TUSA RS-1001 Regulator

The compact and lightweight TUSA RS-1001 Regulator is made up the balanced diaphragm R-1000 first stage and the S-0001 second stage. These two stages work together to create a well built and durable regulator.

The R-1000 first stage comes with a cold water insulation system and has four low-pressure and two high-pressure ports. The first stage is fined tuned for performance with the high flow low-pressure ports offer up to 15% increased air flow. This first stage is effective and efficient, designed to offer tuned performance for as long as you need it.A DIN version is also available that offers 300 bar(4350 psi).

The S-0001 second stage comes in a lightweight and compact case and the clever venturi air system. This system allows the user to control the direction of airflow through the mouthpiece to make sure that breathing is as easy as possible. It also comes with a ortho-consciously designed mouthpiece to stop fatigue when using the regulator. This makes it easier on you to use and means you can use it for longer without putting strain on the jaw.
