1st stage DB4 NITROX

Combining the time-tested DS4 platform with MTX technology. The result is a compact, extremely durable regulator. A robust dry chamber closure with reinforced diaphragm helps prevent ice build-up while protecting the regulator from impact. A heat exchanger around the diaphragm increases the temperature of the breathing mixture inside the 1st stage. Classic shape is suitable for most configurations - single-bottle diving, twin-bottle diving, stage.

This regulator is assembled in special contamination controlled rooms (Clean Room class "J" (10000)).

Features

• membrane balanced
• dry chamber sealed - reinforced membrane integrated in impact resistant cover
• massive heat exchanger around the dry chamber and main membrane
• 4 x MP outlet 3/8" UNF
• 1 x HP outlet 7/16" UNF
• location of MP outlets: radial
• material: brass
• finish: satin chrome
• weight: 630 g
• DIN M26 300 bar
• oxygen clean
• EN250A

Stage 1 DB4+

This compact, extremely durable 1st stage is the result of combining the time-tested MTX technology. A robust dry chamber closure with a reinforced membrane helps prevent ice build-up while protecting the controller from shock. A heat exchanger around the diaphragm increases the temperature of the breathing mixture inside the 1st stage. Classic shape is suitable for most configurations - single-bottle diving, twin-bottle diving, stage.

DB4+ has two high pressure outlets.

Features

• membrane balanced
• dry chamber sealed - reinforced membrane integrated in shockproof cover
• massive heat exchanger around the dry chamber and main membrane
• 4 x MP outlet 3/8" UNF
• 2 x HP outlet 7/16" UNF
• location of MP outlets: radial
• material: brass

Stage 1 DS4 NITROX

The cornerstone of the breathing apparatus of many divers around the world. It finds use as part of recreational sets, double-mounts, stage cylinders and rebreathers.

The compact body has four medium pressure and one high pressure outlets. Isolation from the environment by a dry chamber (DS system) makes it suitable for cold water diving and contaminated environments.

Compact size, high reliability and excellent performance in all conditions are the reasons why the DS4 was selected by the UK Ministry of Defence in 2007 as the only regulator for military air diving operations and is integrated into all breathing apparatus used by the country's military divers.

This regulator is assembled in special contamination controlled rooms (Clean Room class "J" (10000)).

Features

• membrane balanced
• dry chamber sealed - DS system
• 4 x MP output 3/8" UNF
• 1 x HP outlet 7/16" UNF
• location of MP outlets: radial
• material: brass
• finish: polished chrome
• weight: 654 g
• EN250A
• oxygen clean
• DIN M26 300 bar

Stage 1 DST4 NITROX

The 1st stage DST4 has four medium pressure outlets located on a rotating head. This allows the attached hoses to be moved to ideal positions around the axis of the first stage. For special configurations (sidemount, double-mount), the number of medium pressure outlets can be extended by a fifth, axial outlet.

The DST4 is enclosed by a dry chamber (DS system). Isolation from the surrounding environment makes it suitable for cold water diving and contaminated environments.

This regulator is assembled in special contamination controlled rooms (Clean Room class "J" (10000)).

Features

• membrane balanced
• dry chamber sealed - DS system
• 4 x MP output 3/8" UNF
• option for a fifth, axial 3/8" MP outlet UNF
• 2 x HP output 7/16" UNF
• location of MP outputs: radial, swivel head
• material: brass
• Surface finish: chrome
• oxygen clean
• weight: 765 g
• DIN M26 300 bar
• EN250A
