  • Description

    The Atomic B2 regulator has received more accolades from the diving press and independent test reviews than any other regulator in history for both performance and ergonomics.

    The B2 shares the identical first and second stage design and performance as the T3- the most notable difference being the metal (titanium) used in the T3.

    It's compact high performance first stage of chrome plated brass and type 316 stainless steel.

  • Features
    • 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 (T2x/B2/ST1/M1)
    • All Atomic first and second stages are Made in USA with Limited Lifetime Warranty, and 2 year/300 dive service interval
