Used it now for a month. It runs pretty quite. It pressurize to 116 psi (8 BAR) but will bleed out and hold at 105 psi (7 BAR) psi. I had to add teflon tape to the pressure sensor on the side of the compressor. Note: I replaced the ball valve on the compressor with a filtered regulator. I found out the threads are not NPT. I had to buy NPT to BSPT adapter fittings. The threads on the compressor pressure switch 4-Way stem is threaded 1/4\" BSPT. British Standard Pipe Taper is common in Europe (55 deg thread, 19TPI). The US uses NPT (60 deg thread, 18 TPI).
