can cause the coil to flood because you are creating a vacuum that ends up drawing too much liquid. If your airflow is too open, you get dry hits because the wick isn't pulling enough liquid to the coil.

There are probably tons of videos or other posts explaining how they work better than this but I hope that helps a little.
