You cannot breathe directly out of a scuba tank because of the high pressure. A regulator reduces pressure to safe a level that can be inhaled by the diver. A diving regulator has two parts: the First Stage reduces the tank pressure and connects it to the Second Stage which contains the mouthpiece for breathing
The Loop 15X, a vertical revolution! Setting new regulator standards, the unique latest model from Mares represents true innovation!
The first vertical second stage ever, combined with the extremely reliable compact and performance of Mares 15X first stage. Featuring the DFC system, it meets all divers' demands at any depth. The chrome plated marine brass first stage regulator is a balanced diaphragm design which is inherently environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.
The 15X uses A.C.T. Advanced Coating Technology. This patented technology created to optimize performance, safety and reliability. The valve is covered with a hard polyurethane (PU) and the sealing surface is a layered with a soft PU for a perfect seal. Tri-material (brass, soft PU and heavy-duty" PU) reaches new levels of durability. The new valve is 600% more durable than its predecessor. Another unique feature of the first-stage is the dynamic flow control (DFC). The DFC system minimizes the intermediate pressure drop during inhalation. The 15X first stage guarantees a stable flow of air, even under extreme conditions. The First Stage is equipped with 4 LP ports with 3/8" and 2 HP 7/16" ports for attachment of a pressure gauge or air integrated console.
The Loop Second Stage is a vertical regulator design that can be mounted on the divers right or left, providing the ultimate freedom of movement with under the shoulder" hose positioning. This second stage is a mid-sized techno-polymer second stage regulator with its simple, yet reliable downstream demand valve design. The Loop's integrated Sagittal Vortex Assisted Design (S-VAD) system creates a swirling vortex with a low-pressure area in the center of the regulator that keeps the diagram down during inhalation, for very sensitive and easy breathing at all depths. The Loop also has twin exhaust valves for ease of exhalation and oversized silicone rubber purge button for easy clearing of regulator. Regulator comes with a 3/8" threaded low pressure hose, weighs 40.4 oz. (1,146 g) and comes with an owner's manual.
