I recently purchased two 6 Duct Booster Fan from Northlineexpress. I installed them in my fireplace heatilaters with much success. They work very well and the amount of air pushed is considerably greater than the original factory installed fans. We are very pleased.
Looks like it will do the job, will find out this winter.

This fan works very well. I have a Pellet stove in our cellar and I am using the fan to move air through the floor grates. I have the fans plug into remote controlled outlets so I can control the heat room by room.
