Dc blower that I looked at requires 9amps which might kill a psu over time. The 110 volt I could wire up along with my pump with ease.

Dimmers are inductor based. A circuit that could change the frequency of a sizable AC current would most likely cost more then whatever you were trying to use it with. Its a lot more complicated then simply reduceing the current so that the motor isn't as effcient.
