R8 BALANCED DIAPHRAGM 1ST STAGE

▪ High-flow, fast-acting valve system capable of delivering a large amount of breathing gas in an
instant, irrespective of breathing demand, cylinder pressure or depth. It has not only passed the
stringent CE test but the performance is comparable with the best available
▪ Four intermediate pressure ports (located in the swivel turret) and two high pressure ports
▪ Available with YOKE or 300 bar DIN (G5/8) connector
▪ Anti-freeze models are available separately. Intermediate pressure setting: 9.5-10.0 bar (137-145 psi)
▪ Ventilation rate: 206 bar (3000 psi); 3820 L/min (135 cu ft/min)

Ventilation rate at 3000psi (206 bar): 135 cu ft per minute (3820L)

Regulator
With full CE certification and performance that is on par with the finest regulators on the market, the R860 is
well-suited for stringent cold water, deep dives and demanding profiles. It can also be fine-tuned for smooth,
responsive gas delivery in more relaxed conditions.
The R860 is the flagship in IST Sports’ Pro Line of scuba regulators, and rightfully so. Its R-8 1st stage is a balanced diaphragm design that’s available with an optional environmental kit that prevents freezing when diving
in cold-water conditions. There are two high-pressure ports and four intermediate ports mounted on a swivel
turret for easy hose routing. On breathing machine simulator tests, the 1st stage is one of the best ever tested
by Scuba Diving Magazine’s ScubaLab. The O-60 2nd stage is equipped with a metal balancing tube and a pair
of user adjustments: the dive/pre-dive thumb lever detunes the regulator to minimize freeflow on the surface;
the breathing resistance knob lets you regulate air flow as you descend to deeper depths. Bottom line: the
R-860 is designed for divers of all skill levels and for water conditions ranging from tropics to the arctic.
