Aspire Nautilus 3SR Tank is a 4ml capacity atomizer that combines the renowned flavor performance of the Nautilus series with a modern design, easy filling, and precise airflow control. It has been developed specifically for MTL (Mouth-to-Lung) use, as well as RDTL (Restricted Direct-to-Lung) use depending on the chosen coil.
It offers different usage options, ranging from a tight draw similar to cigarette smoking to a looser, vapor-focused draw. Thanks to the wide Nautilus coil compatibility, flavor, vapor production, and draw resistance can be adjusted according to personal preferences.
Featuring a 4ml e-liquid capacity in its standard version, the Aspire Nautilus 3SR is designed to require fewer refills throughout the day. The sliding top cap provides quick and easy access to the filling port.
When filling, please add the e-liquid into the side filling port, not into the central airflow channel. Ensure that the top cap is completely closed after filling is finished.
The adjustable bottom airflow allows for the draw resistance to be regulated according to the coil used and personal preference. A tight MTL draw can be achieved by narrowing the airflow, while a looser MTL or restricted direct-to-lung draw can be achieved by opening it further.
The 0.7Ω Nautilus 2S Mesh Coil included in the box is suitable for users who want more pronounced vapor and a more open draw. The 1.8Ω Nautilus BVC Coil is an option that operates at lower power, offering a tight and classic MTL draw.
0.7Ω Nautilus 2S Mesh Coil: 20–25W recommended usage range
1.8Ω Nautilus BVC Coil: 10–14W recommended usage range
During use, it is recommended to start at the lowest wattage value specified on the coil and gradually increase the power according to flavor performance.
The Aspire Nautilus 3SR is compatible with the Aspire Nautilus coil series and the Triton Mini Clapton coil. Thanks to different resistance options, you can choose between tight MTL, loose MTL, and RDTL usage.
When choosing a coil, attention should be paid not only to the resistance value but also to the wattage range specified by the manufacturer and the targeted vaping style.
The stainless steel body and protective metal tank tube provide the atomizer with both durability and a modern look. Thanks to the standard 510 thread connection, it can be used with electronic cigarette mods that have a compatible connection.
Since the diameter of the atomizer is 24.6mm, ensure that the top plate of the mod to be used supports this measurement.

After installing a new coil, apply a few drops of e-liquid to the cotton wicking ports of the coil. After filling the tank, wait approximately 10–15 minutes before firing to ensure the coil is fully saturated.
Firing the device while the coil is dry or exceeding the recommended wattage range can cause the coil to burn and result in a permanent burnt taste.
Do not allow the liquid level to fall below the feed holes of the coil. Follow the manufacturer's instructions for filling and coil replacement.
