Oh, I don't think so.

does any of you work for compressor manufacturer before?

YES, some of us have worked for compressor manufacturers. You might want to try to be a little more subtle in your posts. I can think of just several guys here who total over 100 years worth of experience. If I looked for more, it is there.

any other thing you wish to know?

Sure, how much experience do you have?
