The RS-130 combines the basic functions of the RS-110 with a breathing resistance adjustment function. If features glass fiber material in the second stage for superior shock resistance as well as a lighter weight and compactness. There's been a major reduction in friction resistance of moving sections and air resistance in the housing for smooth, ideal respiration.

The very popular balanced piston type first stage offers superior reliability for stable air supply regardless of depth or residual pressure. Maintenance is also a cinch. The first stage offers an extremely high limit value even for maximum operation values. There are two H.P. ports and four L.P. ports. The RS-130 first stage features a unique patented inline layout to achieve a light weight of just 620 grams during actual use, not to mention its compact size.
