Regulator 1st stage DB4

1st stage DB4

Combining the time-proven DS4 with MTX technology. The result is a compact, extremely durable 1st stage DB4. The robust dry-chamber seal with reinforced diaphragm helps prevent ice build up while protecting the controller from knocks. A heat exchanger around the membrane increases the temperature of the respiratory mixture inside the 1st stage. The classic shape is suitable for most configurations - single, twin, stage.
