The IST Sports R-2000 regulator combines a sealed, balanced first stage with a pneumatically balanced second stage to deliver smooth, consistent breathing at depth. Its sealed design, paired with an integrated heat sink, helps maintain reliable performance in both cold and contaminated water conditions.

Compatible with EAN40 nitrox mixes out of the box, the R-2000 offers versatility for a wide range of diving applications. The first stage includes two high-pressure ports and four low-pressure ports, providing flexible hose routing options.

The second stage features both a Venturi control and an adjustable breathing knob, allowing divers to fine-tune airflow performance based on their preferences and diving conditions.
