Description Apollo Bio-regulator A-320 Nrx Apollo Bio-regulator A-320 Nrx package of the 1st stage regulator that lavishly uses tough forging body and yoke, and the easy-to-use 2nd stage regulator that equips swivel joint. It supplies comfortable air even under all circumstances. Features for 1st stage: 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. Double Diaphragm system – bio-regulator has double diaphragm system for prevention from water leak and corrosion of the other parts. Also, the regulators keep their function in the cold water, because those diaphragms protect freezing the parts. 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. Features for 2nd stage: 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.
