The Patriot Rebuildable Atomizer is made with precision machined components from the highest grade 303 stainless steel to ensure exact fits for consistent, even current draw to coils. It has a high volume tank which allows higher air flow for larger vapor production; more room for wick also means more juice for more hits. Precisely sized vapor ports allow laminar flow for a clean steady pull with no turbulence in the vape stream. Zero resistance press fit terminal post keeps the power constant on every hit. Unique dynamic quad ring seal keeps any extra juice inside the tank. Through hole terminal design guarantee positive and multi-point electrical contact to deliver maximum current to the coils. Dual o-ring design adds mechanical stability to tank and drip tip while keeping the air stream on the coils where you want it to maximize the vape. Unique heat sink fin design functionality removes up to 50% more heat during chain vapes.
