It's a typical compressor with 1,5kW power and rotational speed of 2840rpm. The ratio is ½ therefore the shaft of the pump has 1500rpm, which allows the use of tools like a painting gun.
The pump is from a Star car, the cylinder from the trailer braking system.
The compressor switches down beyond 6,5 bar and switches on over 5 bar. The safety valve switches beyond 8 bar of pressure.
