That is clearly an indirect drive compressor, and if it slows down the RPMs at the crankshaft for the pistons it can reduce sound a great deal. It may not produce much more air than a direct drive single cylinder compressor but driving a single cylinder at 3450RPM creates much more noise. The picture also shows individual mufflers on the intake ports where most of the noise is generated.
