The new Sherwood Oasis Pro is a completely new design and ready to provide you comfort and easy breathing in all diving conditions. The Oasis's new 2nd stage proprietary valve design has been tested in the most rigorous conditions and continues to perform extraordinarily well. Both in the laboratory and in conducted testing the Sherwood Oasis has stood up to every test. The proprietary Moisture Retention Vane does an outstanding job capturing exhaled moisture and returns it upon inhalation. No more cotton mouth with this regulator! The larger diaphragm and purge cover and responsive to inhalation provide easy breathing throughout the dive. And the diver operated Venturi control allow the diver to adjust the setting. The Oasis 1st stage is a completely dry and environmentally sealed 1st stage maintains a clean interior. No gels or liquids to seal the Piston 1st stage design.
The Oasis offers unprecedented comfort with the addition of moisture retention vanes which keep your mouth cool and comfortable during the entire dive. Innovation at its best is the way to explain the function of the Sherwood first stage regulator. The first stage regulator incorporates Sherwood's dry sealed spring. 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 dry seal 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 Oasis second-stage boasts a large diaphragm and exhaust vale for optimal response to inhalation and decreased exhalation resistance. Oasis's precision-ground stainless steel cam, delrin lever and resilient silicone rubber seat give smooth effortless breathing. Its high impact glass-filled polyamide housing for rugged applications make the Oasis regulator one great choice for any avid diving enthusiast. The Oasis is a dependable downstream demand valve design with a venturi adjustment lever to prevent free flow. The lever has a dive/pre-dive setting. Placing the lever in the pre-dive position will avoid unwanted regulator sensitivity while entering the water from the beach with long surface swims or when jumping off the back of a boat.
If you're a warm-water diver who gets that awful-feeling of dry mouth, you are going to love the Oasis. Sherwood has exclusively-developed two, second-stage moisture-retention fins for the Oasis that keeps your mouth cool and comfortable all dive long. Moisture retention vanes collect vapor from exhaled air and returns it to the diver on inhalation, Promotes hydration and reduces dry mouth effect, Sherwood's patented, moisture-retention fins allow you to direct air flow and optimize breathing characteristics to match any dive condition. The Regulator is equipped with a 3/8" threaded 31" (78.75cm) low pressure hose, is nitrox compatible to 40% oxygen out of the Box", and comes with an owner's manual.
