Description
1st stage
Reliably supply of comfortable air
Forged brass body
The body and yoke part adopt the basic member of forging.
The highly durable and less variation forged parts are further processed with cutting work.
- The oxygen compatible Viton O-ring is employed in the high pressure region to support Nitrox as standard.
- The 1st stage is EN250 CE certified, and it being used even with rebreather for pure oxygen application.
 Double diaphragm system
The adoption of dual double diaphragm system relieves a worry of freezing moving parts under low-temperature environments.
High performance H.P sheet
The heart of the 1st stage regulator is the newly developed tough and high-performance H.P. sheet bio 360.  It stably supplies the air over the long duration which far surpass current conventional reference of “3 million times breath” and “about 3000 dive”.
Bucket type dust filter
It adopts a bucket type dust filter. The dust filter in the high pressure region is high-density, thus susceptible to resistance.
By adoption of the special mesh filter made of stainless, the flow restriction and pressure loss of this part has been minimized by the large filter area, five times larger than the traditional filter.
2nd stage
Natural and comfortable breathing in the water
Bio air system
“bio-air system“, special structure inside of the 2nd stage, leads a direct air flow to the mouth.
It will release the valve by sensing slight pressure change in order to achieve a comfortable breathing without any discomfort being affected by changes in depth or pressure remained in the tank. The mouthpiece-tube, relatively small in diameter, reduces the fatigue of the jaw in diving spanning a long period of time.
Swivel joint L.P. hose
Well-established a swivel joint L.P. hose is equipped as standard, which reduces the fatigue of the jaw.
Water-repellent plated containing
Main metal parts are water-repellent plated containing fluorine resin, which reduces the operation failure due to the deposition of salt.
