IST Anti-Freeze Diaphragm 1st Stage with Second Stage Nitrox Compatible

R510 is IST new regulator sets based on tried and trusted diaphragm design. Coupled with tester approved O10 / O20 balanced second stage, the air flow characteristic is smooth and outstanding.

R-5 First stage features:
  • Tried and trusted balanced diaphragm design, giving exceptional performance even under the harshest conditions.
  • The intermediate pressure drop is kept to a minimum even with heavy flow demand.
  • 2 fixed high pressure ports and 4 low pressure ports on swivel turret for better hose configuration

  • R-5/N with All Consition kit:
  • All Condition environmental seal (on R-510/N) protects the first stage main spring from slit, harmful contaminant and especially the extreme cold.
  • Air is the medium used in All Condition environmental seal as it is the best insulator; the sensitivity of the regulator, however, is not affected with IST's direct pressure actuation design.

  • O-10 Second stage features:
  • Pneumatically balanced delivery system means significantly reduced breathing resistance comparing to conventional design
  • Dynamic diver adjustable flow button (on R-510 / R-510/N models) allows for quick tuning according to breathing demand
  • The vane near mouthpiece can help directing air flow towards the diver for effortless breathing or to be tuned into a gas conserving position
  • Exhaust cover with curvature directing bubbles away from field of vision
  • Light purging action
  • Equipped with NEW energy-saving hypoallergenic silicone mouthpiece with long tabs spreading the biting force more evenly!
