The RS-670 is TUSA's latest regulator that delivers superior performance and quality in a compact lightweight travel-friendly system. Improving upon the success of the R-500 series released in 2008, the R-600 mated with a newly developed S-70 second stage further pushes the engineering and performance envelope. The newly designled ultra-compact balanced diaphragm R-600 first stage is incredibly small and weighs only 630g. The R-600 is configured with 2 HP and 4 LP ports allowing for versatile hose placement. The R-600 is also available in a DIN version.
