2/ Which gases can be used with the BHN3-2?

• It’s compatible with oxygen (O₂), nitrogen (N₂), argon (Ar) and clean air.

3/ How does the two-stage pressure regulation work?

• The first stage reduces high inlet pressure roughly to an intermediate level, and the second stage fine-tunes the outlet pressure. This dual-stage design maintains a stable outlet even if the primary pressure fluctuates significantly.

5/ What material is the body made from?

• The body is constructed from SRS-HS brass, offering high corrosion resistance and durability.

6/ What connection ports does it have?

• Inlet: W22×1/14 right-hand cap nut (14 mountains)

• Outlet: Rc 1/4 threaded valve

7/ How should I install and calibrate the regulator?

• Mount it immediately downstream of a particulate filter and moisture trap to ensure clean gas.

• Tighten all fittings, check for leaks, then adjust the outlet pressure via the fine-tuning knob while observing the outlet gauge.
