I suppose anything is possible, but would require me to have three bad gauges that are all in agreement. The statement earlier about the compressor being a 300 bar compressor as stated by the manufacturer, is that 300 bar is just over 4300 psi, not 4500. Their ad is misleading as it says 300 bar, then they say 4500 psi. IF 4500 is working for many of you, glad to hear it, I just know on mine it blows the burst disc if I go that high, have had others report the same. I'm not trying to pick a fight, just don't want to see others having problems and become aggravated with their compressor.
