Re: Dangerous
I agree, but as with all compressed air jobs, use with care.
A good mantra is "You know electricity can be dangerous, right? Compressed air more so."
I do use workshop air for cleaning appropriate electronic equipment, carefully.
I've always been cautious, especially with fans. Just what kind of an emf / spike can be generated by a fan being spun at a gazillion rpm? There's bound to be some residual magnetism in there somewhere, even for an induction motor. And, if there's no moisture in the air, What about static?
Anyway, I want the dust OUT not compressed into a corner somewhere.
