The Atomic Aquatics TFX Regulator design is all about attitude!

The TFX name refers to Titanium Front Exhaust. This differs from conventional second stages which are configured with an exhalation diaphragm in the front and an exhaust valve in the rear. The placement of the inhalation diaphragm and exhaust valve centered in the front of the regulator offers some unique advantages for improved breathing and dryness. This unique reimagined and reengineered front exhaust design with all corrosion resistance titanium second stage metal components and a soft grip Venturi control knob that has a special tuning switch and a variable lift cam. Reversible low-pressure rubber seat for easy maintenance.

This unique second stage regulator has Atomics seat saving dynamic orifice and a low friction cap at the cam surface. Soft flexible front purge-cover, an extended silicone exhaust tee and boast a totally unique industrial design with fluid lines and geometries. Coaxial diaphragm and exhaust valve provide for 360-degree breathing effort. The second stage 3/8" threaded low-pressure hose is manufactured from super-flex medical grade silicone core.

The Atomic Aquatics TFX Regulator second stage is coupled with Atomics T3 all titanium first stage. The T3 forges a new titanium standard as the absolute finest regulator you can own, regardless of price. The T3 is Atomic Aquatics signature first stage regulator, providing you unprecedented reliability and performance. Amazing light-weight and dependable materials makes it the perfect choice for travel. You'll dive confidently in exotic locations, where service is hard to find. Atomic Aquatics was the first to design and manufacture an all-titanium diving regulator. This exotic metal was chosen for its absolute corrosion resistance in ocean water, its strength, and its amazing light weight.

The T3 first stage has the features you have come accustomed to in an Atomic Aquatics regulator design. The T3 is a balanced flow-thru piston design using Atomics jet seat high flow monel piston. Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance. The Atomic jet seat system has no sharp edges that can damage the seat over time, like most competitors' first stages. Instead, Atomic employs a conical seat and blunt end piston. Atomics' valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 3-years or 300 dives without service. Diving performance is superior at even low tank pressure.

The T3 is also freeze protected with a factory sealed first stage that also prevents contamination such as silt and sand entering the mechanism. The regulator is Nitrox ready for mixtures up to 40% out-of-the-box. The first-stage has 2 high-pressure (HP) 7/16" and 5 low-pressure (LP) 3/8" ports. The LP ports are on a swivel turret for ease of hose routing. The Atomic Aquatics TFX Regulator has a new and unique 4X yoke screw knob that tightens or removes with only one turn. The regulator comes equipped with a 3/8" threaded 32" (81.3cm) low pressure hose, weighs approximately 1.7 lbs. (771.1g) and comes with an owner's manual.
