This External PCP Regulator built by Huma is specially designed for airgun shooting is can be screwed on to a 200/300 bar scuba tank with DIN connection.
The regulator will reduce the outgoing pressure according to your settings so you can optimize the working pressure matching your air rifle. This will result in a constant pellet speed and better groups. The regulator is equipped with a pressure gauge what will indicate the set pressure. The pressure can be set by turning the set-screw to adjust the pressure. Just unscrew the regulator from the tank, adjust it it to your wishes, and screw it back on.

The outgoing pressure range can be stepless set from 70-250 bar within the three spring setup's
1: 70-125 bar
2: 100-200 bar
3: 180-250 bar
Within these settings the regulator can be set stepless in pressure. The standard setting is “2” in the pressure range 100-200 bar.
Because of the de-pressurize screw and manometer the regulator can also be used as a stand alone fillset. You will need a fill hose with 300 bar DIN connection to attach to the regulator (not included)
If you already have a fillset with 300 bar din connection it can be screwed into the regulator.

Please read the manual carefully before operating the External adjustable inline regulator
