External Din300 High Pressure Air Regulator by Huma-Air, to reduce the outgoing scuba tank pressure to a lower working pressure, for filling your rifle or tethered shooting.

This external high pressure air regulator is specially designed for airgun shooting or filling and it can be screwed on to a 200/300 bar scuba tank with DIN300 connection.
The regulator will reduce the outgoing pressure according to your settings, so you can optimize the working pressure matching your airrifle or pressure tube.
A stable pressure is the base for a a constant pelletspeed and better groups when you are shooting tethered. 
With the large bronze set screw you will be able to adjust the outgoing pressure very precize and the regulator is equipped with two pressure gauges, one shows the tank pressure and the other one will indicate the output pressure.
An 28 mm digital mini pressure gauge or a Wika analogue gauge can be placed on the regulator for the input- or output pressure as option.

One turn of the handwheel counter clockwise will raise pressure approximately 40 bar (580PSI)

A breedscrew is fitted to the regulator body so this regulator can fully function as a stand alone fillset.


The input pressure is 200/300 bar and the output pressure is stepless adjustable from about 50 up to 250 bar.
The regulator is fitted with a G1/8BSP male connection what connects to most fill hoses, or you can screw a foster male coupler on it.
