Oceanic Eos Fdx 10 Din

Oceanic Eos Fdx 10 Din. Every breath is a dream come true. For over 30 years, Oceanics R&D group has taken advantage of new materials, development of rapid prototyping, advanced computer aided design systems, objective testing, and lots of open water dives in an effort to develop a regulator with the lowest measurable inhalation effort in order to provide air to a diver at the extremes of human capacity.

When engineering brought the near complete EOS in for conformational testing the results were so astounding, the laboratory stopped testing and performed a complete calibration of all instruments, and in re-testing the EOS was found to have a near effortless inhalation resistive effort on test after test. Perfect.

Comprised of precision-machined components and extensive research and design, the EOS regulator has achieved an incredible feat-lifelike breathing. Oceanic-s gifted team of design engineers has included effortless breathing, inhalation effort adjustments, and comfortable second stage swivels and orthodontic mouthpieces into a regulator that you can hold in the palm of your hand. This is far more than just another regulator in the eyes of the Oceanic team, this is a dream come true.

- Pneumatically balanced second stage with virtually no breathing effort

- Diver adjustable inhalation effort

- Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive

- Ergonomic Adjustable Venturi Switch (A.V.S.) for simple Dive/Pre-Dive Adjustment

- Stainless steel inline swivel for reduced jaw fatigue and comfort

- Paired with the rugged FDX-10 Over-Balanced Diaphragm First Stage featuring DVT (Dry Valve Technology)


Pneumatically Balanced Valve.
The pneumatically balanced second stage reduces breathing resistance to near zero with a balanced valve seat designed to respond to the slightest inhalation.

A pneumatically balanced second stage actually has (or can have) the same initial crack opening effort as a mechanically balanced, but the spring force of a pneumatically balanced second stage is lighter so it-s spring rate is also lower. Therefore the force required to open the valve farther as flow increases is less than that required for a mechanically balanced second stage with a higher rate spring. So the total effort to breathe the pneumatically balanced second stage is indeed less.

The spring force must be just enough to overcome the difference between downstream air pressure and upstream balance chamber pressure.

The downstream air travels through a hole in the poppet into the balance chamber and applies an "upstream" force just slightly less than the downstream force.

Diver Adjustable Inhalation Effort.
Most downstream demand valve regulators are calibrated during manufacturing to a single, middle of the road operation. Whether finning up current at 100+ feet or merely snorkeling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment. A simple twist of the adjustment knob enables complete control... Set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.

Patented Dynamic Adjustment.
A common objection to adjustable second stages is that divers cant imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow. Taking another stride beyond common second stage engineering, Oceanic designed a patented DYNAMIC ADJUSTMENT feature into the heart of the EOS. This mechanically balanced valve maintains your preferred breathing resistance throughout the dive. Set it once and the EOS automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet - with no additional manual adjustment.

Ergonomic A.V.S. (Adjustable Venturi System) Dive/Pre-Dive Switch.
Designed to be unobtrusive, yet easily manipulated even with the thickest gloves, the A.V.S. deflector vane found in the EOS either diverts airflow from the valve to the mouthpiece, producing effortless venturi-assisted inhalation or creates enough resistance to prevent free flow on the surface.

Stainless Steel Inline Swivel.
Ever notice that nearly every picture you see of a diver, their regulator looks like it-s not the least bit comfortable- The EOS features an ergonomically designed stainless steel (no plating) in-line swivel for ultimate comfort.

Computer Optimized Design.
The EOS was designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development. The EOS-s unique valve, deflector vane and housing design directs airflow from the valve directly to the mouthpiece, producing nearly effortless venturi-assisted inhalation.

Patented Orthodontic Mouthpiece with High-Density Bite Tabs.
To further reduce jaw fatigue, the EOS features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.

Nitrox Compatible.
The EOS FDX-10 is classified as being suitable for use with Nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts.

FDX-10 Over-Balanced Diaphragm First Stage.
The Forged from marine-grade brass, the FDX-10 features optimized air paths and angled hose ports for superior performance and comfort. A sealed Balanced Diaphragm design, Enviro Kit and patented DVT (Dry Valve Technology) isolate all internal components from the environment. 2 high pressure and 4 low pressure ports allow convenient and comfortable hose routing.

The FDX-10 high performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases. The center -pads- that the diaphragms act against are different sizes so the working area of the outer environmental diaphragm is larger than the working area of the inner diaphragm. As depth increases, more pressure is applied to the larger surface area of the outer diaphragm than would be applied to the internal diaphragm. The result is superior gas delivery under the most extreme conditions.

DVT (Dry Valve Technology)
Ever wonder why they call it a "dust cap" and not a water cap- Most dust caps are not designed to keep water from entering your first stage. Regardless of how carefully you may maintain your regulator, water entry is a much more common problem than most divers realize.

DVT is a revolutionary regulator technology designed to automatically eliminate moisture and contaminants from entering your first stage, even if the dust cap is accidentally left off. DVT eliminates corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers.

The perfect balance of power. Our diaphragm MK17 first stage teamed with our newly designed G250V second stage.


This exceptional second stage features a 35% improvement in breathing performance when compared to its popular predecessor: the G250HP. It-s a terrific cold water combination.

-G250V is a full metal system, composed of ametal inlet tube, stainless steel orifi ce, metal inhalation-resistance control knob, and a metal hose connector/heat exchanger.

-Serious construction for serious divers. New VIVA knob for easier Venturi adjustment. High-flow exhaust valve to reduce effort.


MK17

Full metal body and components guarantee less risk of freezing and the MK17 is environmentally sealed so water cannot enter the inner mechanism. Given that regulators generate temperatures down to minus 30º 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.

-Balanced technology provides consistent performance at all tank pressures, at any depth and optimizes the second stage performance, for effortless breathing.

-Dry ambient pressure chamber provides better protection and performance in cold water than any other diaphragm regulator.

-Balanced diaphragm design, with ultra-fast flow to the second stage, prevents water entry, enhancing trouble-free operation, even in the coldest or most polluted conditions.

-Finned cap with ribs acts as a radiator to increase the surface area of heat transfer form the water to warm the internal parts.

-Available in either 232bar INT or 300bar DIN configuration.


G250

The human breathing process is unique and individual, rather intuitive, and taken for granted at the surface. However, once underwater and dependent on a regulator, we suddenly realize how personal and unique breathing behaviors are and how important a regulator can be. The harsher the diving conditions, the higher the flexibility and response we demand from a second stage regulator. This is why at SCUBAPRO we have implemented diver adjustable functions on many of our regulators

The SCUBAPRO G-Series is embodied in the G250 Vintage, a timeless classic which stands for unfailing performance and ultimate reliability. The choice for demanding divers.

SECOND STAGE REGULATORS

A second stage regulator must translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.

The designation balanced and classic downstream are also distinguishing marks for second stages and again imply ultimate flow performance and stability in addition to reliability, simplicity and solid performance.



SCUBAPRO introduces the G250V: Back and Better than Ever!

Our renowned G250 balanced adjustable 2nd stage is back and better than ever, redesigned as a Vintage version with tons of technical improvements.



-G250V has improved the breathing performance by 50%. Working inhalation & exhalation are easier and stress free. Comparing the G250HP which required 1,29 Joules/Ltr with the new G250V requiring 0,68 J/Ltr means you spend less energy to breathe the same volume of air.


-G250V is a full metal system- composed of a full metal inlet tube, metal orifice, metal knob plus a metal hose connector/heat exchanger. Serious construction for serious divers plus high cold-water resistance.


-New self contained cover concept- reminiscent of the classic G250, but much stronger for years of trouble-free diving. Also easily dismountable even underwater, thanks to the new no-locking pin system. Keeps you in control, no matter what type of diving you enjoy.


-New VIVA knob- for easier Venturi Adjustment, even with thick gloves.


-G250V systems- like all of our regulator systems, are protected by individual serialization & a Limited Lifetime Warranty.

Scubapro Mk25 S600

Scubapro Mk25 S600. MK25 S600 REGULATOR SYSTEM

Our top performing balanced piston first stage paired with our high performance air balanced second stage this combination is SCUBAPRO-s ultimate regulator combination. The S600 truly matches the MK25-s characteristics and thanks to its adjustment possibilities, it adapts to all diving conditions and all diver preferences. Ease of breathing is the essence of this system.

-The MK25 first stage is our absolute top performer and is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air. The means instant air flow at any cylinder pressure and water temperature for a real carefree dive.

-Married with the air balanced high performance S600 second stage, this system is our top performer.

-Balanced flow valve provides constant & effortless air flow.

-Diver adjustable inhalation control enables personal adjustment of breathing effort.

-Diver adjustable Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive control switch and extra high flow exhaust valve account for easy inhale & exhale.

-Super-flow hose for smooth air delivery.

-Precision moulded, lightweight components and anti-freeze materials provide high corrosion resistance and enhance cold water performance.

MK25 FIRST STAGE

THE PISTON TECHNOLOGY. The general advantage of a piston first stage lies in its reliability and reduced maintenance requirements, due to an effective but simpler mechanism with less moving parts. More importantly, no other design can reach the high air delivery rate of a balanced piston controlled first stage.

-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, SCUBAPRO-s 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.


S600
S600 SECOND STAGE

A second stage regulator must translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.

The designation balanced and classic downstream are also distinguishing marks for second stages and again imply ultimate flow performance and stability in addition to reliability, simplicity and solid performance.

-The air-balanced valve technology of SCUBAPRO-s S600 second stage features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage. This allows reduced spring tension and decreases the inhalation resistance to the lowest possible level. The result is super smooth breathing in all conditions. The air-balanced valve technology is featured in the X and S-Series second stages. For best results they should be combined with balanced first stages, like the MK25, MK19 or MK17.

-Precision moulded carbon fiber & technopolymer housing: low friction, light weight, corrosion and cold water resistant for long life & sturdiness.

-Diver adjustable inhalation effort. This feature enables the diver to adjust breathing effort via an oversized control knob it is available on the X650, S600, and G250V second stages. All other second stages feature a pre-set inhalation effort that suits the most common diving conditions and can be fine tuned at an Authorized SCUBAPRO Dealer on request.

-Venturi Initiated Vacuum Assist (VIVA). Another SCUBAPRO patented feature, the VIVA is available on all SCUBAPRO second stages. VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort. It is diver adjustable on all current SCUBAPRO second stages except the R295, since it is a second stage intentionally designed for diver training courses, rental facilities, and divers demanding ready to use equipment. A VIVA in MAX position gives powerful breathing support on every single breath a VIVA in MIN position helps to prevent free flow on the surface, for training, for buddy breathing, in currents, or when used as an octopus.

-Orthodontic mouthpiece. SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation. It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.

-Sturdy high flow hose with Kevlar lining for extra durability and flawless air delivery.

-Super high-flow exhaust valve provides the lowest exhalation effort and better breathing comfort.
