SF2 ECCR REBREATHER

"Keep it simple!"

Was the leading mission statement while engineering the SF2.

 

Keep It Simple!

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.

Streamlined Design

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.

Easily

Built The assembly and disassembly of the SF2 is very simple as the entire tube can be removed and all the internal parts easily reached.

Compact Installation

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. Construction-conditioned the entire periphery works while applying “Off Board Gas”.

SF2 ECCR SIDEMOUNT REBREATHER

SF2 ECCR Sidemount

The SF2 ECCR is certainly the most popular Sidemount rebreather in the world. Its compact size, combined with a low weight and a robust structure make the SF2 Sidemount a popular and reliable companion on exploration dives around the globe. The basic components are taken from the SF2 Backmount version. The SF2 Sidemount has the same compact electronics chamber and inner bellows counterlung. The upper and lower tube are constructed of a very light, yet durable carbon fiber.

For the ideal use as a Sidemount rebreather the following adaptations were devised.

Side Mount Loop

The SF2 Sidemount rebreather has a DSV / mouthpiece especially designed for the sidemount application. In collaboration with the best Sidemount divers in the world, we have developed a unique mouthpiece with excellent features:

  • Optimum hose feed
  • Rotatable
  • Right / left hand use
  • Integrated chin rest
  • In water neutrally buoyant

Side Mount Frame

To keep the SF2 Sidemount rebreather as slim as possible, it has a special frame. This frame is made of stainless steel and fits very closely to the carbon tubes. Thus, there are no protruding parts.

Attachment

To configure the SF2 Sidemount rebreather as close as possible to the body, it has three attachment points. We’ve designed a stainless steel rail at the top of the head and included two large Boltsnaps in the central region held via a hose clamp to allow for a streamlined attachment to your existing harness. The Boltsnaps can be varied in length, so that the rebreather can be positioned individually.

Manual Adds & Offboard Gas

To successfully accomplish this, the idea of ​​“streamlined” configuration was ingeniously devised. The manual O2 feed has been built directly into the body of the rebreather. Thus, the diver can inject oxygen into the SF2 rebreather via a simple push button. The external (DIL) gas supply is provided by male and female Swagelok connectors whereby a reliable gas supply is ensured and cannot be confused.
