These Cooling Fins are designed to efficiently reduce the amount of heat transferred from an atomizer or tank to the device they are being used with. This is achieved through the use of specialized fins that increase the surface area of the device between the atomizer and the mod, allowing for greater heat dissipation. By reducing the amount of heat generated by the atomizer or tank, cooling fins can help to improve the overall performance and lifespan of your device. Available in 22mm, 24mm, 25mm, and 27mm sizes and multiple colour options.
