Air duct booster fans
Here is a little fan called the "Air Booster" by Field Controls that is already installed inside a duct. You just cut into a ventilation or heating duct and replace a little section with this little fan and you can get a boost to the air flow. In-line fans can do the same thing with more power, usually triggered by a pressure sensing switch which reacts to air movement in the duct.
