The RS-350 is the flagship model when it comes to TUSA regulators, possessing a wide variety of functions. There are two types of high tech filters built into the second stage, the first such system in the world. An active carbon filter cleans the air and absorbs odor, while a metal fiber filter eliminates particles as small as 100 microns. This ensures that the cleanest and safest air is supplied to the diver, so the diver has peace of mind even if the air in the tank should be become dirty. Also, in order to achieve natural breathing, a dynamic flow hose with a large inner diameter increases the airflow. Thus the RS-350 always supplies the diver with clean and stable air at any tank pressure or depth, delivering maximum breathing ease and comfort for the diver.

• Balanced diaphragm first stage
• Two H.P. ports and four L.P. ports

• Dynamic airflow hose
• Universal swivel hose joint
• Ortho-consciously designed mouthpiece

Features of RS-350
Balanced diaphragm type 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 (H.P. x 2, L.P. x 4) for easier tank adjustments, even for beginners.

Second Stage

Air Refresher
An active carbon filter absorbs odors, while a metal fiber filter eliminates particles as small as 100 microns, ensuring the diver breathes the cleanest and purest air.

A dynamic airflow hose with a large inner diameter increases air flow to the second stage.

Universal swivel hose joint
For optimum performance and comfort, a swivel joint is fitted between the second stage of the RS-350 and the joint section.

Ortho-consciously designed mouthpiece
The new mouthpiece, developed with ergonomic 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.
