Choosing a sub ohm tank involves more than comparing its appearance. Coil compatibility, heating technology, e-liquid capacity, maintenance, and overall dimensions can all affect how well a tank fits your existing setup.
The Freemax Fireluke 4 and M Pro 3 are two sub ohm tanks that share several key features, including FM COILTECH 5.0 Double-D Mesh technology, a slide-to-fill top cap, and a standard 510 connection. However, they belong to different coil platforms and have distinct designs.
In this blog, we'll compare their main features and specifications to help you understand the differences before making a choice.
1. Mesh Coil Technology: What Do They Have in Common?
Both the Fireluke 4 and M Pro 3 use Freemax FM COILTECH 5.0 Double-D Mesh technology. According to Freemax, this technology is designed to improve flavor performance and heating speed by 50% compared with its previous technology benchmark.
The technology incorporates three main elements:
- Parallel Mesh Structure: The parallel arrangement is designed to provide a larger heating surface and more even heat distribution.
- SS904L Mesh: The use of SS904L mesh is part of the coil design intended to support consistent heating performance.
- Upgraded Tea Fiber Cotton Formula: The cotton formula is designed to improve e-liquid absorption and work with the mesh heating structure.
Although both tanks share this technology, they use different coil platforms. The Fireluke 4 is designed for X/TX/904L X Mesh Coils, while the M Pro 3 belongs to the M platform.
2.Coil Compatibility: Fireluke Series vs. M Pro Series
Coil compatibility is one of the most important factors to check before purchasing either tank. Even though the two models share the same core heating technology, their replacement coils are not interchangeable.
Freemax Fireluke 4 Tank - The Fireluke 4 supports Fireluke series coils, including X Mesh, TX Mesh, and 904L X Mesh options. This gives users multiple compatible coil choices.
Freemax M Pro 3 Tank- The M Pro 3 uses the M Pro series coils compatible and supports 904L M Mesh and M Pro Mesh coils, as well as the compatible M Pro RBA option.
Important: Fireluke series coils are not interchangeable with M Pro series coils. If you already own replacement coils, confirm the exact series before choosing between these tanks. This can help avoid purchasing a tank that does not match your existing devices.
3. Top-Fill Design and E-Liquid Capacity
Both tanks feature a lift-and-slide top-fill mechanism. To refill the tank, users simply lift and slide the top cap to access the filling area. This design makes refilling more straightforward without requiring the entire tank to be disassembled.
Both models also feature a child-resistant top-fill design and are listed by Freemax as ISO 8317 Child Resistant Certified.
In terms of capacity, the two tanks offer the same options: 5mL(Standard version) &2mL(TPD version). The 5mL version provides more room between refills, while the 2mL version is intended for markets where TPD capacity requirements apply. Actual availability depends on the version supplied in your market.
4. Dimensions and Weight: Which Tank Is More Compact?
Although the Fireluke 4 and M Pro 3 have the same standard diameter, their height and weight differ. The Fireluke 4 measures 28×50.5mm and weighs 59g. The M Pro 3 measures 28×58.85mm and weighs 72.2g.
5. Color Options and Appearance
The two tanks also differ in their available color choices. The Fireluke 4 is available in SS, Black, Blue, and Silver. The M Pro 3 comes in Rainbow, Blue, Gunmetal, and Black.
Both models offer familiar dark and metallic finishes, but the M Pro 3 includes a Rainbow option, while the Fireluke 4 offers SS and Silver options.
Which Tank Should You Choose?
Both tanks share similar core features, so the most practical starting point is coil compatibility.
Choose the Fireluke 4 if your current setup uses compatible Fireluke series coils or if you prefer its shorter, lighter design.
Consider the M Pro 3 if you already use M Pro series coils or prefer its taller profile.
Neither option is automatically better for every user. Your existing coils, preferred tank dimensions, and mod compatibility should guide your decision.
Final Thoughts
The Freemax Fireluke 4 and M Pro 3 offer similar core features but serve different setups through their respective coil platforms and physical designs. Before purchasing, confirm coil compatibility and check the tank dimensions against your device.
