Patented Ducore®

Dual Ceramic Coils

Ducore lets you experience the complete flavor spectrum. Designed to deliver better hits, superior flavor, and power.

We’ve tested the coil hundreds of times with different testers, and as the testers of the dual coils, they all agree, that the Ducore delivers the goods. Along with a unique airflow system, Ispire has integrated into Ducore a patented anti-leak, anti-clog feature to ensure hassle-free performance. We know your oil costs a pretty penny so we worked endlessly to give the Ducore the best performance possible.

Revolutionary 3Fold
Leak-proof Design

Dual Ceramic Coils

Uniquely designed airflow system that not only provides unrivaled exceptional airflow but also a multi-channeled airflow design that prevents oil leakage by capturing it in the inner chambers.

To further help in the common leaking issues we incorporated a dense top and bottom cotton layer to prevent leakage from either end of the tank. To take it one step further, we installed an airflow shield on the outside to help direct and minimize a direct airflow, thus reducing backpressure. Combine all this together and you have a leading-edge patented industry tank with great airflow, and no leaking or flooding.
