QuietCool QC CL-4700 Classic

The largest single duct classic QuietCool is the QC4700 two-speed fan. This fan requires hard wiring to a switch for the two-speed option. It is perfect for homes up to 2400 square feet. When you purchase this fan, you will receive everything that you need for installation; the fan, ducting, damper and grill.  Just cut a rough opening in a central location just under the attic, hang the fan from a rafter and connect the grill and fan with the provided ducting.  Turn on the fan in the evening when the temperature is cooler outside that inside and open some windows.  The fan will pull cool air through your home, draw the cooled air into the attic (cooling the attic as well) and push it out your preexisting gable vents.  The fan is ultra quiet, since it is remotely located.
