I'm not sure where you're getting your air duster but none of the stuff I've seen is R-410a. It's usually R-134a or R-152a. R-410a would be a much higher pressure. Trying to run an R-410a system on either of those refrigerants would not work out well.

Also even if they are full of whatever refrigerant you need, they aren't even close to pure enough to use in an AC system. I'm also not sure how you'd get it out of the can and into the system. You would need to make some sort of custom piercing tap or adapter for the can.
