MADE IN JAPAN〜Manufactured by DIVEWAYS〜
DIVEWAYS has designed and manufactured quality dive equipment in Japan since its’ founding in 1974. Products are made from select materials and are produced to exact specifications by skilled workers. We do not compromise on any aspect of production, resulting in high quality products and outstanding performance.
Our approach differs from competitors who may simply sell imported products to the Japanese market. Instead, our product design is directly influenced by feedback and opinions from the divers who use our product. We combine the latest technology with the feedback from our customers in order to continuously improve our product design and performance. The diver’s opinion and feedback will continue to drive our product development.
DIVEWAYS products have been effectively used and embraced by a wide range of divers with great success. This includes applications from leisure divers all the way to professional divers working in deep sea commercial applications. For all of these divers, there is a high level of confidence in our quality products produced from the best materials available and proudly made in Japan.
is a new design idea conceived around the basic concept that mechanical
or manual “countermeasures” can be activated by sensing any trouble or
breakdown as soon as it occurs. This approach is based on the concept
that any trouble with products can occur as a structural or mechanical
failure or alternatively, as wear and tear from too much use. In other
words, DIVEWAYS designs products with the idea that breakdowns or failures
can occur but that the products have guaranteed safety measures. In Japan,
this approach is generally interpreted as a multiple safety framework.
Multiple safety systems are only a part of the FAIL SAFE technology, and
DIVEWAYS sees FAIL SAFE as an integral part of the specialized equipment
made for the underwater environment.
The most important “lifeline” for a diver is the breathing apparatus and its primary component, the regulator. DIVEWAYS has devoted over 30 years of experience, technology, and attention to detail to development of its regulator. For example, in the first stage, the chance of the high pressure spring being damaged is extremely low (approximately within one in three million to thirty million).Only two cases have ever been reported.
Even though the possibility of damage
to the spring is very low, it is not zero and thus DIVEWAYS has adopted
a dual spring approach in furtherance of the FAIL SAFE concept. Having
two springs enables continuous air supply in the event of any roblems
with the first spring. In the event of any problems, the system is designed
to supply 71.11 PSI to the second stage. Because this pressure is . of
the normal pressure setting, the diver can immediately feel the difference
in the air pressure and may even have some discomfort in breathing. However,
the system is designed to supply enough air for the diver to safely ascend
to the surface. This proven dual spring system is part of all DIVEWAYS
The exhaust valve is also an important part of the air supply assembly. It must function in order to keep the system working properly. Some fatal accidents have been reported as a result of valve coming off because of damage on projection in center of valve. DIVEWAYS has patented a unique connection of all exhaust valves, including the one on the octopus, using the retainer prevents any accidental disengagement even the center projection being damaged. If any malfunctions do occur with the exhaust valve, trouble-free amount of water for breathing will infiltrate the second stage case, thus warning the diver to ascend to the surface for safety.
In addition, the concept of FAIL SAFE has been utilized even in the fixed diaphragm system of the dive equipment. This functional part of the dive equipment must work correctly in order for the diver to breathe. Instead of the typical system where the diaphragm is simply attached to the face, DIVEWAYS has produced dual attachments as an added safety measure.
In the second fixed system, a ring screw is attached to the face. A combination of a metal face and a metal ring make the second, outside case very secure, protecting it from any impact or compressive force. There has been one case of a diaphragm falling off (reported by CMAS) of a British navy diver as a result of this single fixed ring screw system. Based on its FAIL SAFE concept, DIVEWAYS has doubled the system’s attachments, preventing the diaphragm from ever falling off.
Also, if there is any problem in installing the purge button and face, you can see the incorrect installation by visual inspection due to its shape. Installing the diaphragm in reverse is not possible. Should the ring screw come off, the locking mechanism of the clear button will operate thus the diaphragm is designed not to fall off. Note that the diver can also sense abnormalities at the point where a few drops of sea water will enter the second stage (discharged during the exhaust strokes) by each inhalation.
In addition, DIVEWAYS has the ability to attach an emergency valve having patented which makes it possible to supply a quantity of air to the second stage in case of an emergency regardless of a diver’s ability to breath air from the main tank. The demand rubber valve holds down low pressure air from the first stage (which is designed to push open). DIVEWAYS emergency valve makes it possible to adjust the air supply from a very small amount to a large quantity by simply turning a knob which is a new and original concept worldwide. Therefore no matter what type of accident happens during the dive . from equipment freezes during ice dives to damage of the demand lever or an exhaust valve that has fallen off or a crack in the diaphragm . it is still possible for the diver to have enough air to ascend safely.
In addition to these items, other DIVEWAYS products are also designed and produced based on the FAIL SAFE concept. These include the exhaust (as pictured), dust cap, installation system of the low pressure hose, and the structure of the high and low pressure hose cover. For example, typically most of the exhaust systems feature plastic or stiff rubber attached to the second case by screw. There are a large number of divers who have had their second stage pulled from their mouth due to contact with coral, their own equipment, or other obstructions. This situation could potentially cause beginning divers to panic and forget their training. DIVEWAYS avoids this problem altogether by producing exhaust systems with very soft rubber of superior durability and quality. The patented fixed system requires no screw or tool and thus allows for very easy installation and removal. This makes checking the exhaust valve very easy to do.
One other example is the individual system
adopted for the low pressure hose piping,
Also, the string portion of the dust cap can sometimes be cut due to the over-tightening of the yoke knob. The DIVEWAYS dust cap has been designed to release the force built up from over-tightening, thus insuring that the dust cap will never be severed from the equipment. In addition, the size and shape of the yoke knob is designed to avoid more tightening than is actually needed. Other features include a drainage design that utilizes gravity to force the salt water out of the equipment during cleaning, preventing crystallization which leads to rust and other damage.
Because diving is a worldwide sport, our design parameters require that assembly and disassembly be as simple as possible in order to allow for unexpected circumstances in different environments. Neither the first nor the second stage requires any special or unique tools for assembly or dis-assembly other than your basic, typical tools found in most households. A simple screwdriver or a nail as a substitute of screwdriver is all you need to assemble or disassemble the second stage. As a result, divers using our products no longer need to be concerned with carry around tools except for consumable parts such as O-rings in anticipation of problems. Of course, the goal is to produce equipment that does not break down in the first place. However there is always the chance something can happen, and with that in mind while we design, we have done everything possible to ensure the safety even in the event of a breakdown. Again, safety all comes back to the FAIL SAFE design and we always try to consider “what ifs” as we design and produce our equipment. In summary, our thorough management and control of the design and management process by skilled technicians results in a FAIL SAFE system of safety that brings a sense of satisfaction and relief to our customers.
