Fan starts racing

If it's oil & moisture free, sure. I've came across compressors that had moisture build up in the tank. And I'd get a mist when I use it.
 
Ok, I ask because of that thread plus I was googling "canned air" & the images were too varied so I was wondering if a specific brand is best?
 
Ok, I just got a can of canned air & will be blowing out the dust bunnies soon. ANY particular areas tp focus on other than the fans?
