Easy question!

[h90]

Recently I was on a dive boat with an old bauer compressor.
I liked to look it (and was surprise that the belt and the wheels are running open without protection while children are arround (snorkelers) and the boat is shaking with the waves.....
So I come into speaking with the Instructor who filled the tanks and he told me proudly that the first stage is doing 100 bar, the second makes it 180 and after the third it is 200-220.
I told him that sounds strange to me but he told he is 100 % sure (and a bit angry that I have doubts).
Still having doubts I found an older book telling as example: First stage 6 bar, second 45, third 200.
That sounds a lot more possible.
Can anyone put a light on that?
Thanks
Michael

He's a lost ball in tall grass, the book is right.

6/45/225 bar are the figures Bauer usually gives.

I think all compressor must have some simillar figures
as:
first 1:6
sec: 1:7.5
third: 1:5

On his design:
1:100
1:1.8
1:1.22

I don't think a 1:100 is technical possible, in my opinion no brand of compressor can do such a way or?

It's been a long time since I heard that one. Thanks for that one.
