Luckily for me my step-father owns one of those compressed air machines
I have one too that I use for computers and other electronics. However, because there is no way to prevent moisture from condensing inside the tank and mixing with oils and other debris, NEVER
use an air compressor on electronics unless it is equipped with a suitable moisture and particulate filter such as one of these
. Otherwise, you risk spewing rusty, oily contaminated water on your sensitive electronics. Not good! Also, use a Popsicle stick or something similar to hold the fans stationary while blasting. The compress air can easily spin a fan faster than designed limits, damaging the bearings. And of course, take the computer outside to blast clean.
