The RS-340 regulator is equipped with a swivel joint between the second stage and L.P. hose to minimize the pulling feeling. To insure natural breathing, a dynamic flow hose with a large inner diameter increases the airflow. The RS-340 always supplies the diver with stable air at any tank pressure or depth, delivering maximum breathing ease and comfort.
First stage (R-300)
The balanced diaphragm system features minimum variation in intermediate pressure in relation to changes in residual tank pressure. The ports feature left-right symmetry for easier tank adjustments, even for beginners.
Second stage (S-40)
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 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.
