Aspire Nautilus 3 Vape Tank

The Aspire Nautilus 3 is an MTL and RDL tank with a 7-point adjustable airflow system, sliding top-fill with child-lock, and compatibility with the full Nautilus coil range. 24mm, 510 connection, sits flush on most mods. Two coils in the box: 0.7 ohm Nautilus 2S mesh (pre-installed) and 1.8 ohm BVC.

What sets the Nautilus 3 apart from most MTL tanks is the airflow. Seven airhole sizes from 0.8mm to 3.0mm on a rotating ring at the base. That's not just "open or closed" - you can set it precisely to match the coil you're running. Tight cigarette-style pull on the 1.8 ohm BVC. Looser RDL on the 0.7 ohm mesh. Everything in between.

Works with nic salts and 50/50 e-liquids on higher-resistance Nautilus coils. The 0.4 ohm Nautilus 2S coil handles high-VG liquids if you prefer an open draw.

Aspire Nautilus tanks have been around for years for a reason. The Nautilus 3 builds on that with the child-lock fill system and the 7-point airflow.

7-Point Airflow System

Rotate the ring at the base of the Nautilus 3 tank to select your airhole size. Seven options from 0.8mm (very tight MTL, like drawing on a cigarette) through to 3.0mm (open enough for a comfortable RDL inhale). Each position clicks into place, so there's no drifting mid-session.

The airflow pairs with the coil you're using. Running a 1.6 or 1.8 ohm BVC? Set it tight. Using the 0.4 ohm Nautilus 2S? Open it right up. You're not stuck with a single airflow style.

Nautilus Coil Compatibility

The Aspire Nautilus 3 works with the entire Nautilus coil family. Two included in the box, and you can pick up any of these separately:

Press-fit installation. The tank has an automatic e-liquid shut-off valve that stops liquid flowing when you remove the coil - no mess, no leaking onto your mod.

Top-Fill and Child-Lock

Slide back the top section to reveal the fill port. No unscrewing, no removing the tank from your mod. The CRC child-lock means you need to remove the drip tip first, then slide the top cap back.

If you want slightly more capacity or just a replacement glass to keep on hand, grab a Nautilus 3 Replacement Glass Tube.

Why Choose the Aspire Nautilus 3 Tank

An MTL tank that doesn't force you into one draw style. The 7-point airflow gives you genuine control over how tight or loose the pull feels, and the full Nautilus coil range means five different resistances from 0.4 to 1.8 ohm without buying a different tank.

The child-lock top-fill adds safety without making refilling awkward. The shut-off valve keeps things clean during coil changes. And it fits any 510 mod at 24mm - no overhang on most devices.

If you already use the Nautilus 3SR, the standard Nautilus 3 swaps the metal tube for a slimmer profile with the same coil compatibility. Both take the full range. Browse all Nautilus replacement coils to find the resistance that suits your style.
