What is a Caldera RBA?


The Caldera is VOLCANO’s pioneering re-buildable dripping atomizer and its revolutionary design is the culmination of years of research and development. It has been designed, engineered and manufactured in Hawaii, USA.

Machined out of 303 stainless steel, quality and resilience were top priority in its engineering. It’s three post design is centered on the idea of ease of building no matter the size and type of wire used, slotted post holes were also integrated into each post to ensure secure contact points for build leads. The positive center copper contact allows for maximum electrical conductivity along with better control of the resistance of any coil build.

Tirelessly tested through its many developmental stages, the final structure of the CALDERA is the perfected balance between refinement and function. A stainless steel wide bore drip tip is utilized to further increase the amount of air that can be pulled through the atomizer. The spiral design of the CALDERA’s cap evokes the form of a cinder cone volcano and is not only stunning but also purposeful.

The layered spiral form allows any condensation that forms inside the atomizer to fall back onto the coil so no e-liquid is wasted during any vaping session. The cap also gives the user the control over the amount of airflow allowed inside the chamber with a simple twist open or close, to ensure that the perfect stream of air from coil to inhale will result in the desired amount of vapor.
