Good point, but the release mechanism isn't a solenoid and would have to be exempt form the Cv limitation. Maybe low pressure systems (< 5 PSI) won't be considered "compressed air" rather "high energy fan system".

I'm also thinking of charging the cannon directly by the blower (no reservoir) and just tuning the blower ON/OFF. Modulation of the force would be done by varying the voltage on the blower motor.

At any rate, I'll be protoyping this today and let you know if the performance makes it worth pursuing.
