Atomic Aquatics TFX Regulator



Atomic Aquatics TFX Regulator

The Atomic Aquatics TFX Regulator is designed for the diver who wants the most natural, effortless breathing in any diving attitude at all sport diving depths.
Atomic Aquatics engineers reimagined the rather unconventional front exhaust regulator design to create the most natural and effortless breathing regulator for all diving attitudes or positions. Traditional rear exhaust regulators have more breathing resistance in certain dive positions, like looking up.
The TFX gives divers enhanced and sophisticated air delivery with dramatically reduced inhalation effort compared to all other regulators on the market.


Atomic 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.


In extreme diving positions, like looking upwards, the TFX exhaust valve and diaphragm are positioned at exactly at the same level with no pressure differential. Any water will collect at the exhaust valve and be easily exhaled with each breath. The water column effect is minimal in the TFX, compared to the large water column effect in the conventional regulator, which will become more difficult to inhale since the diaphragm is higher than the mouthpiece. The TFX is much less sensitive to different attitudes encountered during diving.


The radical TFX design created engineering and design challenges that resulted in fresh case architecture – a complex series of fluid and natural geometries that integrate seamlessly with the narrow-width case and front cover. These unique forms were truly necessitated by function, such as finding an innovative way to route the exhaust from the front of the regulator to the rear. Form follows function with the sweeping flexible front purge cover and extended soft silicone rubber exhaust deflectors that route bubbles away from and behind the diver’s field of view.


The TFX is fabricated with many iconic Atomic Aquatics materials and performance features:

  • All-Titanium First and Second Stage metal components
  • Seat Saving Dynamic Orifice
  • Low-friction cap at the cam surface
  • Venturi Nozzle gear-driven tuning switch
  • Variable Lift Cam
  • New 4X Yoke connection first stage – one turn secures it to the tank
  • Comfort Swivel Hose now with less friction and smoother movement
