The IST R-2000 regulator combines the R-200 first stage and O-300 second stage

The first stage uses an environmentally sealed diaphragm design to help prevent water, silt, and contaminants from entering the mechanism. This supports reliable operation in cold or low-visibility environments, where protecting internal components is important.

The first stage features multiple high- and low-pressure ports, permitting flexible hose routing for various configurations, including octopus and instrumentation setups. Its compact construction supports both travel use and standard recreational configurations.

The second stage is air-balanced, delivering stable airflow regardless of tank pressure or depth. A diver-adjustable inhalation control allows tuning of breathing resistance, while a venturi lever helps control airflow and reduce the risk of freeflow at the surface. The housing is designed to be lightweight while maintaining durability for repeated use.

The regulator is compatible with nitrox mixes up to 40 percent without modification, which makes it suitable for a wide range of recreational diving applications. Standard hose connections and fittings provide compatibility with common accessories and alternate air sources.

The R-2000 set is aimed at divers looking for a dependable, straightforward regulator system that combines environmental sealing, adjustable breathing characteristics and flexible configuration options free of unnecessary complexity.
