Top performing pneumatic regulator.

1st Stage

Dry Ambient Pressure Chamber

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.

2nd Stage

Advanced Flow System

Grants smoother air delivery due to the curved housing structure.

Cold Water Ready

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

Environmentally Sealed 1st Stage

First stage is sealed against contaminants and freezing water.

Ortho-Conscious Mouth Piece

Reduces bite tension in the jaw.

Pneumatically Balanced 2nd Stage

Provides optimal breathing resistance at any depth.

Venturi Flow Adjustment

Air assist on inhalation improves breathing resistance.

Pneumatically Balanced System

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 orifice. This provides decreased inhalation resistance and increases smooth breathing in all conditions.

Stage

Cold Water Ready

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

Ortho-Conscious Mouth Piece

Venturi Flow Adjustment Reduces bite tension in the jaw.

Air assist on inhalation improves breathing resistance.

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

ORTHO-CONSCIOUSLY DESIGNED MOUTH PIECE

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