There are several manufacturers of whole house fans. Some are small companies and other are huge. There are also some in-between companies. The actual fans are not really complicated. They consist of a housing to support an electrical motor and the fan blades. The better fans have better electric motors and better balanced blades. As you might expect, these fans cost a little more.
I have listed some average sized fans and their capacities below. The fans I have listed that are made by the Broan company are considered high velocity fans since they push more than 3,000 cubic feet of air per minute (CFM). I have also listed a low velocity fan after the following table that has two separate sets of blades. This one is made by Tamarack Technologies.

The Tamarack Technologies fan is the
HV1000. It has a neat special insulated cover that closes over the fan blades when the fan is off. This feature eliminates cold drafts in the winter or hot air from entering the house if you are using air conditioning.
