You are looking at the most silent quiet 20 CFM displacement Air Compressor 
 
This is a 7.5hp compressor slowed down to a 5hp to run silent and last longer than your ordinary piston air compressor
 
Because we are only spinning this pump at 650 RPM the noise is reduced the heat generated is reduced
 
The pump will last longer
Less moisture (dryer air) and water is generated due to the lower heat generated.
 
This is how Compressors used to be made years ago
