Once plugged in, you'll notice a small circle light up on the center surface of the machine. The compressor intensity is adjustable via tactile-touch on this lit center circle. The first tap turns on the machine to the lowest (recommended) air pressure setting, and the 2nd and 3rd taps will cycle through the medium and high pressure settings. The 4th tap will turn the machine off.

The compressor has 3-speed levels with the following PSI settings: 
Low speed - 20 PSI 
Medium - 25 PSI 
High - 30 PSI 

As mentioned above, we recommend the lowest pressure setting for your Aeroblending needs.
