Atomic ST1 Regulator

Information

The Atomic ST1 Regulator is a high quality beautifully crafted regulator that delivers outstanding performance and looks great. The 5 ported swivel turret 1st stage is machined from a unique 316 stainless steel, unlike conventional brass 1st stages, which performs better and is kinder to the environment.

 

Swivel Turret

The 1st stage has 5 Low Pressure ports on a swiveling turret which allow the hoses to rotate around the first stage with the 5th port facing upwards. This gives added flexibility in hose routing prefered by many sidemount divers.

The 2nd stage also features a swivel ball joint on the hose that reduces jaw fatigue as the hose can route in at a greater degree instead of just 90°.

 

Titanium Parts

The internal mechanism of the 2nd stage uses the same Titanium parts as the T2 and B2 models which is stronger, lighter and has a greater corrosion resistance compared to brass or stainless steel parts.

 

The 2nd stage also features a Seat Saving Orifice that takes the pressure off the seal enhancing the lifetime and performance of the regulator. Inside the 2nd stage is a soft seal and an orifice pushed against it behind a spring which only opens when you draw a breathe. When disconnected from your cylinder the SSO pulls the orifice back relieving the pressure against the seat. As soon as the regulator is pressurised or submerged the spring reactivates to seal the 2nd stage.

 

Automatic Flow Control

The ST1 2nd stage features Atomic's AFC system that automatically interrupts freeflows before they occur by using a flexible venturi system that redirects freeflowing gas back into the 2nd stage to equalise the pressure.

Mine has just arrived, 3 days delivery to Sweden, Excellent. The reg itself is a work of art, fantastically made, if it breathes half as well as it is put together I will be a very happy bunny.

These superbly built regulators deliver in spades (and then some). Beautifully crafted, these regs are a joy to dive. I've used lots of regs but they don't come anywhere Atomic and they are superb in cold water too. Well worth the investment.
