About Genesis Atlas Regulator GR440

Innovation at its best is the way to explain the function of the Genesis first stage regulator. The first stage regulator incorporates Genesis Dry Air Demand (DAD). This simple yet unique design has a flow-by piston that mechanically balances the air of the first stage ensuring excellent breathing characteristics at full or low cylinder pressures. Balanced flow-by piston design, which is a "fail safe" mechanism, with a patented dry seal internal mechanism to keep the intricate components clean and contaminate free no matter what kind of environment you dive it in, constructed from marine grade chrome plated brass for long life and durability.

The DAD function allows the regulator is increase the intermediate pressure of the regulator without messy oils or grease as with more sophisticated designs. This added benefit makes the regulator virtually uncontaminated from the environment of salt, sand or chlorine internally, which makes it the choice of most repair technicians. The first stage is equipped with two 7/16" threaded high pressure (HP) ports and four 3/8" threaded low pressure (LP) ports for addition of gauges and LP accessories; this is one work horse first stage regulator. Tee - shaped design reduces regulator profile when mounted on tank minimizing opportunity to make contact with the back of the head. First stage has a high capacity inlet filter for smooth delivery of air to the second stage. The Genesis Atlas 2nd Stage is a reliable downstream demand valve design that delivers air effortlessly; its pre-dive/dive switch eliminates sensitivity when swimming through surf, jumping off the side of the boat, or fining in a current, yet allows high performance breathing when needed. Durability is assured with a non-corrosive ABS/Polycarbonate housing and a corrosion resistant passivated (302) stainless steel demand valve lever. The regulators orthodontic mouthpiece allows hours of comfortable breathing without jaw fatigue. Regulator comes with an owner's manual and is covered by a 24 month limited warranty.

            Shopper  Why Did You Choose This?
            RONNIE M  It looked like a good reg for my son. I am also a qualified service tech for these regulators.
            Shopper  Looking for the Genesis Blizzard Regulator; have had one for years but would like to purchase another one. We dive in temps as low as 28 degrees F. do you carry them?
            Shopper  Is the first stage balanced?
            ROGER W P  Yes, balanced and sealed. My service tech indicated I had made a good choice. Genesis is a sherwood product. I have used it in a 2 week trip to the Philippines and to Cayman Brac, over 50 dives. Breathes easy. I am pleased with the reg and would recommend it.
