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.
