Aspire Nautilus 3SR Vape Tank

Description - Aspire Nautilus 3SR Vape Tank

The Aspire Nautilus 3SR Tank is a 2ml MTL and RDTL clearomiser from Aspire, a brand with a long, well-earned track record in mouth-to-lung hardware. It builds on the original Nautilus DNA with a revised push-to-open top-fill system, adjustable bottom airflow, and a latticed metal tube protector that adds real durability without adding bulk. Two coils ship in the box, covering both a tight MTL draw and a more open RDTL style.

Connection is via a standard 510 thread, so it pairs with the vast majority of regulated mods without any adaptor or faff. Whether you're putting together a new MTL setup or adding a capable tank to an existing mod, the Nautilus 3SR covers the bases that matter most: clean flavour, easy refilling, and a draw you can actually dial in. Vaping 101 stocks the full Aspire range with fast UK delivery, so you'll have everything you need from one place.

Introducing the Aspire Nautilus 3SR Tank

Aspire has been building Nautilus tanks for over a decade, and the 3SR represents one of the cleaner iterations of that design. The core geometry is familiar to anyone who has used a Nautilus before, but the updates are practical ones. The push-to-open top-fill cap replaces the older twist-and-fill mechanism, making refills faster and considerably less messy. The AFC ring at the bottom rotates smoothly to adjust the draw from a firm, cigarette-tight pull right through to a looser, more open RDTL inhale.

The latticed metal tube protector is more than cosmetic. It protects the glass during everyday use and gives the tank a distinctive look that sets it apart from the standard Nautilus 3. Colours available are Black, Silver, and Gunmetal.

This tank suits a wide range of users. Switchers coming from cigarettes or disposables will appreciate the tight MTL draw and the straightforward setup. Everyday vapers upgrading from a pod kit get a flavour-focused clearomiser with far more coil variety. Experienced vapers get a reliable daily driver that pulls from the entire Nautilus coil series. Fast UK delivery from Vaping 101 means your tank and replacement coils arrive together, with no waiting around.

Why Choose the Aspire Nautilus 3SR Tank?

• Device type: MTL and RDTL clearomiser tank. MTL (mouth-to-lung) means you draw vapour into your mouth first, then inhale, closely mimicking how you'd smoke a cigarette
• Connection: Standard 510 thread, compatible with almost any regulated box mod or variable wattage device
• Capacity: 2ml, fully TPD-compliant for the UK market. TPD refers to the UK Tobacco and Related Products Regulations, which cap nicotine-containing e-liquid tank capacity at 2ml
• Top-fill system: Push-to-open cap for clean, one-handed refills without removing the tank from your mod
• Airflow: Adjustable bottom AFC ring that rotates to tighten or loosen the draw to your preference
• Coil compatibility: Full Nautilus series coil range, including BVC, Nautilus 2S, and mesh options across a wide resistance range
• Build: Latticed metal tube protector for added durability, available in Black, Silver, and Gunmetal
• Best for: Switchers wanting a cigarette-like draw, everyday vapers upgrading from pod kits, and experienced users looking for a dependable, flavour-focused MTL tank

The 510 connection and broad coil compatibility mean the Nautilus 3SR fits into your existing setup without any compromise on performance.

Compatibility and Performance

The Nautilus 3SR accepts the entire Aspire Nautilus coil family, giving you a genuine upgrade path as you settle into your preferred vaping style.

Compatible coils and wattage ranges:

• Nautilus BVC 1.8 ohm (10-14W) - tight MTL draw, closest to a cigarette inhale
• Nautilus BVC 1.6 ohm (7-11W) - MTL with slightly more airflow
• Nautilus 2S 0.3 ohm (23-28W) - more open RDTL draw, suited to higher wattage mods
• Nautilus 2S Meshed 0.7 ohm (20-25W) - mesh coil for enhanced flavour clarity
• Nautilus Meshed 1.0 ohm (13-15W) - balanced MTL with mesh-level flavour performance
• Nautilus Meshed 0.3 ohm (23-28W) - open draw, high wattage RDTL option
• Triton Mini Clapton 1.8 ohm (13-16W) - for experienced users who want a handcrafted coil feel

Included in the box: One 0.3 ohm Nautilus 2S coil and one 1.8 ohm Nautilus BVC coil.

E-liquid recommendations: A 50/50 PG/VG ratio gives you the best wicking and flavour from this tank. PG (propylene glycol) carries flavour cleanly and wicks efficiently through the coil; VG (vegetable glycerol) produces vapour. High VG liquids above 70% VG are too thick for the Nautilus 3SR's coil system and will cause dry hits.

Nicotine formats and strengths that work well with this tank:

• 10-20mg nic salts for heavier smokers or people switching from cigarettes. Nic salts deliver nicotine more smoothly at higher strengths, making them a natural fit for MTL tanks
• 3-6mg freebase nicotine for casual vapers or those progressively reducing their intake
• Browse nic salts or 50/50 e-liquids to find the right match

The tank produces clean, flavour-forward vapour. Tighter coil options prioritise flavour concentration over cloud volume, which suits MTL use well. No battery is included; this tank requires a compatible mod. Browse variable wattage mods to complete your setup.

The broad coil range means you can start with the included 1.8 ohm BVC for a tight, cigarette-style draw and explore more open options over time, all using the same tank.

Aspire Nautilus 3SR Tank Highlights

The Nautilus 3SR keeps the features that made the original range a go-to for MTL vapers, with a few well-considered additions:

• Push-to-open top fill for clean, one-handed refills without removing the tank
• Adjustable bottom airflow with a rotating AFC ring for precise draw control
• Ships with two coils covering both tight MTL (1.8 ohm BVC) and open RDTL (0.3 ohm 2S) styles
• Full Nautilus coil series compatibility, giving you a wide and well-supported upgrade path
• Latticed metal tube protector that adds durability and a distinctive look lifted from the original Nautilus design heritage
• Standard 510 connection for broad mod compatibility
• TPD-compliant 2ml capacity, available in Black, Silver, and Gunmetal

The combination of coil flexibility and a well-designed airflow system means the 3SR adapts to your preferred draw rather than locking you into one style.
