Geekvape Z Nano 3 Tank – Adjustable Top Airflow & B Series Coils

The Geekvape Z Nano 3 Tank is a versatile, refillable sub-ohm vape tank designed to deliver excellent flavour, adjustable airflow and convenient everyday maintenance. Building on Geekvape's popular Zeus Nano range, the Z Nano 3 introduces an innovative push-to-open top-filling system, leak-resistant airflow design and compatibility with Geekvape B Series replacement coils.

Not to be confused with the original Geekvape Z Nano, Z Nano 2 or Z Nano MTL tanks, the Geekvape Z Nano 3 features an updated design with a 2ml UK-compliant e-liquid capacity, replaceable 510 drip tip and two included B Series Boost coils. Its standard 510 connection makes it suitable for a wide range of compatible vape mods, including the Geekvape Aegis Mini 5.


Geekvape Z Nano 3 Tank Key Features

  • 2ml E-Liquid Capacity – UK TPD-compliant refillable tank.
  • Push-to-Open Top Filling – Convenient refilling without completely removing the top cap.
  • Leak-Resistant Top Airflow – Designed to minimise e-liquid leakage while maintaining excellent flavour.
  • Adjustable Airflow – Customise your draw for DTL or restricted DTL vaping.
  • Geekvape B Series Coil Compatibility – Supports a wide selection of resistances and vaping styles.
  • Two Boost Coils Included – Pre-installed 0.2Ω coil and spare 0.4Ω coil.
  • Replaceable 510 Drip Tip – Includes an additional wider-bore mouthpiece.
  • Universal 510 Connection – Compatible with a wide range of suitably powered vape mods.


Push-to-Open Top Filling & Leak-Resistant Airflow

One of the most distinctive features of the Geekvape Z Nano 3 Tank is its convenient push-to-open filling mechanism. Unlike traditional screw-top vape tanks, the Z Nano 3 allows you to access the filling port by pushing open the attached top cap, making refills quicker and reducing the risk of misplacing components.

The tank also incorporates Geekvape's signature top-mounted adjustable airflow system. By positioning the airflow intake above the e-liquid reservoir, the Z Nano 3 helps minimise the likelihood of leaking while directing air towards the installed coil for consistent flavour delivery.

The adjustable airflow allows users to fine-tune their vaping experience, from a more restricted inhale to an airier direct-to-lung draw, depending on their chosen coil.


Geekvape Z Nano 3 Compatible Coils

The Geekvape Z Nano 3 Tank is compatible with Geekvape B Series replacement coils, offering a wide choice of resistances to suit different vaping preferences. From high-powered direct-to-lung (DTL) vaping to lower-wattage restricted direct-to-lung (RDTL) and mouth-to-lung (MTL) setups, the B Series range allows users to customise their experience without changing tanks.

The Z Nano 3 comes supplied with two upgraded Geekvape B Series Boost coils: a pre-installed 0.2Ω coil and a spare 0.4Ω coil.

Geekvape B Series Coil Options

  • B Series 0.15Ω Boost Coil (60–75W) – The highest-powered option in the range, designed for warm DTL vaping and substantial vapour production.
  • B Series 0.2Ω Boost Coil (50–58W) – Included pre-installed. Ideal for direct-to-lung vaping, delivering a warm inhale and generous vapour production.
  • B Series 0.3Ω Boost Coil (30–38W) – A balanced DTL option offering excellent flavour at a more moderate wattage.
  • B Series 0.4Ω Boost Coil (25–35W) – Included as a spare. Designed for restricted direct-to-lung vaping, providing a slightly tighter draw and reduced power consumption.
  • B Series 0.6Ω Boost Coil (15–25W) – A lower-powered option suited to restricted DTL vaping, producing a cooler inhale with more modest vapour output.
  • B Series 0.6Ω MTL Coil (15–25W) – Designed for users who prefer a tighter, more controlled mouth-to-lung draw.
  • B Series 0.8Ω MTL Coil (12–16W) – A lower-wattage coil designed for traditional mouth-to-lung vaping, particularly when paired with 50/50 e-liquids.
  • B Series 1.2Ω MTL Coil (8–12W) – The lowest-powered MTL option, offering a tighter inhale and reduced e-liquid consumption.

The upgraded Geekvape B Series Boost coils feature an improved mesh heating structure and wicking system, designed to provide consistent flavour and extended coil longevity compared with earlier B Series generations.

For the higher-powered 0.15Ω, 0.2Ω and 0.3Ω coils, we recommend high-VG e-liquids such as 70VG/30PG blends. Lower-wattage B Series coils, particularly the MTL variants, are generally better suited to 50VG/50PG e-liquids.

Please note: The Geekvape Z Nano 3 uses B Series coils, not the larger Geekvape Z Series coils. Always ensure your vape mod supports the recommended wattage of your selected coil.
