The Asgard RDA is a top airflow 30mm RDA with a semi-post less design. The deck brings four 2.5mm x 3.0mm individual post holes for easy coil installation with a quick release squonk pin which makes swapping from drip to squonk mode extremely fast and easy. It’s unique airflow design is a key aspect to the vape experience it offers compared to other atomizers on the market. On the outside, the RDA is sporting 48 airflow holes offering massive intake into the 2nd stage airflow chamber to build pressure before it is diffused onto the coil. The air travels on a 30 degree angle through the ULTEM airflow difuser – pushing under the coil grabbing all the flavor your coils can create before it travels through the reduced chamber and up into the drip tip. (The flavor and vapour production is unmatched to any 30mm Vaperz Cloud atomizer we have done in the past.) Offering innovation on every level and an incomparable vaping experience – this is a MUST BUY for all vaping and cloud chasing enthusiasts!
