The RS-340 regulator always supplies divers with stable air flow at any tank pressure or depth, delivering maximum breathing ease and comfort for any diver.
The R-300 first stage delivers an over- balanced diaphragm system featuring a minimum variation in intermediate pressure in relation to changes in residual tank pressure. The ports (H.P.x2, L.P.x4) feature left-right symmetry for easier tank adjustments, even for novice divers.
Universal swivel hose joint
For optimum performance and comfort, a swivel joint is fitted between the second stage of the RS-340 and the joint section of the low pressure hose. The swivel joint allows flexibility of the hose to eliminate hose tension at the mouthpiece for a more natural and comfortable bite. Ortho-consciously designed mouthpiece
The new mouthpiece, developed with engineering in mind, 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.
Breathing resistance adjustment knob
Respiration rate and air consumption rate vary greatly while diving according to environmental conditions (water depth, current, etc.) as well as the skill and physical condition of the diver. A necessary condition for safe and pleasant diving is natural breathing in correspondence to the circumstance at any given time. With the S-40 and S-30 you simply rotate the flow adjustment knob on the side with its ideal click feeling for free control of the air supply volume according to your needs. The multiple thread screws permit speedy and fine adjustment from which you can appropriately sense resistance to exhaled air, to a condition in which you feel almost no resistance.
