EXTREME PERFORMANCE. NO COMPROMISE.

The M1 has an expanded performance range to meet almost any diving condition imaginable. Caves, cold, deep, enriched air – the M1 is perfect for recreational divers ready to extend their capabilities or accomplished technical and specialty divers. State-of-the-art metals meet proven Atomic designs to deliver reliable performance to fulfill virtually any need or diving scenario.

M1 MONEL REGULATOR

WHY MONEL? UP TO 80% EAN. THAT’S WHY.

Atomic metallurgy expertise drives us to design the M1 for extreme diving. Monel parts are used internally in the first stage for high strength, corrosion-resistance and oxygen compatibility. 316 Stainless Steel, multi-layer Zirconium-coated Brass, and Titanium are used throughout the second stage. The M1 valve body is Zirconium/Nickel over Brass and the Seat Saving Dynamic Orifice is Stainless Steel. The M1 is factory-ready for EAN mixtures up to 50% or Oxygen mixes up to 80% when special guidelines are followed.

COLD WATER. DEEP WATER. ROUGH WATER.

The M1 first stage is chrome-plated brass and environmentally sealed at the factory to encase key internal components made of Monel. The second stage features a thermal heat sink for cold water, and a surge protected front cover and super-dry exhaust valve for rough water. Add a super-wide exhaust deflector and an exclusive Atomic engraved heat-protecting jam nut for freeze protection to cover almost any extreme diving situation.

ENVIRONMENTAL. ERGONOMICAL. RADICAL.

The M1 design includes the same Atomic ergonomic and performance features that rocked the dive world. Patented Atomic exclusives like the balanced Jet Seat high-flow first stage piston, and second stage AFC Automatic Flow Control with Rapid Adjustment Knob combine to make the M1 not just extreme, but also extraordinary.

DESIGNED FOR CHALLENGING CONDITIONS

ENGINEERED BY ATOMIC FOR SPECIALTY DIVING – REC OR TEC

The M1 has an expanded performance range to meet almost any diving condition imaginable, whether Recreational or Technical. Accomplished specialty divers will appreciate this regulator designed to fulfill virtually any need or diving scenario. The M1 is built on the same platform as the world acclaimed T2 and B2 regulators.
