Nitrox Ready and suitable for use with air or argon, the DGX First Regulator has a depth compensating flow through piston first stage with an intermediate pressure of 120 psi and includes an over pressurization relief valve.

Primarily intended for use in inflation and light SCUBA applications such as oxygen decompression, this first stage provides unusually good performance for such an inexpensive system.

Measuring {4.0 in x 1.5 in | 10.2 cm x 3.8 cm}, the regulator offers three standard size low pressure 3/8-inch ports (one is used by the OPV), one standard size high pressure 7/16-inch port, and comes standard with a 200-BAR DIN connector.
