Apeks – Apeks Dst Din First Stage

Apeks Dst Din First Stage. The first stage – the powerhouse of your regulator – reduces the high pressure air stored in your cylinder to a controllable intermediate pressure of about 9 – 10 BAR. The air then flows along the medium pressure hose to the second stage (demand stage). Apeks manufactures a wide range of first stages to meet the needs of every diver. The DST first stage is one of the worlds top 1st stages with proven performance and reliability. The first stage is of pressure adjustable depth compensated diaphragm design and supplies air at exactly the right pressure. As the diver descends the demand for gas increases and to maintain the supply, the intermediate pressure increases relative to the water depth. In the Dry-Sealed System hydrostatic pressure, acting on the outer sealing diaphragm, is transmitted to the primary diaphragm via the load transmitter. These first stages utilize a unique over-tracking (over-balanced) diaphragm design, where the intermediate pressure supplied to the second stage increases more than traditional balanced models, as the diver descends to greater depths. This increased intermediate pressure compensates for the increased density of your breathing gas by allowing a larger volume of gas to flow through the system on demand. The result is superior breathing performance regardless of depth.The first stage is of pressure adjustable depth compensated diaphragm design and supplies air at exactly the right pressure. Specifications:- Dry Sealed System with swivel turret (DST)- 4 MP ports, 4 x 3/8 UNF- 2 HP ports, 7/16 UNF

Cressi – Cressi First Stage Mc5

Cressi First Stage Mc5. The MC5 first stage was designed completely in the Cressi Engineering and Development Centre.It is a balanced diaphragm first stage of an extremely moderate size and weight, which encompasses a high concentration of technology.A brand new sliding cylinder of the poppet, made from a special self-lubricating technopolymer minimises internal attrition and completely eliminates any possible oxidisation that could alter the performance of the regulator over time.The excellent performance has been improved even further by a special assistance chamber that triggers off a strong Venturi effect between the central diffuser and the intermediate pressure outlets.The hyper-balanced diaphragm mechanism not only maintains regulator performance when the pressure in the tanks changes and when diving deeper, but even improves performance in the notoriously most critical final phase of the dive.A sintered filter with a larger surface area withholds impurities present in the incoming air.The low and high pressure outlets are pre-oriented for optimum placement of the hoses.The very small cylindrical body is completely covered by an elastomer protective shell.It is quick and easy to pull apart the regulator for maintenance with the new INT yoke connection system or the internally threaded DIN connector.Technical specificationsHyper-balanced diaphragm first stageThree pre-oriented low pressure outletsOne high pressure outletSintered filter with larger surface areaFirst stage completely protected by an elastomer shellAvailable with INT yoke or with DIN 200/300 bar connectionWeight MC5 with INT yoke: 550 gWeight MCR with DIN connection 300 bars: 450 g

Scubapro Mk25 First Stage
Scubapro – Scubapro Mk25 First Stage

Scubapro Mk25 First Stage. SCUBAPRO is synonymous with piston-controlled first stages. Our MK25 underscores this heritage with an array of patented features and ultra-stable intermediate pressure, for an extremely punctual and consistent high delivery of air, ensuring unfailing performance. The MK25 balanced piston first stage is our absolute top performer, making this system our very best! Air balanced flow-through piston provides constant and effortless air flow unaffected by changing tank pressure. Newly polished chrome edition with 5 low pressure and 2 high pressure ports plus swiveling turret for convenient arrangement and personalisation of your gear. Anti-freeze protection for all diving temperatures and externally adjustable intermediate pressure for easy maintenance. Available in either 232bar INT or 300bar DIN configuration.Air balanced flow-through piston- First stages with air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter and more sensitive components, resulting in ultra fast breathing response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers and professionals. A balanced piston performs equally in warm and cold water environments. Two opposite high pressure ports- The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck. Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. High flow ports deliver about 15% more air than conventional ports. DIN/INT first stage configurations- To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 232bar INT version as well as 300bar DIN versions. Externally adjustable intermediate pressure- Allows authorized SCUBAPRO service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble the first stage. Chrome plated brass body- machined marine grade, for excellent resistance to corrosion and long lasting robustness. Cold Water Diving With SCUBAPRO- Diving conditions can be drastically different, including extreme cold water and ambient air temperatures, posing the possibility of a regulator `freezing`. Therefore, resistance to freezing is imperative for the diver. All SCUBAPRO regulator systems are CE approved for 300bar cold water diving. Some models go even beyond this super stringent qualification and have successfully been tested in extreme cold diving conditions at less than 2°C. As a specific anti-freezing measure, SCUBAPRO engineers have designed special anti-freeze components and features for the MK25 first stages for optimal cold water diving. The ribs act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled down by the gas pressure drop. For cold water diving, SCUBAPROs second stages feature precision molded carbon fiber and technopolymer valve housing and components. They even exceed the CE cold water norm. In addition, these components contribute to their lightweight features and corrosion resistance.

Scubapro Mk17 First Stage. MK17 FIRST STAGEA high performance balanced diaphragm first stage regulator, the MK17 has been engineered for harsh environments and for use in ice cold water or polluted environments. Resistance to cold has indeed been a key element in the engineering of the MK17. The Diaphragm Technology. Diaphragm-based first stages are environmentally sealed so that water cannot enter the inner mechanism. Bearing in mind that regulators generate temperatures up to minus 30°C due to the incredibly fast moving air and the pressure drop involved, it is imperative that sensitive moving metal parts avoid contact with extremely cold water. Therefore, diaphragm first stages have been the favoured choice of cold-water divers and those working in contaminated or muddy water.SCUBAPRO diaphragm first stages feature balanced technology and are packed with patented features resulting in ultra fast flow to the second stage on demand and a fantastic overall performance. Dry ambient pressure chamber, providing better performance in cold water than any other diaphragm regulator. The diaphragm design prevents the entry of water into the first stage mechanism and enhances a trouble-free operation, even in the coldest conditions. Patented finned cap with ribs increase surface area to maximise heat transfer from the water to warm the cold internal components. The balanced technology provides consistent performance at all cylinder pressures, at any depth and optimises the second stage performance, thus allowing for effortless breathing. Two opposite high pressure ports- The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck. Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK17 features four stationary low pressure ports, two of them HF. High flow ports deliver about 15% more air than conventional ports.
