The Coil Art DPRO RDA is a 24mm diameter atomizer with a creative postless deck and length extended airflow system. There are four terminals at the base of the deck for coil leads that utilize side mounted hex screws and the 24K gold plating allows for greater conductivity. Airflow enters the DPRO RDA via two side air holes that measure 4.5mm in diameter and are adjustable. The airflow then travels down a length extended airflow system that is angled towards the coils for perfect airflow capability inside the RDA. Included with the DPRO RDA is an 8mm bore 810 ULTEM drip tip with a tighter draw than other 810 drip tips, allowing for enhanced flavor intake and a bottom feed pin that converts the DPRO RDA into a bottom feeding atomizer. Utilizing a postless, yet straightforward build deck, a smaller bore drip tip and airflow holes, the Coil Art DPRO RDA is the perfect RDA for those looking for a more flavor based RDA!
