Atomic B2 Regulator

The Atomic B2 regulator is Atomic's most popular regulator with the perfect combination of comfort, performance and style. The Atomic B2 regulator features a compact high performance first stage of chrome plated brass and type 316 stainless steel. The Atomic B2 is ergonomically designed to have the world's most comfortable second stage, making it so light in your mouth it almost floats. Nitrox compatible to 40% oxygen. The Atomic B2 regulator features 2 HP ports and 5 LP port swivel, self-lubricating HP piston seal system for low maintenance and service pressures to 4350 psi (300 Bar) with DIN first stage. The B2 second stage features all titanium components, Atomic's patented Automatic Flow Control, which automatically adjusts airflow at depth to maintain stable, comfortable breathing and an impact resistant second stage. An environmentally sealed first stage option provides freeze protection at low temperatures. Second stage comes standard in all Black with 6 color options available (Blue shown in photo). If you are purchasing multiple regulator components, such as a regulator, octopus, LP inflator hose and gauge console, your regulator set can be fully assembled and tested (pressurize & leak check) at no charge by a certified scuba instructor at Dive Pro before it is shipped to you.
