Blowing out much of anything requires a fair amount of air. In my computer business, I keep a Senco PC1010 in my truck so I have something to blow things out. Small, light, quiet, but pretty frustrating if you need more than blowing air for 20 seconds or so. I keep a MAC700 in my maintenance are. Much heavier but that doesn't matter if its sitting still. Not really any louder since the frequency is much lower. Perhaps easier to work nearby. If I'm blowing out a couple servers, I'll haul the MAC700 to the customer as it will survive under near 100% duty cycle.
The MAC700 will also let you inflate high psi tires like a truck.
