OFRF NexMesh Pro Tank is upgraded and innovated based on NexMesh Sub-Ohm Tank, which is reflected in the coil. It is the world's first tank with a combination of mesh coils and parallel coils. The OFRF NexMesh Pro Tank is more compact than the previous generation. The diameter is reduced to 24mm. It is made of stainless steel. There are four capacity changes depending on the internally installed coil head and tank tube. When the tank is equipped with a single-coil head, the e-juice capacity of the use straight PCTG tube is 4.5ml, and the e-juice capacity of the use bubble glass tube is 6ml; when the double coil head is used, the e-juice capacity of the use straight PCTG tube is 3.5ml, and the e-juice capacity of the use bubble glass tube is 5ml. With its unique slide-action top cap design, refilling your favorite e-juice is a breeze. Adjustable bottom airflow will allow the consumer to fine-tune their comfort level when it comes to flow amount. The replaceable 810 drip tip on the top of the tank helps to convey the flavor. The key innovation of OFRF NexMesh Pro Tank lies compatible replacement coils, it is compatible with H15 coil, H12 coil, H11 coil, and H13 coil, and also supports H17 RDC coil option for DIY fun. The tank package comes with two new H15 Mesh & Parallel Coil and H12 Clapton Mesh Coil. H15 Mesh & Parallel Coil is a breakthrough design. It is a conical mesh coil that uses the same amount of material in a single-coil instead of having multiple individual mesh coils. It has a higher vapor generation, used to maximize the surface area, the airflow through the center of the coil can be maximized, and it makes wicking easier and further improves flavor production. The unique design of the H12 Clapton Mesh Coils allows users to experience more flavor and a long-lasting coil life compared to traditional mesh.
