B2 FIRST STAGE

We understood that not every diver could afford Titanium. Even though every Atomic regulator has all metal second stage components made of Titanium, we designed an affordable first stage using brass. The Atomic difference is the performance, reliable design, and the durable chrome-plating process we developed.

Features of All Atomic Aquatics First Stages:

Compact size
Large, balanced flow-through piston design for stable intermediate pressures and high performance at low tank pressures
Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance
Service to 4350 psi (300 Bar) with optional DIN connection
Optional environmental seal kit for freeze protection at low temperatures
Nitrox EAN ready to 40% O2 (M1: up to 80%) from the factory with no internal modifications needed
CNC machined from solid bar material, the body maintains perfect alignment of the piston and seat to eliminate creeping intermediate pressure problems
Two high-pressure and five low-pressure ports on swivel cap (T3/B2/ST1/M1)
Two high-pressure and option of five low-pressure ports on swivel cap or seven low-pressure ports on fixed cap (Z2/Z2x)
All Atomic first and second stages are Made in USA with Limited Lifetime Warranty, and 2 year/300 dive service interval
