Can an in-line fan be added to my Aprilaire humidifier?

Consumer question:
Can I add an in-line fan to the humidifier bypass duct in order to increase the humidity?
Aprilaires' response:

Thank you for contacting us with regards to our model 400 Humidifier. This humidifier requires between 60-100 CFM to operate properly. If the air provided to the humidifier is lower than 60 CFM, an in-line fan may help increase the humidification rate, but it should only run with the furnace. As a drainless model, it does not humidify well without a source of heat to evaporate the water.
