Product Overview

25 years ago, Atomic Aquatics was founded with a mission in mind. At the time, Atomic Aquatics founders couldn't find gear that met their high standard of design, precision and performance. So, they decided to build it themselves. Fast forward, and Atomic turned the diving world upside down with their radical design philosophy and atelier iteration process. The results? Legendary quality and a bedrock commitment to building the absolute superlative in elite dive equipment and technology. Along the way, Atomic Aquatics changed the industry-and your expectations. From reinventing the BC with their radical BC1 and BC2 to creating the world's first titanium regulator, Atomic Aquatics engineered the technology, materials and ergonomics to achieve maximum performance. No matter the expense. All that said, when it came time to celebrate Atomic Aquatics 25th birthday, it only seemed right to flip the script again. Atomic poured their 25 years of manufacturing prowess into making something radically unique. That means ultra-premium construction, sci-fi level design and limited-edition exclusivity. So, you better be ready.

Representing 25 years of breakthroughs and breaking rules, the Atomic Aquatics T25 limited-edition anniversary regulator is a highly evolved version of the iconic T3 all-titanium regulator. To achieve the T25's unparalleled durability and performance, Atomic started with solid bars of titanium alloy and precision machined them to their super-elite specs. But they didn't stop there. To achieve radical durability, Atomic plated the T25's machined body with a new, proprietary diamond-like hardness coating (DLC) carbon nanostructure. The result is a burnt titanium that's stunningly beautiful, ultra-durable and 100% unique. In fact, with its rainbow-like burnt titanium finish, each T25 is highly exclusive-and no two regulators will share the same appearance.

The T25 forges a new titanium standard as the absolute finest regulator you can own, regardless of price. The T25 is Atomic Aquatics signature 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 T25 first stage has the features you have come accustomed to in an Atomic Aquatics regulator design. The T25 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 T25 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 T25 first stage yoke screw has a special 25th anniversary engraving and the body comes with a limited-edition serial number.

The T25 second-stage is a balanced linear flow design for extremely easy breathing at all depths and dive conditions. Like the first-stage the T25 second-stage is built-to-last with a titanium demand valve body, lever and sealing orifice. The diaphragm is made from high quality silicone rubber. This pneumatically-balanced poppet second-stage has Atomics patented seat saving dynamic orifice which unlike most second-stage orifices is a floating valve design which reduces wear on the second-stage poppet seat when the regulator is not pressurized adding life to this important seal.

The T25 second-stage regulator is equipped with Atomics patented automatic flow control (AFC). This unique diaphragm activated vain automatically controls the flow and venturi-effect of the second-stage for optimum breathing resistance at all depths. The second-stage does have a soft over molded rapid adjustment knob for rare special situations. If you have ever experienced the pulling effect of the regulator second-stage when you turn your head underwater, those days are gone with Atomics all titanium comfort swivel with a DLC coating, carbon nanostructure for unparalleled durability. Perhaps one of the most admired features of Atomic second stages is the patented comfort swivel which allows 30 Degree rotational movement without binding or kinking.

The T25 has a new high-flow second stage case and magnum lever design that significantly lowers breathing effort at any depth from shallow water to beyond the limits. A dual material second stage cover enables entire front to be used for purging and a dual silicone comfort fit mouthpiece with tear resistant bite tabs. The T25 has a metal accented front cover ring. The regulator comes equipped with a 3/8" threaded 32" (81.3cm) low pressure hose, weighs 1.7 lbs (771.1g) and comes with an owner's manual and travel bag.

The regulator and instruments are the heart of your life support system for diving. Want maximum protection for your regulator set-up, maybe with long hose, dive computer, and other instruments? Don't skimp on protection, use the Atomic Premium T25 Padded Regulator Bag with anniversary T25 iconography. Keep your regulators and expensive equipment separate from the rest of the gear. This bag is large enough to hold regulator, gauges, and an octopus. Fully padded bag measures 16.5 x 11.5 x 5" (42 x 29 x 13cm) with a volume of 1,129 cu. in. (18.5L) and is made of rugged 1050 Denier nylon. Bag features a reinforced, contoured rubber grip covered carry handle for comfort while carrying and comes equipped with a detachable, padded shoulder strap for ease of transport.

The Atomic Padded Regulator Bag boasts a padded internal compartment. The main compartment also features three more storage areas: a large, hook and loop closure pocket, a smaller mesh zippered pocket, and fully lined zippered pocket. There is an external zippered compartment for items you need close at hand. Regulator bag is black in color.
