G28 Clarification - Air Powered Shooter

My team is discussing strategies for shooting fuel at a high rate. A google search for "Wiffle ball shooter" produces some videos of leaf-blower powered shooter, and we thought this would be a good solution (powered by a legal motor/in a legal fashion) However, there are a couple sticking points. The first, G28:

A strict reading of the rule would say that this strategy is illegal if the flowing air affects our launched fuel after it leaves the robot volume, as fast-moving air may tend to do. A less strict interpretation (possibly the intention) is that this rule would only affect FUEL units that are either uncontrolled or controlled by the opposing alliance.

The second sticking point is whether using air in this fashion is legal at all. A cursory search of the rules does not explicitly disallow this (as in whether a fan is a pneumatic device )

Thanks for your input. Please let me know if I missed anything in the rules that pertains to this question. We also intend to ask Q&A for clarification/intent when it opens.
