Funny, I have seen the same compressor on your PFT page with the words 'just not good enough' I think was right.
With regards to getting all sarcastic about special green air etc.
They are calibrated and so is the machine to suit each other. You couldn't just buy any old air comp and plug and play to allow the machine to perform to its optimum level
The wrong one, the wrong calibration will cause the customer an issue. We sell the machines, make the air compressors also and know what we are talking about.
