Regulator in Airmax

[Nordic Norm]

Hi folks, new here to this forum. I'm putting a Huma regulator into my Hatsan Airmax .22cal. The gun is setup from the factory with no regulator for a maximum 200bar fill, the gun bottle is rated at 300bar. With a regulator installed is there any reason the tank can't be filled to 300bar?

I don’t think you should exceed the design specs for the gun. Should the reg ever fail, the gun will see whatever your fill pressure is…maybe fine, but I wouldn’t risk it.

Hatsan said the limiting factor is the air tube which is rated for 200bar.

Hmmm, that’s a tough one. Will they tell you the working pressure for the rest of the gun?

The bottle is rated for 300bar. The rest of the rifle is downstream of the regulator so the limiter is the air tube. Bet 250bar is ok

If you can set up a regulator similar to the gauntlet, if it has a blowout disc on the bottle end at 300 bar and one on gun side at 200 bar, seems it would be safe then. The gauntlet protects the rifle side with a blowout disc. If the regulator fails high, or leaks while bottle pressure is higher than is safe for the receiver, the disc pops.
