The Tusa RS-350 Regulator is the flagship model when it comes to Tusa innovation. This regulator has features not previously offered on any other model. There are two types high-tech filters 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. This also provides peace of mind, even when using less than perfectly cleaned rental tanks. Also, in order to achieve natural breathing, a dynamic flow hose with a large inner diameter increases the air flow. 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.

The first stage is a completely new design for Tusa. The balanced diaphragm system features minimum variation in intermediate pressure, regardless of tank pressure. The ports feature left-right symmetry for easier tank adjustments, even for beginner divers.
