Product review (2 stars): These 2 together work well and I love it
Although it can have the external blower attach to it, the hole on the hood is small to take up the air /smell of food cooking. So we did not install it ,insted returned it and bought Broan elite hood which has a 10" diameter opening /hole and installed it .This works well with the Broan external blower Broan 336 with 1500 cfm .These 2  together work well and I love it
