SF-2 Rebreather Sidemount

SF-2 Rebreather Sidemount


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


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.


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.
