This may sound like a silly question, but what kind of blower did you get?
One thing to look out for, just a suggestion is make sure the motor for the fan doesn't spark too much. I'm sure it's just fine, but if it does spark, you may have a fire hazzard. Now as I said, it's a small thing, but something to think about. What could happen is if the blower does spark a little it could ignite the paint fumes.
