1st Stage

RS-790 DIN

Dry Ambient Pressure Chamber Pneumatically Balanced System

The dry ambient pressure chamber on the R-700 prevents water contact with the diaphragm and spring maximizing performance, at any depth, in cold water conditions below 50° F / 10° C.

1st Stage

Ideal For Cold Water Environments

The cold water ready feature enables the regulator to be used in waters below 50°F / 10°C tested to a temperature of 39°F / 4°C.

2nd Stage 2nd Stage

The S-90 second stage is a pneumatically balanced design. A small chamber positioned at the end of the poppet assembly traps air and forces the poppet back against the intermediate pressure orifi ce. This provides decreased inhalation resistance and increases smooth breathing in all conditions.

Cold Water Ready

Cold water ready for water temperatures below 50°F / 10°C.

Ortho-Conscious Mouth Piece

Reduces bite tension in the jaw.

Venturi Flow Adjustment

Air assist on inhalation improves breathing resistance.

ORTHO-CONSCIOUSLY DESIGNED MOUTH PIECE

The new mouth piece, developed on the basis of ergonomic engineering, further enhances the comfort of bite, fi t, and stability. Even with a light bite, a high level of stability is achieved, so there is no fatigue from long periods of usage.

Proven to be durable and reliable, and ideal for rental.
