AF, back sometime in the 1990's it was demonstrated to me how much static electricity is generated from an air blow gun. Chances of frying something in your dash might be slim to none, but I would not risk it to remove dust. Thousands of volts can be generated. There are ESD air guns to eliminate the voltage chance, but why risk it?
I never thought of this before .... is there a risk if the car is off and no power is going through the car ?
