Introducing the Zephyrus Sub-Ohm Tank, UD's first entry into the Sub-Ohm Tank market that brings top level innovation, serious airflow, and the most sophisticated included RBA deck in today's industry. Featuring fully adjustable dual slotted airflow measuring 3mm by 6.5mm each, the Zephryus' 0.3 ohm dual coil head is manufactured utilizing Japanese Cotton for amazing flavor to complement the fantastic vapor production along with a high quality ceramic base. Replaceable coil heads are made the way we actually build (horizontal with the cotton on the inside). With a capacity of 5 milliliters, the tank can easily be filled utilizing a top fill method with more than ample space to fit various droppers and tips while ensuring a tight fit with the silicon seal. A widebore 510 shorty drip tip is included along with an additional heat-sink adapter to ensure minimal heat dissipation. The RBA deck features a split T-Post positive with massive dual 3mm airflow holes below each post to pair with ample wicking channels. Manufactured out of Stainless Steel and Glass, the Zephyrus also includes Clear, Red, and Blue sealing elements for personal touch. Balanced, versatile, and innovative. The UD Zephyrus Sub-Ohm Tank.
