🚀 Why the Nautilus 3SR Is a Game-Changer for MTL Vapers
💡 Intuitive Slide-to-Fill Mechanism
No more twist-offs or messy top caps. The Nautilus 3SR introduces a slide-to-open top fill system — one smooth motion, no leaks, no fuss. Just push, fill, and vape.
🌀 Precision 7-Point Airflow
The adjustable airflow ring features 7 fine-tuned airflow holes ranging from tight to slightly loose MTL. This means you get total control over draw resistance — essential for nicotine satisfaction and flavour optimisation.
🧪 Nautilus Coil Compatibility
Support for the entire Nautilus BVC range, including mesh and traditional vertical coils. Whether you prefer nicotine salts, freebase, or something in between, there’s a coil to match your style:
- 🟢 0.7Ω Mesh – RDL-friendly
- 🔵 1.8Ω BVC – Classic MTL draw
- 🔴 1.0Ω Mesh – Balanced warmth and flavour
Pair this with top nic salts from our collection and you’ll be in MTL heaven.
🧼 Easy Coil Swap – No Spills
Thanks to push-fit coil installation, swapping coils is a breeze. The tank automatically seals off e-liquid to prevent mess when changing coils — a perfect solution for users on the go.
💧 Leak-Resistant & Clean
The Aspire Nautilus 3SR’s enhanced sealing design and leak-resistant structure make it travel-safe and perfect for everyday use. Vapers tired of juice-stained pockets will appreciate its clean and reliable engineering.
