Atomic Aquatics M1 American Made Regulator With Lifetime Warranty!

The M1 is a balanced flow-thru piston design using Atomics jet seat high-flow Monel piston. Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance. The Atomic jet seat system has no sharp edges that can damage the seat over time, like most competitors' first stages. Instead, Atomic employs a conical seat and blunt-end piston. Atomics' 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. The chrome plated brass regulator is Nitrox ready for mixtures Up to 50% or oxygen mixes to 80% when special guidelines are followed out-of-the-box. The M1 is also freeze protected with a factory-sealed first-stage that also prevents contamination such as silt and sand entering the mechanism. The first-stage has 2 high-pressure (HP) 7/16" and 5 low-pressure (LP) 3/8" ports. The LP ports are on a swivel turret for ease of hose routing.

The M1 second-stage is a balanced linear flow design for extremely easy breathing at all depths and dive conditions. The M1 is designed for cold water diving featuring thermal heat sink and improved super-dry exhaust valve. The M1 second-stage is built-to-last with a zirconium plated brass demand valve body, titanium lever and sealing orifice. The diaphragm is made from high quality silicone rubber. This pneumatically-balanced poppet second-stage has Atomics patented seat saving dynamic orifice which unlike most second-stage orifices is a floating valve design which reduces wear on the second-stage poppet seat when the regulator is not pressurized adding life to this important seal.

The M1 second-stage regulator is equipped with Atomics patented automatic flow control (AFC). This unique diaphragm activated vain automatically controls the flow and Venturi-effect of the second-stage for optimum breathing resistance at all depths. The second-stage does have a rapid adjustment knob for rare special situations. The M1 has a new high-flow second stage case design that significantly-lowers breathing effort at any depth from shallow water to beyond the limits. A surge protected second stage cover for high current scenarios and a dual silicone comfort fit mouthpiece with tear-resistant bite tabs. The M1 has a super-wide exhaust deflector to disperse bubbles for enhanced visibility. The regulator comes equipped with a 3/8" threaded 32" (81.3 cm) low pressure hose. The regulator weighs 2.6 lbs. (1,191 g) and comes with an owner's
