Quiet Giant Whole House Fan

  • The Quiet Giant Whole House Fan Model# QC-4500 D is a powerful 4,712 CFM, 2 speed whole house fan. This revolutionary new product is the perfect addition to the current line of QC-2250 whole house fans. The Quiet Giant can be used to create a powerful, yet amazingly quiet flow of air in your home
  • Used alone or in combination with the other quiet cool fans, these amazing fans will give you unprecedented flexibility in designing the perfect whole house cooling solution to meet your specific needs. The Quiet Giant is mounted in the attic and connects to an attractive ceiling grill with 2 patented acoustical insulated ducts. This unique design helps to eliminates all vibration, rattle, and noise, common to all other whole house fans
  • The Quiet Giant consist of basically two of our QC-2250 units, but with larger, higher speed motors. The two fans each come with 6 foot long ducting that connected to one ceiling box and one ceiling grill for simple installation. The ceiling box is 14 1/4"x 36 1/4. Each motor has insulated, positive closing damper doors that prevent the intrusion of attic air back into the house when they are not in operation
  • The Quiet Giant is ideal for customers who want a single fan installed in a central hallway or it can be used in a multi-fan configuration, by installing the Quiet Giant in the central hallway and installing our smaller cfm QC fans in the bedrooms for maximum air flow and flexibility. When you purchase a fan from us, you get a complete system, which includes the fan, ducting, damper and grille. All that it needed for installation is your choice of controls
  • All of the "Classic Line" fans (except for the QC-1500) have the optional capability of having the motors being wired for two speeds. For two speed operation, your installer would need to simply remove the included 8ft. power cord and run a 3rd wire from the fan motor to the 3-wire wall switch and timer. If using a remote system or standard on/off wall switch, the fan will work perfectly as a single speed fan (as set in the factory)
  • The ideal setup for automatic operation, is to have your electrician hardwire the fan to a wall timer and standard off/on or 3 way switch (if wired for 2 speed operation) mounted next to each other on the wall at a central location such as a common hallway. This allows you to turn the fans off based on the time set on the timer or put the timer on hold and use the multiple wall switches to operate your fans individually
