Don't have either; I take it an air compressor is like a vacuum cleaner? By some miracle it is now up and running. New Year's resolution number 1: keep all beverages away from keyboard. Thanks, Carolyn. Happy New Year!
No, not like a vacumn, it's a thing that you keep in the garage and when you turn it on you get really strong air to blow things out and off.. (through a hose). I love it when I'm cleaning house to blow off plants, and blow dust off the duster, but it's good to clean out things like a dirty keyboard from time-to-time.
