FX Impact CF Bottle - What Do The Numbers Mean?

[MikeAllen]

My M3, purchased from Utah Airguns, like many/most, was delivered with 250BAR FX gauges.
The air bottle, made by INOCOM for FX, states:
PW250 PH375BAR @15ºC
PSMAX 315BAR @65ºC

What do all of these numbers mean, and can I fill my M3 to 300BAR if I replace my 250BAR gauges with 300BAR gauges or would I need a 300BAR CF bottle?

PW250 means working pressure, only fill to 250 bar
PH375 is the hydro test pressure
You will need a 300 bar bottle,but you don't get a lot more shots and more stress to components

PW = Pressure Working
PH = Pressure Hydro

Also, the higher the temperature, the lower the pressure rating.

PW = Pressure Working
PH = Pressure Hydro

Thank you!

Thank you! Question - I can see that there may be added stress up to and including the first regulator, but if it is set at 150 bar I wouldn't think there'd be any stress from there on....would you agree with that?

If the first reg doesn't fail you should be good

Thought so, many thanks!

I have a 300Bar bottle on my 2 reg Impact and fill to 270-280Bar. FX has stated many times you can use a 300Bar bottle fill on a 2 reg Impact/Wildcat/Maverick. Some people dont like the idea and choose not to, others fill up to the max. I like the extra shot count I get by filling higher on the little 300cc bottle on my stubby Impact. My single reg Impact has a 300Bar bottle on it too with a high pressure Huma reg, but I would never fill past 240-250Bar.
