Ducting a humidifier into the living space, will the Model 350 Aprilaire Humdifier work?

Consumer question submitted to Aprilaire:

Can Air Humidifier Model 350 be connected by ducting to living space? What 
standard size ducting can be used? Does model have an integrated 
blower? If not, please recommend a blower or air handler.


Aprilaires' response:

Yes, the model 350 humidifier is ducted into the living space.  Typically, this unit is mounted in the basement, on the ceiling, in the rafters of the basement.  It has an internal fan that draws in the air to be humidified, then expels the air into the duct that sends the humidified air into the living space.  Usually this is on the main floor level, through a wall. 

The ducting comes out of the humidifier, goes up into the ceiling of the basement, (floor of the main floor) and goes into a wall.  It will then vent out of the wall, at floor level, on the main floor, in the living space.

The duct from the humidifier that exhausts the humidified air is seven inches.
