External Din300 High Pressure Air Regulator

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 sold separately.

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

A bleedscrew 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.
A microbore fill hose (not included) can be found in the Air Charging and Fittings section.

Huma-Air Quality Control  

Huma Air regulators are CNC produced out of high grade aircraft aluminium and bronze. To guarantee a perfect product, every regulator is individually assembled, tested in a computerized simulation program and adjusted to the requested pressure. 
We only use high-end materials and our Belleville springs are designed for critical applications to achieve the highest repeat accuracy. This gives our regulators a repeat cycle with less than 1% difference.
