The QuietCool CL-3100 is part of the classic series fans. These fans have given QuietCool the reputation of a high-quality manufacturer of extremely quiet fans. It features the same energy saver motor that has taken the home ventilation industry by storm. The QC 3100 is a very powerful classic series fan, yet it still only uses about 300w to move over 3190 CFM (cubic feet per minute) of air!

The CL-3100 can be used as part of a customized system. Install this powerful whole house fan in a central location in the home, and add smaller individual fans to take advantage of zoned cooling and maximum control of your quiet cool system.

Ask a Question
  • I have a 3-speed RC hub. Can I use it with the 2-speed QuietCool 3100?

    Thank you for your question.  I am not sure what make and model your hub is, but below is a link to the installation instructions for this unit.  On pages 8-9, you will see the wiring instructions that you can compare to your exsisting hub and determine if it will work.

  • what is the necessity of the 14"x22" damper ceiling box

    This box and grill portion is what is installed in the ceiling of the home, then the air being exhausted is moved to the attic, then out the attic vents.

  • for a 1585 sqft single story home what would be min/max cfm application

    Typically it is suggested to exchange the air in a home approx. once every 3 miunutes.  In this case, if your ceiling height is 8 ft. your cubic feet of space will be 12,680.  This QuietCool fan will exhchange the air approx. once every 4 minutes.

  • does the bundle timer and two speed switch fit on a two gang electrical box?

    Yes it would require a two gang box.
