Atomic Aquatics – ST1 Regulator

Original price was: 34,495 ฿.Current price is: 31,000 ฿.

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
  • 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.Peak Performance Air-Balancing System
  • 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.
