If you’re looking for more options, browse our full range of Rebuildable Tank Atomisers (RTAs).

Designed for both single- and dual-coil builds, the AN RTA allows users to fine-tune their vaping experience with interchangeable airflow rings and a dedicated single-coil chamber. Whether you prefer a restricted direct-lung draw packed with flavour or a more open direct-lung vape with increased vapour production, the AN RTA offers impressive flexibility.

Supplied with a lifetime warranty card, premium metal tin packaging, and a comprehensive accessories kit, this high-end RTA is built for enthusiasts who appreciate quality engineering and outstanding performance.

Built for Exceptional Flavour

The ThunderCloud x Coilturd AN RTA was designed with flavour as the priority, making it an excellent choice for flavour chasers looking for true RDA-level performance from a rebuildable tank atomiser.. Its reduced-chamber design helps condense vapour before it reaches the mouthpiece, resulting in richer flavour reproduction and improved saturation of your favourite e-liquids.

Combined with the precision side-airflow system, this results in a remarkably smooth vape that rivals many popular RDAs while maintaining the practicality of a refillable tank.

Whether you’re vaping dessert, fruit, tobacco or beverage profiles, the AN RTA delivers excellent flavour clarity across a wide range of coil builds.

Signature Postless Build Deck

At the heart of the ThunderCloud x Coilturd AN RTA is its spacious postless build deck.

The deck has been engineered to support both single- and dual-coil configurations, making it suitable for a wide range of vaping styles. Coil installation is straightforward, while the deck layout ensures excellent airflow distribution around the coils, improving flavour and vapour production.

For users who prefer a single-coil setup, the included single-coil chamber further concentrates flavour and improves efficiency.

Whether you’re using simple round wire coils or advanced fused Clapton builds, the AN RTA offers a highly satisfying building experience.

Pair the ThunderCloud x Coilturd AN RTA with our selection of pre-made vape coils to simplify building and achieve outstanding flavour and vapour production.

Interchangeable Airflow System

Unlike many rebuildable tanks that lock users into a single airflow configuration, the AN RTA includes multiple airflow options.

Included in the box are both a honeycomb airflow ring and a 3-hole airflow ring, allowing users to customise restriction, smoothness and flavour intensity.

The honeycomb airflow configuration provides an exceptionally smooth draw with reduced turbulence, while the 3-hole airflow ring offers a more direct and responsive airflow experience.

This level of airflow customisation allows users to tailor the AN RTA to their preferred vaping style. Whether running a single-coil or dual-coil build, the interchangeable airflow system gives users greater control over flavour density, draw restriction and vapour production.

Quarter-Turn Top Fill Design

Refilling is quick and simple thanks to the quarter-turn top-fill system.

A simple twist of the top cap reveals generously sized fill ports that accommodate most e-liquid bottle nozzles, reducing mess and simplifying day-to-day use.

The tank comes fitted with a standard 3.5ml tank section and also includes a larger 4.5ml tall tank section for users who prefer increased e-liquid capacity between refills.

Premium Construction Throughout

ThunderCloud has earned a strong reputation for producing high-quality rebuildable atomisers, and the AN RTA continues that tradition.

Precision machining, smooth threading and excellent fit and finish are evident throughout the tank. The included lifetime warranty card provides additional confidence, while the premium metal tin presentation makes the AN RTA stand out from typical rebuildable tanks.

For collectors, limited engraved editions are also available, with only 1,999 pieces produced worldwide in each engraved finish.
