You're over-thinking this. There exist battery powered blower fans for specifically this purpose. I bought one on Amazon about a month ago. If you're blowing away SMD-soldered components with any kind of compressed air, either quit buying cheap no-name electronics or avoid using an aviation jet engine for your compressed air source. Edit : for the price of like 4 cans of compressed air cans, too. Just don't bother with anything else, get a battery-operated fan and move onto more important things in your life.
