State-of-the-art metals meet proven Atomic Aquatics 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 Aquatics 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 Aquatics engraved heat-protecting jam nut for freeze protection to cover almost any extreme diving situation.
