“Keep it Simple!” was the leading mission statement while engineering the SF2. The vision became mission and finally reality. This is evident at first sight: The SF2 is configured very cleanly and simply. Compared to other rebreathers, the SF2 is compact and well-arranged. The reason: All important components are integrated into the carbon fiber tube. Therefore, the SF2 needs significantly less volume compared to other rebreathers. Tests, as well as various certifications, assure a constant level of security while diving. The SF2 is especially suitable for ambitious technical dives. It is available as either a backmount or sidemount rebreather.
As if it were designed from one piece, the SF2 is shaped cleanly and simply. Moreover, the carbon fiber tube gives the SF2 a new, streamlined and high-quality design
The assembly and disassembly of the SF2 is very simple as the entire tube can be removed and all the internal parts easily reached.
The electronic chamber is located within the head. The adapters of the breathing hoses are mounted at a slight angle on the head. This leads to a perfect positioning of the unit, as well as being, increadibly comfortable. The scrubber canister is located between the head and midsection. Concerning the midsection, two different requirements of modern rebreathers are combined. First, you can find the bypass (ADV) which provides gas in case of low volume in the system. Second, the adapters of the “Manual Add” are located here.
The SF2 is a fully electronic closed-circuit rebreather engineered in Germany for divers all over the world.
Electronic Chamber The electronic chamber is the heart of the SF2. The O2 sensors as well as the Oxygen solenoid and the battery compartment are located here. The O2 sensors are located in a separate chamber to protect them from moisture. The electronic plate is located below the battery compartment. High-quality SMB angle plugs connect the plate with the sensors.
Unique positioning of Counter Lung Compared to other rebreathers, the SF2 differs in the unique positioning of the counter lung. Often, the counter lung is positioned on the chest. In contrast, the SF2’s counter lung is located in the lower tube. This leads to an ideal diver’s position in the water and low resistance.
Manual Adds & Off Board Gas Connector The “Manual Adds” are made of Delrin and enable you to add both oxygen and diluent manually. The “Off Board Gas Connector” - a high-quality Swagelok quick connector - allows you to add external gas. Hence, the fundamental idea of redundancy while diving is completely secured. Constructionconditioned the entire periphery works while applying “Off Board Gas”.
