Nautilus – What is it in Vaping?

Definition

Nautilus is the brand name of a legendary series of mouth-to-lung (MTL) vape tanks and coils created by Aspire. Known for tight, cigarette-like airflow and rich flavour, the Nautilus range is the benchmark for beginner and MTL vaping in Australia. Whether you prefer Nicotine“>freebase nicotine or nicotine salt e-liquids, a Nautilus tank delivers smooth, satisfying draws with minimal vapour—ideal for discreet public vaping and recent ex-smokers.

Technical Details

The original Aspire Nautilus (2014) features a 5 ml Pyrex glass tank, adjustable bottom airflow with four precise holes (Ø0.8 mm – Ø1.8 mm), and a 510 connection. Coil“>Vertical Coil)”>BVC (Bottom Vertical Coil) technology uses Cotton“>organic cotton wrapped around a Wire“>nichrome wireheating element, providing even heat and longer life. Coil resistances range from 0.7 Ω (18–23 W) to 1.8 Ω (10–14 W). Later iterations—Nautilus Mini, Nautilus 2, 2S and Nautilus GT—shrink capacity to 2–3 ml to meet TPD laws, add top-fill, and adopt wider bore drip tips for optional restricted-direct-lung hits. All coils are cross-compatible across the series, making upgrades simple.

Usage & Tips

• Prime new coils with 3–4 drops of e-liquid down the centre, then fill the tank and wait 5 minutes to avoid dry hits.
• Start at the lowest recommended wattage; increase gradually to find your sweet spot without burning cotton.
• 50/50 PG/VG juice or nic salt blends up to 20 mg/ml work best; high-VG liquids may cause leaking or wicking issues.
• Clean the tank weekly to remove condensation and e-liquid residue, extending coil life to 10–14 days.
• If gurgling occurs, invert the tank and blow gently through the mouthpiece while firing at low wattage to clear excess juice.

History & Context

Launched in 2014, the Aspire Nautilus quickly became the go-to MTL tank for smokers transitioning to vaping. Its reliable BVC coils influenced industry standards, and the platform remains popular today—even as pod systems dominate—because of cross-generation coil compatibility and consistent performance with both freebase nicotine and nicotine salt formulations.
