Hi Barbara: Brian and Gregg are correct. That compressor motor has the  
same direct drive design as my %*&$ing LOUD compressor. I hate that  
thing. I wish it would die so I can get a "real" compressor. You want  
the piston-type compressor with the belt between the motor and the  
compressor piston(s). Gregg was correct that you need to looks at the  
specs for your tool that the compressor will be driving. If the tool  
will be running for a good while (more than short bursts), the  
compressor needs to output at least the same CFMs at the rated  
pressure that the tool consumes, or the tool will forever run slow. My  
compressor is adequate for most of my needs, but when I run my air- 
powered sander, it only runs at full speed for a couple minutes, then  
after the air tank pressure runs down, the compressor can't deliver  
enough air volume and the sander goes along at half speed - it still  
works, but is much slower......  :-(
