Atomic M1 Regulator

The Atomic M1 Regulator 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 divers.

Pair it with Atomic M1 Octopus.

M1 Monel Regulator

Atomic metallurgy expertise drives Atomic to design the M1 Regulator 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.

Environmentally Sealed

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, a surge-protected front cover, and a 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.

Radical Design

The Atomic M1 Regulator 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 both extreme and extraordinary.

Designed for Challenging Conditions

The Atomic M1 Regulator 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 fulfil virtually any need or diving scenario. The M1 is built on the same platform as the world-acclaimed Atomic T2 and B2 regulators.

Jet Seat Piston

The Atomic Jet Seat system has no sharp edges that can damage the seat over time. Instead, Atomic employs a conical seat and blunt-end piston.

Atomic valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure.
