I am pretty sure the AntiGravity guys had one that went that high and it was a regular Sears brand garage compressor. I remember they broke it trying to hit 500PSI or something like that in their video.

I have seen that video before. I think it was a regular like 5 gallon garage compressor like you said but with the tank and pressure switch removed so it could just keep running until it broke.

That sounds awful risky. I bet the compressor part wouldn't explode if it were overloaded, but the tank surely would. I hope they bypassed that tank!

Yes they removed the tank from the compressor. Otherwise you would be standing by a bomb.

Hi,

The compressors in fridges will go to 30 bar (900 psi) or so. The biggest problem is finding a junked fridge where the compressor still works. A year or two ago, people would have their whole kitchen replaced if they didn't like the color, but now....

I never knew they went that high. I thought it would be only around 300PSI. I read that somewhere on another wrocket website. I threw out a working refrigerator not long ago too. It had been in my basement and got all rusty and nobody wanted it. I'll be kicking myself now!

mmmmm 30 bar is about half of 900psi, as far as my maths go , 900psi is about 62.052703 bar

1bar is 14.5038 psi

hope that clears things up,
but if a fridge compressor does go to 30 bar thats still 435.114 psi which is enough to blow your socks off
:D

Hi, yeah oops 30 bar is only about 30 * 15 = 450 psi. My bad.

That's still a lot more pressure than my best design can hold at this point. It might be worth investigating.
