depends on how much air we're talking about. Ive got a 160psi air compressor in my garage and using the blow gun can cool two freshly welded (with a Mig) pieces of 1/8" steel from a few thousand degrees celcius to cool to the touch in seconds. I can't imagine how noisy air jets would be. Would make Delta or San Ace fans seem quiet.
