OFRF nexMESH Replacement Coils are made exclusively for the Wofoto Profile RDA . The nexMesh Replacement Coils is made with a perforated Kanthal A1 material with 3 times the mesh density of the standard Wotofo Mesh Style Coils. The increased density and surface area of the nexMESH micro weave netting design increases the heating speed and uniformity, guaranteeing consistent quality performance throughout the life of the coil. The micro weave design of the nexMESH coils also reduce spitback and hot spots. The mesh style coil sheet measures at 16mm by 6.8mm with a resistance of 0.13ohm and performs best at 60 to 70W.
