The RS-520 is the new flagship model when it comes to TUSA regulators, possessing a wide variety of functions. For example, there are two types of high tech filter built into the second stage, the first such system in the world. An active carbon filter cleans the air and absorbs smells, 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-520 always supplies the diver with clean and stable air at any tank pressure or depth, delivering maximum breathing ease and comfort for the diver.
