Delro Electronics Ultima RBA

Engineered from 316L stainless steel, the Ultima RBA showcases Delro’s focus on machining quality and performance-driven design. Its standout feature is the split-wick deck system, which divides the wick into separate channels to improve juice saturation and maintain consistent liquid delivery to the coils. This unique layout helps reduce dry hits while maximizing flavour efficiency across different vape juice styles.

The build deck is designed for simplicity and precision, making coil installation straightforward while still offering a highly refined vaping experience. Airflow is one of its strongest points, with an extensive set of interchangeable airflow pins allowing users to fine-tune their draw from tight MTL to more open RDL settings with exceptional accuracy.

Fully Boro-compatible, the Ultima integrates seamlessly into standard Boro devices and bridges, making it a versatile upgrade for users who want a more advanced, customizable internal atomizer. The combination of controlled airflow, innovative wicking, and premium construction makes it a standout option for flavour-focused builds.
