Nitrogen Regulator 1 Stage 2 Gauge 3.5 Bar (AE3003LX)

The design of this regulator ensures that pressure is reduced from cylinder pressure (300 Max Bar Argon / Oxygen, 20 Bar Acetylene) and can be set to a suitable working pressure. These actions take place in a single chamber, making this particular model ideal for use where precise pressure settings over a period of time are not essential.

This product features two gauges, which display bottle contents and output pressure. Output pressure is controlled by the centre dial (pressure adjustment knob) which, when fully wound out, sets the pressure to 0 bar.

This model is of bottom-entry design, making it best suited to top-outlet valve cylinders. They can be used with side-outlet valve cylinders with the addition of a 90° adaptor (DA90LH/RH).
