Any ideas or suggestions on how I could control a 5A 110vac Fans/Blower speed using a 0-10vdc signal?

RE: Using 0-10v to control an AC Fan
Shaded pole motors, such as ceiling fans, can be controlled with variable voltage only, i.e. rheostat. Analog input means needing to use an electronic voltage controller such as is used on heating elements. Try Watlow or people like that. The Bardac drive will work here too, just more expensive.

Let me add that you are describing a 3/4hp motor. You could also use a (less expensive?)(more reliable) 3phase motor with a more conventional 3phase VFD running on only a single phase source. Most would accept a 0-10V input directly.
