FRONT EXHAUST VALVE POSITIONING
Atomic Aquatics engineers deconstructed every component of previous front exhaust regulator designs to reevaluate and reimagine function and performance. The genesis of the unique Atomic TFX design lies in positioning the exhaust valve in the center of the inhalation diaphragm and mounting both in the front of the regulator, which provides enhanced breathing performance and superior dryness not possible in a conventional design.
